Item Part Description

➊ Status Three LEDs that indicate the status of the Option Module and network
Indicators communications. Refer to Chapter 7, Troubleshooting.
➋ Data Rate Sets the DeviceNet data rate at which the Option Module
Switch communicates. Refer to Setting the Data Rate Switch on page 2-3.
➌ Node Address Sets the node address of the Option Module. Refer to Setting the Node
Switches Address Switches on page 2-2.
➍ DeviceNet A 5-pin connector to which a 5-pin linear plug (supplied with DeviceNet
Connector Option Module) can be connected to the DeviceNet cable.

1-2 Getting Started
Features The features of the Option Module include:
• Captive screws to secure and ground the module to the drive.

• Switches to set a node address and network data rate before applying
power to the drive. Alternately, you can disable the switches and use
Option Module parameters to configure these functions.
• Compatibility with various configuration tools to configure the
Option Module and host drive. The tools include the enhanced
PowerFlex 7-Class HIM (Human Interface Module) on the drive,
and drive-configuration software such as DriveExplorer (version
6.01 or higher) or DriveExecutive (version 5.01 or higher).
• Status indicators that report the status of the Option Module and
network communications. They are visible when the drive cover is
removed.
• Parameter-configurable 32-bit Datalinks in the I/O to meet

application requirements (16 for writing data from the network, and
16 for reading data to the network).
• Explicit Messaging and UCMM (Unconnected Message Manager)

support.
• Multiple data exchange methods, including Polled, Cyclic, and

Change of State (COS), to transmit data between the network and
Option Module.
• Master-Slave hierarchy that can be set up so that the Option Module
and PowerFlex 750-Series drive transmit data to and from a scanner
on the network.
• User-defined fault actions to determine how the Option Module and
connected drive respond to:
– I/O messaging communication disruptions (Comm Flt Action)

– Controllers in idle mode (Idle Flt Action)
– Explicit messaging disruptions for drive control via PCCC and
the CIP Register Object (Msg Flt Action)
• Faulted node recovery support. You can configure a device even

when it is faulted on the network if you have a configuration tool that
uses faulted node recovery and have set the Data Rate switch to
position “3.” With this configuration, the Option Module uses
parameter settings stored in EEPROM for the data rate and node
address instead of switch settings.
• Support for DPI routing, enabling access to any networked

PowerFlex 7-Class drive using DriveExplorer (version 6.01 or
higher) to monitor and configure that drive and its connected
peripherals.

Getting Started 1-3
Understanding Parameter The Option Module has two types of parameters:

Types • Device parameters are used to configure the Option Module to operate
on the network. Device parameters, when viewed using DriveExplorer
or DriveExecutive, appear below the 20-750-DNET listing in the
treeview in a separate Device Parameters folder . When viewed using
the HIM, these parameters appear in the DEV PARAM folder.
• Host parameters are used to configure the Option Module Datalink

transfer and various fault actions with the drive. Host parameters,
when viewed using DriveExplorer or DriveExecutive, appear below
the 20-750-DNET listing in the treeview in a separate Host
Parameters folder. When viewed using the HIM, these parameters
appear in the HOST PARAM folder.
Compatible Products At the time of publication, the Option Module is compatible with
Allen-Bradley PowerFlex 750-Series drives.

1-4 Getting Started
Safety Precautions Please read the following safety precautions carefully.
ATTENTION: Risk of injury or death exists. The

! PowerFlex drive may contain high voltages that can cause
injury or death. Remove all power from the PowerFlex drive,
and then verify power has been discharged before installing
or removing an Option Module.
ATTENTION: Risk of injury or equipment damage exists.
! Only personnel familiar with drive and power products and the
associated machinery should plan or implement the
installation, start up, configuration, and subsequent
maintenance of the drive using an Option Module. Failure to
comply may result in injury and/or equipment damage.
ATTENTION: Risk of equipment damage exists. The
! Option Module contains ESD (Electrostatic Discharge)
sensitive parts that can be damaged if you do not follow ESD
control procedures. Static control precautions are required
when handling the Option Module. If you are unfamiliar with
static control procedures, refer to Guarding Against
Electrostatic Damage (publication 8000-4.5.2).
! If the Option Module is transmitting control I/O to the drive,
the drive may fault when you reset the Option Module.
Determine how your drive will respond before resetting the
module.
! Host Parameters 33 - [Comm Flt Action], 34 - [Idle Flt
Action], and 36 - [Msg Flt Action] let you determine the
action of the Option Module and connected drive if I/O
communication is disrupted, the controller is idle, or explicit
messaging for drive control is disrupted. By default, these
parameters fault the drive. You can set these parameters so
that the drive continues to run. Precautions should be taken to
ensure that the settings of these parameters do not create a
risk of injury or equipment damage. When commissioning
the drive, verify that your system responds correctly to
various situations (for example, a disconnected cable or a
controller in idle state).
! When a system is configured for the first time, there may be
unintended or incorrect machine motion. Disconnect the
motor from the machine or process during initial system
testing.
! The examples in this publication are intended solely for
purposes of example. There are many variables and
requirements with any application. Rockwell Automation,
Inc. does not assume responsibility or liability (to include
intellectual property liability) for actual use of the examples
shown in this publication.

Preparing for an Installation Before installing the Option Module:

• Read the DeviceNet Product Overview Manual (publication
DNET-SO002), and the DeviceNet Cable System Planning and
Installation Manual (publication DN-6.7.2).
• Verify that you have all required equipment. Refer to Required

Equipment on page 1-3.
ATTENTION: Risk of equipment damage exists. The

! Option Module contains ESD (Electrostatic Discharge)
sensitive parts that can be damaged if you do not follow ESD
control procedures. Static control precautions are required
when handling the Option Module. If you are unfamiliar with
static control procedures, refer to Guarding Against
Electrostatic Damage (publication 8000-4.5.2).

2-2 Installing the Option Module
Setting the Node Address Set the Option Module Node Address switches (bottom two switches –
Switches see Figure 2.1) by rotating the switches to the desired value for each
digit.
Important: Each node on the DeviceNet network must have a unique

address. Set the node address before power is applied
because the Option Module uses the node address it detects
when it first receives power. To change a node address, you
must set the new value and then remove and reapply power
to (or reset) the Option Module, or disconnect and
reconnect the DeviceNet network cable.

4-9 Sets the Option Module to the Auto data rate — a data rate used by other network
devices. Another device on the network must be set to a data rate. The default switch
setting is 9.
The switch settings can be verified by viewing Diagnostic Device Item

number 53 (page 7-6) using an enhanced PowerFlex 7-Class HIM,
DriveExplorer software, or DriveExecutive software.
Connecting the Option The Option Module can be installed in the PowerFlex 750-Series Drive
Module to the Drive control pod in Port 4, 5 or 6. For details, see the Network
Communication Option Module Installation Instructions (publication
750COM-IN002), provided with the Option Module. Note that the
Option Module is shown already installed in the drive in Figure 2.1 and
Figure 2.2.
Important: Remove power from the drive before installing the Option
Module in the drive control pod.
Important: After inserting the Option Module into Port 4, 5 or 6, make

sure to tighten the Option Module screws within the
specified torque range to the drive control pod to properly
ground the Option Module to the drive.

Connecting the Option

ATTENTION: Risk of injury or death exists. The
Module to the Network
! PowerFlex drive may contain high voltages that can cause
injury or death. Remove power from the drive, and then
verify power has been discharged before connecting the
Option Module to the network.
1. Remove power from the drive.
2. Remove the drive cover and lift up the drive HIM bezel to its open
position to access the drive control pod.
3. Use static control precautions.
4. Connect a DeviceNet cable to the network, and route it through the

bottom of the drive. DeviceNet Thin cable with an outside diameter
of 6.9 mm (0.27 in.) is recommended.
Important: Maximum cable length depends on data rate. For

details, refer to Data Rate in the Glossary.
5. Connect the 5-pin linear plug (provided with the Option Module) to
the DeviceNet cable (Figure 2.3). If a replacement plug is needed,
the replacement plug part number is 1799-DNETSCON.

the wires on the plug match the color codes on the socket.

Applying Power
ATTENTION: Risk of equipment damage, injury, or death
! exists. Unpredictable operation may occur if you fail to verify
that parameter settings are compatible with your application.
Verify that settings are compatible with your application
before applying power to the drive.
Apply power to the drive. The Option Module receives its power from
the drive. When you apply power to the Option Module for the first
time, its topmost “PORT” status indicator should be solid green or
flashing green after an initialization. If it is red, there is a problem.
Refer to Chapter 7, Troubleshooting.
Start-Up Status Indications

After power has been applied, the drive STS (status) indicator can be
viewed on the front of the drive and the Option Module status indicators
can be viewed (Figure 2.4) with the drive cover open or removed.

Configuring/Verifying Key Drive Parameters

The PowerFlex 750-Series drive can be separately configured for the
control and Reference functions in various combinations. For example,
you could set the drive to have its control come from a peripheral or
terminal block with the Reference coming from the network. Or you
could set the drive to have its control come from the network with the
Reference coming from another peripheral or terminal block. Or you
could set the drive to have both its control and Reference come from the
network.

The following steps in this section assume that the drive will receive the
Logic Command and Reference from the network.
1. Use drive Parameter 545 - [Speed Ref A Sel] to set the drive speed
Reference to the port (slot) in which the Option Module is installed
(for example, Port 4 Reference).
2. Verify that drive Parameter 930 - [Speed Ref Source] is reporting
that the source of the Reference to the drive is the port in which the
Option Module is installed (for example, Port 4 Reference). This
ensures that any Reference commanded from the network can be
monitored by using drive Parameter 002 - [Commanded SpdRef]. If
a problem occurs, this verification step provides the diagnostic
capability to determine whether the drive/Option Module or the
network is the cause.
3. If hard-wired discrete digital inputs are not used to control the

drive, verify that all unused digital input parameters are set to “Not
Used.”
Commissioning the Option To commission the Option Module, you must set a unique node address
Module on the network. (Refer to Setting the Node Address Switches on
page 2-2, and the Glossary for details about node addresses.)
Important: New settings are recognized only when power is applied to

the Option Module or it is reset. After you change
parameter settings, cycle power or reset the Option Module.

Configuration Tools The Option Module stores parameters and other information in its own
non-volatile memory. You must, therefore, access the Option Module to
view and edit its parameters. The following tools can be used to access
the Option Module parameters:
Tool Refer to…

Important: For the HIM screens shown throughout this chapter, the
Option Module is assumed to be installed in drive Port 04.
If your Option Module is installed in a different drive port,
that port would appear instead of Port 04.
Using the Enhanced If your drive has an enhanced PowerFlex 7-Class HIM, it can be used to
PowerFlex 7-Class HIM access parameters in the Option Module. For details on viewing and
editing parameters, refer to the Enhanced PowerFlex 7-Class HIM User
Manual (publication 20HIM-UM001).

3-2 Configuring the Option Module
Using the HIM to Access 1. Display the Status screen, which is shown on HIM power up.
Parameters in the Option 2. Use the or key to scroll to the Port in which the
Module DeviceNet Option Module is installed.
3. Press the PAR# soft key to display the Jump to Param # entry
pop-up box.
4. Use the numeric keys to enter the desired parameter number, or use
the S or T soft key to scroll to the desired parameter number.
Setting the Node Address If the Data Rate switch (Figure 2.2) is set to position “3,” the value of
Device Parameter 07 - [Net Addr Cfg] determines the node address.
When the Data Rate switch is set to any other position, the Node
Address switches determine the node address. We recommend that you
do not use node address 63 because all new devices on the network use
this address as the default address. Also, node address 63 is used for
Automatic Device Recovery (ADR).
1. Set the value of Device Parameter 07 - [Net Addr Cfg] to a unique

node address.

2. Reset the Option Module; see Resetting the Option Module on

page 3-8.
The NET A status indicator will be solid green or flashing green if

the node address is correctly configured, and the Option Module is
connected to an operational network.
Setting the Data Rate If the Option Module Data Rate switch (Figure 2.2) is set to position
“3” (Program), the value of Device Parameter 09 - [Net Rate Cfg]
determines the data rate. The Autobaud setting will detect the data rate
used on the network if another device is setting the data rate. Your
application may require a different setting.
1. Set the value of Device Parameter 09 - [Net Rate Cfg] to the data
rate at which your network is operating.

page 3-8.
Setting a Master-Slave This procedure is only required if Datalinks are used to write or read
Hierarchy (Optional) data of the drive or its connected peripherals. A hierarchy determines
the type of device with which the Option Module exchanges data. In a
Master-Slave hierarchy, the Option Module exchanges data with a
master, such as a scanner (1756-DNB, 1771-SDN, 1747-SDN, etc.).
Enabling Datalinks To Write Data

The controller output image (controller outputs-to-drive) can have
anywhere from 0 to 16 additional 32-bit parameters (Datalinks). The
number of additional parameters is configured using Device Parameter
02 - [DLs From Net Cfg].
Important: Always use the Datalink parameters in consecutive

numerical order, starting with the first parameter. For
example, use Host Parameters 01, 02, and 03 to configure 3
Datalinks to write data. Otherwise, the network I/O
connection will be larger than necessary, which needlessly
increases controller response time and memory usage.
Host Parameters 01 - [DL From Net 01] through 16 - [DL From Net
16] control which parameters in the drive, Option Module, or any other
connected peripheral receive the values from the network. The
enhanced PowerFlex 7-Class HIM, DriveExplorer, and DriveExecutive
provide user-friendly screens to help select the drive or peripheral by
port number and the parameter by name. As an alternate method, the
parameter value can be set manually by number using this formula:
From Net Parameter Value = (10000 * port number) + (Destination Parameter Number).
For example, suppose you want to use Host Parameter 01 - [DL From
Net 01] to write to Parameter 03 of an optional encoder module plugged
into drive Port 5. Using the formula, the value for Host Parameter 01 -
[DL From Net 01] would be (10000 * 5) + (3) = 50003.
1. Set the value of Device Parameter 02 - [DLs From Net Cfg] to the
number of contiguous controller-to-drive Datalinks that are to be
included in the network I/O connection.

page 3-8.
3. Since the Logic Command and Reference is always used in the

Option Module, configure the parameters in the drive to accept the
Logic Command and Reference from the Option Module. If the
controller is going to be used for speed reference via the Option
Module, set Parameter 545 - [Speed Ref A Sel] in a PowerFlex 755
drive to the port in which the Option Module is installed (for
example, Port 4 Reference). Also, verify that the mask parameters
in the drive (for example, Parameter 324 - [Logic Mask]) are
configured to receive the desired logic from the Option Module.
Refer to the documentation for your drive for details.
The Option Module is ready to receive input data from the master
(controller). You must now configure the controller to recognize and
transmit I/O to the Option Module. Refer to Chapter 4,
Configuring the I/O.
Enabling Datalinks To Read Data

The controller input image (drive-to-controller inputs) can have
anywhere from 0 to 16 additional 32-bit parameters (Datalinks). The
number of additional parameters is configured using Device Parameter
04 - [DLs To Net Cfg].
Important: Always use the Datalink parameters in consecutive

numerical order, starting with the first parameter. For
example, use Host Parameters 17, 18, 19, 20, and 21 to
configure 5 Datalinks to read data. Otherwise, the network
I/O connection will be larger than necessary, which
needlessly increases controller response time and memory
usage.
Host Parameters 17 - [DL To Net 01] through 32 - [DL To Net 16]

control which parameters in the drive, Option Module, or any other
connected peripheral send the values to the network. The enhanced
PowerFlex 7-Class HIM, DriveExplorer, and DriveExecutive provide
user-friendly screens to help select the drive or peripheral by port
number and the parameter by name. As an alternate method, the
parameter value can be set manually by number using this formula:

To Net Parameter Value = (10000 * Port Number) + (Origination Parameter Number)
For example, suppose you want to use Host Parameter 17 - [DL To

Net 01] to read Parameter 2 of an optional I/O module plugged into
drive Port 4. Using the formula, the value for Host Parameter 17 - [DL
To Net 01] would be (10000 * 4) + (2) = 40002.
1. Set the value of Device Parameter 04 - [DLs To Net Cfg] to the

number of contiguous drive-to-controller Datalinks that are to be
included in the network I/O connection.

The Option Module is ready to send output data to the master

(controller). You must now configure the controller to recognize and
transmit I/O to the Option Module. Refer to Chapter 4,
Configuring the I/O.
Selecting COS, Cyclic or The data exchange is the method that the Option Module uses to
Polled (Optional) exchange data on the DeviceNet network. Polled is the default and is
recommended — unless one of the other following data exchanges,
which the adapter supports, is more appropriate for your application:
• COS (Change of State) • Polled and COS

• Cyclic • Polled and Cyclic
• Polled
If “Polled and COS” or “Polled and Cyclic” is used, the Option Module
transmits and receives the I/O from the polled messages. It transmits
only a Logic Status and Feedback in COS or Cyclic messages. Other
data is transmitted in Polled messages.
Cyclic and Polled data exchanges are configured in the scanner, so you
only need to set the I/O configuration in the Option Module. COS data
exchange must be configured in both the Option Module and the
scanner. You need to set the I/O configuration and COS parameters in
the Option Module.

Using COS (Change of State) Data Exchange

1. Set Device Parameter 11 - [COS Status Mask] for the bits in the
Logic Status word that should be checked for changes. For the
Logic Status bit definitions, refer to Appendix D or the drive
documentation.
TIP: The HIM shows 32-bit Bit-type parameters in two 16-bit sets.
By default, the lower 16-bit set (bits 00-15) is shown. To view the
upper 16-bit set (bits 16-31), press the UPPER soft key. To view the
lower 16-bit set again, press the LOWER soft key. To select each bit
position, use the W or X soft key or the or numeric key.
2. To edit any of the bits, press the EDIT soft key to display the Edit

The Option Module is now configured for COS data exchange. You
must configure the scanner to allocate it using COS (Chapter 4,
Configuring the I/O).

Setting a Fault Action By default, when I/O communications are disrupted (for example, the
network cable is disconnected), the controller is idle (in program mode
or faulted) or explicit messaging for drive control is disrupted, the drive
responds by faulting. You can configure a different response to:
• Disrupted I/O communication by using Host Parameter 33 -

[Comm Flt Action].
• An idle controller by using Host Parameter 34 - [Idle Flt Action].
• Disrupted explicit messaging for drive control via PCCC and the CIP
Register Object by using Host Parameter 35 - [Msg Flt Action].

! Host Parameters 33 - [Comm Flt Action], 34 - [Idle Flt
Action], and 35 - [Msg Flt Action] let you determine the
action of the Option Module and connected drive if I/O
communication is disrupted, the controller is idle, or explicit
messaging for drive control is disrupted. By default, these
parameters fault the drive. You can set these parameters so
that the drive continues to run. Precautions should be taken to
ensure that the settings of these parameters do not create a
risk of injury or equipment damage. When commissioning the
drive, verify that your system responds correctly to various
situations (for example, a disconnected network cable,
controller in idle state or explicit message control disruption).
Changing the Fault Action

Set the values of Host Parameters 33 - [Comm Flt Action], 34 - [Idle
Flt Action], and 35 - [Msg Flt Action] to the desired responses:
Value Action Description
0 Fault The drive is faulted and stopped. (Default)
1 Stop The drive is stopped, but not faulted.
2 Zero Data The drive is sent 0 for output data. This does not command a stop.
3 Hold Last The drive continues in its present state.
4 Send Flt Cfg The drive is sent the data that you set in the fault configuration
parameters (Host Parameters 37 - [Flt Cfg Logic], 38 - [Flt Cfg Ref],
and 39 - [Flt Cfg DL 01] through 54 - [Flt Cfg DL 16]).

Setting the Fault Configuration Parameters

If you set Host Parameter 33 - [Comm Flt Action], 34 - [Idle Flt
Action] or 35 - [Msg Flt Action] to “Send Flt Cfg,” the values in the
following parameters are sent to the drive after an I/O communications
fault, idle fault, and/or explicit messaging for drive control fault occurs.
You must set these parameters to values required by your application.
Parameter Description
Host Parameter 37 - [Flt Cfg Logic] A 32-bit value sent to the drive for Logic Command.
Host Parameter 38 - [Flt Cfg Ref] A 32-bit REAL (floating point) value sent to the drive for
Reference.
Host Parameter 39 - [Flt Cfg DL 01] A 32-bit REAL (floating point) or 32-bit integer value
through sent to the drive for a Datalink.
Host Parameter 54 - [Flt Cfg DL 16]
Changes to these parameters take effect immediately. A reset is not required.
Resetting the Option Changes to switch settings and some Option Module parameters require
Module you to reset the Option Module before the new settings take effect. You
can reset the Option Module by power cycling the drive or by using
Device Parameter 14 - [Reset Module].
ATTENTION: Risk of injury or equipment damage exists. If

! the Option Module is transmitting control I/O to the drive, the
drive may fault when you reset the Option Module.
Determine how your drive will respond before resetting the
Option Module.
Set Device Parameter 14 - [Reset Module] to “1” (Reset Module).

cycling the drive. When you enter “2” (Set Defaults), the Option
Module will set ALL of its Device and Host parameters to their factory
default values. (This is the same as pressing the ALL soft key when
using the MEMORY folder method described in Restoring Option
Module Parameters to Factory Defaults on page 3-9.) After performing
a Set Defaults, you must enter “1” (Reset Module) or power cycle the

drive so that the new values take effect. Thereafter, the value of this
parameter will be restored to “0” (Ready).
Important: When performing a Set Defaults, the drive may detect a

conflict and then not allow this function to occur. If this
happens, first resolve the conflict and then repeat a Set
Defaults action.
TIP: If your application allows, you can also reset the Option Module
by cycling power to the drive (resetting the drive) or by using the HIM’s
Reset Device function located in the drive’s DIAGNOSTIC folder.
Restoring Option Module As an alternate method, you can restore the Option Module parameters
Parameters to Factory using a MEMORY folder menu item instead of using Device
Defaults Parameter 14 - [Reset Module] described in Resetting the Option
Module on page 3-8. The MEMORY folder method provides two ways
to restore the Option Module Device and Host parameters:
• ALL—restores ALL Option Module Device and Host parameters to
their factory default values.
• MOST—restores MOST Option Module Device and Host
parameters—except the following which are used for network setup:
– Device Parameter 07 - [Net Addr Cfg]
– Device Parameter 09 - [Net Rate Cfg]
To restore Option Module Device and Host parameters to their factory
default values:

Chapter 4
Configuring the I/O
This chapter provides instructions on how to configure a Rockwell

Automation ControlLogix controller to communicate with the Option
Module and connected PowerFlex drive.
Topic Page
Using RSLinx Classic 4-1
ControlLogix Example 4-2
Important: Since the Option Module and PowerFlex 750-Series drive

are 32-bit devices, the ControlLogix controller (also a
32-bit platform) is used for example purposes in this
chapter and throughout this manual. We recommend using
only a 32-bit platform Logix controller with this Option
Module and PowerFlex 750-Series drive to simplify
configuration and ladder logic programs, and maximize
drive performance. If you must use a 16-bit controller
(PLC-5, SLC 500, etc.), we recommend using a
20-COMM-D adapter that is mounted onto a
20-750-20COMM Option Card installed in drive Port 6. In
this case, refer to the Rockwell Automation Technical
Support Knowledgebase web site at
www.rockwellautomation.com/knowledgebase for details
on configuring and using the I/O, and explicit messaging.
Using RSLinx Classic RSLinx Classic, in all its variations (Lite, Gateway, OEM, etc.), is used
to provide a communication link between the computer, network, and
controller. RSLinx Classic requires its network-specific driver to be
configured before communications are established with network
devices. To configure the RSLinx driver:
1. Start RSLinx and select Communications > Configure Drivers to

display the Configure Drivers screen.
2. In the Available Driver Types box, select “DeviceNet Drivers” and

then click Add New to display the DeviceNet Driver Selection
screen.
3. In the Available DeviceNet Drivers list, select the PC connection

adapter (1784-PCD, 1784-PCID, 1784-PCIDS or 1770-KFD)
connected to your computer and then click Select to display the
Driver Configuration screen.
4. Configure the driver for your computer and network settings and
click OK. The Configure Drivers screen reports the progress of the
configuration.

ControlLogix Example Example Network

After the Option Module is configured, the connected drive and Option
Module will be a single node on the network. This section provides the
steps needed to configure a simple DeviceNet network (see Figure 4.2).
In our example, we will configure a ControlLogix controller with
1756-DNB scanner to communicate with a drive using Logic
Command/Status, Reference/Feedback, and 32 Datalinks (16 to read/16
to write) over the network.

1756-DNB scanner appears under the I/O Configuration folder
(Figure 4.6) with its assigned name. For convenience, keep the
project open. Later in this chapter the project will need to be
downloaded to the controller.
Figure 4.6 RSLogix 5000: I/O Configuration Folder

Using RSNetWorx for DeviceNet to Configure/Save the I/O to the

Scanner
After adding the scanner to the I/O configuration, you now must
configure and save the I/O to the scanner.
1. Start RSNetWorx for DeviceNet. In the RSNetWorx for DeviceNet

window, select File > New to display the New File screen. Then
select “DeviceNet Configuration” as the network configuration
type, and click OK.
2. Select Network > Online to display the Browse for Network screen
(Figure 4.7).

3. Expand the communications path from your computer to the

DeviceNet scanner. Figure 4.8 shows our example navigating to
devices that are on a DeviceNet network. Depending on the
communication link you are using, the navigation path may be
different. After selecting a valid path to the DeviceNet network (for
this example, A, DeviceNet), click OK.

Figure 4.8 Expanded Browse for Network Screen
If a message box appears about uploading or downloading

information, click OK.
4. As the selected DeviceNet path is browsed, RSNetWorx for

DeviceNet creates a graphical representation of the devices on the
network (Figure 4.9).
Figure 4.9 RSNetWorx for DeviceNet Graph View Screen
If the icon for the drive (for this example, PowerFlex 755) on the
network appears as Unrecognized Device, use RSNetWorx for
DeviceNet to create the PowerFlex 750-Series drive EDS file.
The EDS file for a PowerFlex 750-Series drive differs from EDS
files for all other PowerFlex 7-Class drives in that the file does not
contain any drive or peripheral parameters. Therefore, when the
EDS file is being created for a PowerFlex 750-Series drive, no
parameters will be uploaded and the “Parameters” tab that normally
appears on the Drive Properties screen will not appear.

5. Either create the EDS file by uploading it from the device on the
network, or download the EDS file from the Rockwell Automation
web site:
Creating the EDS File from Online DeviceNet Network
A. Right-click the Unrecognized Device icon and select Register

Device in the menu. The EDS Wizard appears (Figure 4.10).
Figure 4.10 EDS Wizard Screen
B. Click Next to start creating the EDS file.
C. Select Create an EDS file and click Next. (If the EDS file is
already downloaded and resides on your computer, select the
Register an EDS file option and click Next. Then follow the
screen prompts and disregard the remaining steps D through H
in this procedure.)
D. Enter a description (if desired) and click Next.
E. Check the Polled box, enter 8 into the Input Size and Output
Size boxes (which accounts for just the basic I/O), and click
Next. RSNetWorx for DeviceNet will upload the EDS file from
the drive.
F. Click Next to display the icon options for the node. We
recommend using the icon for your PowerFlex 750-Series
drive. You can change icons by clicking Change icon.
G. Click Next to view a summary, and then click Next again to
accept it.
H. Click Finish to finish creating the EDS file. A new icon

represents your PowerFlex 750-Series drive and
communications Option Module in the RSNetWorx for
DeviceNet Graph View screen.

Downloading the EDS File from the Network
A. Go to this Rockwell Automation web site:

www.rockwellautomation.com/resources/eds
B. On the web site, enter the Network and Device Type search
criteria as shown in Figure 4.11. In the Keyword entry field,
enter the type of PowerFlex 750-Series drive (for this example,
PowerFlex 755), noting that this field is case sensitive and
space sensitive:
Figure 4.11 Example Web Site Search Criteria for EDS File
Then click Search. Due to the large number of EDS files, this
may take several minutes.
C. On the search results screen, click the hyperlink for the EDS
file in the Brand Column.
D. Click Download File. Then click Save to save the EDS file to
an appropriate location on your computer.
E. Launch the EDS Hardware Installation Tool in the Rockwell

Software folder and follow the screen prompts to add the EDS

Figure 4.13 1756-DNB Module Tab Screen
8. Edit the following:

Box Setting
Interscan Delay Sets the scanner time delay between consecutive I/O scans on the
network. For this example, it is recommended to leave the default setting
of 10 milliseconds. Note: When numerous drives are on the network and
the drives are faulting on a Comm Loss, increasing this value may help.
Foreground… Sets the ratio of foreground to background polls. For this example, it is
recommended to leave the default setting of 2.
Slot Sets the slot location in which the scanner is installed. For this example,
Slot 3 is selected.
Then click Apply.

9. Click the Scanlist tab to begin the drive I/O configuration. The
Available Devices window (left) shows devices that are presently
on the DeviceNet network but are not yet configured. The Scanlist
window (right) shows devices that are presently on the DeviceNet
network and are configured.
TIP: The Automap on Add box is checked by default and allows

RSNetWorx for DeviceNet to automatically map the drive I/O into
the scanner in the next available registers. The mapping is based on
the minimum I/O requirements (8 bytes for input and 8 bytes for
output) that the scanner obtains from the drive EDS file.
For this example, uncheck the Automap on Add box. Then select
the PowerFlex 755 drive in the Available Devices window and click
the > button to move it to the Scanlist window (Figure 4.14).
Figure 4.14 1756-DNB Scanlist Tab Screen
Box Setting
Node Active Activates/deactivates the scanlist in the 1756-DNB for the selected
device. For this example, keep the box checked.
Device Type These Electronic Key category check boxes select how specific the
Vendor device in the scanlist must be for the 1756-DNB to match its
Product Code compatibility for I/O operation. The more boxes that are checked, the
more specific the device must be to operate. For this example, leave the
Major Revision default boxes (Device Type, Vendor, and Product Code) checked.
10. Click Edit I/O Parameters… to display the Edit I/O Parameters
screen (Figure 4.15) for the PowerFlex 755 drive used in this
example.

Figure 4.15 Edit I/O Parameters Screen
A. Select the type(s) of data exchange (Polled, Change of State,

and/or Cyclic). For this example, we selected Polled, which is
highly recommended.
B. Enter the number of bytes that are required for your I/O in the
Input Size and Output Size boxes. For the example in this
manual, all 16 [DL From Net xx] and all 16 [DL To Net xx]
are used, resulting in an Input Size of “72” and an Output Size
of “72.” To determine the byte sizes for your application, either
access Option Module Diagnostic Items 7 and 8 respectively or
calculate them:
Determining Byte Sizes By Accessing Diagnostic Items 7 and 8
Use the HIM, DriveExplorer or DriveExecutive to access

Diagnostic Items 7 and 8. The Option Module automatically
calculates the number of bytes for the Input Size and Output
Size based on the values of Device Parameters 2 - [DLs From
Net Cfg] and 4 - [DLs To Net Cfg] configured in Setting a
Master-Slave Hierarchy (Optional) on page 3-3.
Determining Byte Sizes By Calculation
You can easily calculate the number of bytes for the Input Size
and Output Size. Since the Option Module always uses the
32-bit Logic Command, 32-bit Feedback, 32-bit Logic Status,
and 32-bit Reference, at least 8 bytes must be set for both the
Input Size and Output Size. (A 32-bit word is four bytes.) If any
or all of the drive’s sixteen 32-bit Datalinks are used (see
Setting a Master-Slave Hierarchy (Optional) on page 3-3),
increase the Input and Output Size settings accordingly. To do
this:
– Input Size: Multiply the number of Datalinks used to write data

(value of Device Parameter 02 - [DLs From Net Cfg]) by 4
bytes, and add this result to the minimum 8 bytes. For example,
if Parameter 02 has a value of “3,” add 12 bytes (3 x 4 bytes)
to the required minimum 8 bytes for a total of 20 bytes.

– Output Size: Multiply the number of Datalinks used to read data

(value of Device Parameter 04 - [DLs To Net Cfg]) by 4 bytes,
and add this result to the minimum 8 bytes. For example, if
Parameter 04 has a value of “7,” add 28 bytes (7 x 4 bytes) to
the required minimum 8 bytes for a total of 36 bytes.
11. Set the scan rate for the selected data exchange method. (For more
information about scan rates, refer to RSNetWorx for DeviceNet
online help.)
Data Exchange Method Rate Field to Set
Polled Poll Rate
Change of State Heartbeat Rate
Cyclic Send Rate
12. Click OK. If a Scanner Configuration Applet appears, click Yes to

continue. The Edit I/O Parameters screen closes and then the
1756-DNB Scanlist tab screen (Figure 4.14) reappears.
13. Click the Input tab to display the input registers for the 1756-DNB.
Click AutoMap to map the drive input image to the 1756-DNB as
shown in Figure 4.16.
TIP: If your RSLogix 5000 project requires a different starting

DWord (double word, 32-bit) than the default value of 0 for the
drive input image, set the Start DWord field to the appropriate value.
Figure 4.16 1756-DNB Input Tab Screen
14. Click the Output tab to display the output registers for the
1756-DNB. Click AutoMap to map the drive output image to the
1756-DNB as shown in Figure 4.17.
TIP: If your RSLogix 5000 project requires a different starting

DWord (double word, 32-bit) than the default value of 0 for the drive
output image, set the Start DWord field to the appropriate value.

Figure 4.17 1756-DNB Output Tab Screen
15. Click OK. If the Scanner Configuration Applet appears asking to

download these settings to the 1756-DNB, click Yes.
16. Click File > Save. If this is the first time you saved the project, the
Save As dialog box appears. Navigate to a folder, type a file name,
and click Save to save the configuration to a file on your computer.
17. When configuring the I/O for additional PowerFlex 750-Series
drives on the network, repeat Steps 9 through 16.
Important: When all Datalinks in each drive are used (18 DINTs of
I/O per drive), a maximum of 6 PowerFlex 750-Series
drives can be mapped. This is due to the amount of I/O
available in the 1756-DNB scanner, which is 124
DINTs maximum.

Setting Datalinks in the Drive (Optional)

After configuring the 1756-DNB, Datalinks (if used) must be set to
parameters that are appropriate for your application.
Using the drive HIM, DriveExecutive or DriveExplorer, set the

Datalinks in the drive. For this example, the following Datalink values
are used.

TIP: The Host [DLs From Net xx] parameters are inputs into the drive
that come from controller outputs (for example, data to write to a drive
parameter). The Host [DLs To Net xx] parameters are outputs from the
drive that go to controller inputs (for example, data to read a drive
parameter).

Chapter 5
Using the I/O
This chapter provides information and examples that explain how to

control, configure, and monitor a PowerFlex 750-Series drive using the
configured I/O.

Using Datalinks 5-4
Example Ladder Logic Program Information 5-5

About I/O Messaging On CIP-based networks, including DeviceNet, I/O connections are used
to transfer the data which controls the PowerFlex drive and sets its
Reference. I/O can also be used to transfer data to and from Datalinks in
PowerFlex 750-Series drives.
The Option Module includes the Logic Command, Logic Status,

Reference, and Feedback (all as 32-bit words). This requires 8 bytes for
the Input Size and 8 bytes for the Output Size in the controller’s I/O
image. This basic I/O must always be configured in the DeviceNet
scanner using RSNetWorx for DeviceNet. Additional I/O, if needed,
can be set using up to 16 Datalinks to write data and/or up to 16
Datalinks to read data. When using any combination of these Datalinks,
add 4 bytes for each Datalink to the basic I/O Input Size and/or Output
Size.
Chapter 3, Configuring the Option Module, and Chapter 4, Configuring

the I/O, discuss how to configure the Option Module and controller on
the network for the required I/O. The Glossary defines the different
options. This chapter discusses how to use I/O after you have
configured the Option Module and controller.

5-2 Using the I/O
Understanding the The terms input and output are defined from the controller’s point of
ControlLogix Controller I/O view. Therefore, output I/O is data that is produced by the controller and
Image consumed by the Option Module. Input I/O is status data that is
produced by the Option Module and consumed as input by the
controller. The I/O image will vary based on how many of the drive’s
32-bit Datalinks (Host DL From Net 01-16 and Host DL To Net
01-16) are used.
If all available I/O is not used, the image is truncated. The image always
uses consecutive words starting at word 0.
Table 5.A shows the I/O image when using all of the 32-bit Datalinks.
Table 5.A ControlLogix I/O Image for PowerFlex 750-Series Drives (32-bit Logic
Command/Status, Reference/Feedback, and Datalinks)
DINT Output I/O DINT Input I/O
0 Logic Command 0 Logic Status
1 Reference 1 Feedback
2 DL From Net 01 2 DL To Net 01
Using Logic Command/ The Logic Command is a 32-bit word of control data produced by the
Status controller and consumed by the Option Module. The Logic Status is a
32-bit word of status data produced by the Option Module and
consumed by the controller.
When using a ControlLogix controller, the Logic Command word is

always DINT 0 in the output image and the Logic Status word is always
DINT 0 in the input image.
This manual contains the bit definitions for compatible products

available at the time of publication in Appendix D, Logic Command/
Status Words for PowerFlex 750-Series Drives.

Using the I/O 5-3
Using Reference/Feedback The Reference is a 32-bit REAL (floating point) piece of control data
produced by the controller and consumed by the Option Module. The
Feedback is a 32-bit REAL (floating point) piece of status data
produced by the Option Module and consumed by the controller.
The Reference and Feedback values represent engineering units. For

example, a 32-bit REAL Reference value of “30.0” equals a Reference
of 30.0 Hz. Note that the commanded maximum speed can never
exceed the value of drive Parameter 520 - [Max Fwd Speed]. Table 5.B
shows example References and their results for a PowerFlex 750-Series
drive that has its Parameter 37 - [Maximum Freq] set to 130 Hz and
Parameter 520 - [Max Fwd Speed] set to 60 Hz.
When using a ControlLogix controller, the 32-bit REAL Reference

word is always DINT 1 in the output image and the 32-bit REAL
Feedback word is always DINT 1 in the input image. Because the I/O
image is integer-based and the Reference and Feedback are floating
point, a COP (Copy) instruction or UDDT is required to correctly write
values to the Reference and read values from the Feedback. See the
ladder logic program examples in Figure 5.5 and Figure 5.6.

The effects of values less than 0.0 depend on whether the PowerFlex 750-Series drive
uses a bipolar or unipolar direction mode. Refer to the drive User Manual for details.
(2)
The drive runs at 60 Hz instead of 130 Hz or 65 Hz because drive Parameter 520 - [Max
Fwd Speed] sets 60 Hz as the maximum speed.

5-4 Using the I/O
Using Datalinks A Datalink is a mechanism used by PowerFlex drives to transfer data to

and from the controller. Datalinks allow a drive parameter value to be
changed without using an Explicit Message. When enabled, each
Datalink occupies one 32-bit word in a ControlLogix controller.
The following rules apply when using PowerFlex 750-Series drive

Datalinks:
• The target of a Datalink can be any Host parameter, including those

of a peripheral. For example, drive parameter 535 - [Accel Time 1]
can be assigned to any or all Option Modules installed in the drive.
• The data passed through the Datalink mechanism is determined by

the settings of:
Device Parameter 02 - [DLs From Net Cfg] Host Parameters 01-16 - [DL From Net 01-16]
Device Parameter 04 - [DLs To Net Cfg] Host Parameters 17-32 - [DL To Net 01-16]
Important: A reset is always required after configuring Datalinks so

that the changes take effect.
• When a Datalink I/O connection is active, that Datalink is locked

and cannot be changed until that I/O connection becomes idle or
inactive.
• When you use a Datalink to change a value, the value is NOT written
to the Non-Volatile Storage (NVS). The value is stored in volatile
memory and lost when the drive loses power. Thus, use Datalinks
when you need to change a value of a parameter frequently.
Datalinks for PowerFlex 750-Series peripherals (embedded EtherNet/IP

adapter and option modules such as an encoder or a communication
module) are locked when the peripheral has an I/O connection with a
controller. When a controller has an I/O connection to the drive, the
drive does not allow a reset to defaults, configuration download or
anything else that could change the makeup of the I/O connection in a
running system. The I/O connection with the controller must first be
disabled to allow changes to the respective Datalinks.
Depending on the controller being used, the I/O connection can be

disabled by:
• Inhibiting the module in RSLogix 5000

• Putting the controller in Program mode
• Placing the scanner in idle mode
• Disconnecting the drive from the network
DeviceLogix Datalinks are also locked while the DeviceLogix program

is running. The DeviceLogix program must first be disabled to allow
changes to the Datalinks. Set DeviceLogix parameter 53 - [DLX
Operation] to “DisableLogic” to disable the logic (the parameter value
will then change to “LogicDisabld.”

Using the I/O 5-5
Example Ladder Logic The example ladder logic programs in the sections of this chapter are
Program Information intended for and operate PowerFlex 750-Series drives.
Functions of the Example Programs

The example programs enable you to:
• Receive Logic Status information from the drive.

• Send a Logic Command to control the drive (for example, start, stop).
• Send a Reference to the drive and receive Feedback from the drive.
• Send/receive Datalink data to/from the drive.
Logic Command/Status Words

These examples use the Logic Command DINT and Logic Status DINT
for PowerFlex 750-Series drives. Refer to Appendix D, Logic
Command/Status Words for PowerFlex 750-Series Drives to view
details.

TIP: The Host [DL From Net xx] parameters are inputs into the drive
that come from controller outputs (for example, data to write to a drive
parameter). The Host [DL To Net xx] parameters are outputs from the
drive that go to controller inputs (for example, data to read a drive

Using the I/O 5-7
Controller Tags
When you add the Option Module and drive to the I/O configuration
(Chapter 4), RSLogix 5000 automatically creates generic
(non-descriptive) controller tags. In this example program, the
following controller tags are used.
Figure 5.1 ControlLogix Controller Tags for Example Ladder Logic Program
You can expand the Output and Input tags to reveal the output and input
configuration. The Output tag for this example program requires
eighteen 32-bit words of data (see Figure 5.2). The Input tag for this
example requires eighteen 32-bit words of data (see Figure 5.3).

Enabling the DeviceNet Scanner
A rung in the ladder logic must be created and assigned to the

1756-DNB scanner Command Register Run bit. This rung (Figure 5.7)
enables the scanner to transfer I/O on the network.
Figure 5.7 Rung for Command Register Run Bit
Important: This rung must always be included in the ladder logic

program.
Example Datalink Data
The Datalink data used in the example program is shown in Figure 5.8.
Note that to describe the parameters to which the Datalinks are
assigned, you may want to add descriptions to the automatically-created
generic controller tags or create User Defined Data Types (UDDT),
which were used in the example screen below.

Notes:

Chapter 6
Using Explicit Messaging
This chapter provides information and examples that explain how to use
Explicit Messaging to configure and monitor the Option Module and
connected PowerFlex 750-Series drive.
Topic Page
About Explicit Messaging 6-1
Performing Explicit Messages 6-2

ATTENTION: Risk of equipment damage exists. If Explicit
! Messages are programmed to write parameter data to
Non-Volatile Storage (NVS) frequently, the NVS will quickly
exceed its life cycle and cause the drive to malfunction. Do
not create a program that frequently uses Explicit Messages
to write parameter data to NVS. Datalinks do not write to
NVS and should be used for frequently changed parameters.
Refer to Chapter 5 for information about the I/O Image, using Logic
Command/Status, Reference/Feedback, and Datalinks.
About Explicit Messaging Explicit Messaging is used to transfer data that does not require
continuous updates. With Explicit Messaging, you can configure and
monitor a slave device’s parameters on the network.
TIP: To message to another device in a different drive port, refer to the

Instance table in Appendix C:
• DPI Parameter Object section on page C-12 for Device parameters.
• Host DPI Parameter Object section on page C-27 for Host

parameters.
In the Message Configuration screen, set the Instance field to an

appropriate value within the range listed for the port in which the device
resides.

6-2 Using Explicit Messaging
Performing Explicit There are five basic events in the Explicit Messaging process. The
Messages details of each step will vary depending on the type of controller being
used. Refer to the documentation for your controller.
Important: There must be a request message and a response message

for all Explicit Messages, whether you are reading or
writing data.
Figure 6.1 Explicit Message Process

➍ Message Response ➋ ➌
Event Description
You format the required data and set up the ladder logic program to send an
➊ Explicit Message request to the scanner module (download).
The scanner module transmits the Explicit Message Request to the slave
➋ device over the network.
The slave device transmits the Explicit Message Response back to the
➌ scanner. The data is stored in the scanner buffer.
The controller retrieves the Explicit Message Response from the scanner’s
➍ buffer (upload).
The Explicit Message is complete. Note: The scanner module may be
➎ integrated with the controller (for example, ControlLogix).
For information on the maximum number of Explicit Messages that can

be executed at a time, refer to the user manual for the scanner and/or
controller that is being used.

Using Explicit Messaging 6-3
ControlLogix Example
TIP: To display the Message Configuration screen in RSLogix 5000,
add a message instruction (MSG), create a new tag for the message
(Properties: Base tag type, MESSAGE data type, controller scope), and
click the button in the message instruction.
For supported classes, instances, and attributes, refer to Appendix C,

DeviceNet Objects.
Important: The explicit messaging examples in this section can be

performed using any firmware version of RSLogix 5000.

set the Data Type field to “INT.” Also, the Source Length field on the Message Configuration screen must correspond to the
selected Data Type in bytes (for example, 4 bytes for a REAL or a DINT, or 2 bytes for an INT). Refer to the drive
documentation to determine the size of the parameter.

(2)
Click Browse to find the path, or type in the name of the device listed in the I/O Configuration folder (for this example,
(3) In this example, we are reading five 32-bit REAL (floating point) parameters. Each parameter being read requires two contiguous
DINT registers. Therefore, a controller tag was created with its Data Type field set to “DINT[10].” Also, the Source Length field on
the Message Configuration screen must correspond to the selected Data Type in bytes (for this example, 40 bytes for a DINT[10]
array). Scattered read messages always assume that every parameter being read is a 32-bit parameter, regardless of its actual
size. Maximum message length is 128 bytes which can read up to 16 parameters, regardless of their size.
(4)
The controller tag for “Scattered_Read_Response” must be the same size as the controller tag for “Scattered_Read_Request.”

ControlLogix Example Scattered Read Request Data
In this example, we use the data structure in Figure 6.8 in the source tag
named Scattered Read Request to read these five 32-bit REAL (floating
point) parameters in a PowerFlex 750-Series drive: 001 - [Output
Frequency], 007 - [Output Current], 008 - [Output Voltage], 009 -
[Output Power], and 011 - [DC Bus Volts].

ControlLogix Example Scattered Read Response Data
The Scattered Read Request message reads the multiple parameters and
returns their values to the destination tag (Scattered_Read_Response).
Figure 6.9 shows the parameter values which, in this example, have
been converted using a UDDT for correct presentation. COP (Copy)
instructions could have been used for this purpose instead of a UDDT.

written with data received from the network. Reset Required: No
These are parameters written by the controller
(outputs from the controller).
If setting the value manually, the parameter
value = (10000 * port number ) + (destination
parameter number). For example, suppose you
want to use Host Parameter 01 - [DL From
Net 01] to write to Parameter 01 of an optional
encoder module plugged into drive Port 5. The
value for Host Parameter 01 - [DL From Net
01] would be 50001 [(10000 * 5) + 1].

18 FP Max Decimals Bit 2 to not limit the number of decimal places used.
19 FP Max Decimals Bit 1
20 Extended Parameter 0 = Not an Extended Parameter Reference
Reference 1 = Extended Parameter Reference
An Extended Parameter Reference contains a reference to another parameter.
The value is formatted the same as an analog mode Indirect Selector parameter
(SSpppp, where SS = slot number of device to which this Extended Parameter
Reference is pointing, and pppp = number of the parameter or diagnostic item to
which this Extended Parameter Reference is pointing). Note that an Extended
Parameter Reference can only select parameters unlike an Indirect Selector. An
Extended Parameter Reference could be used to configure a Datalink or show
the source of a Reference (among other uses).
21 Uses Rating Table Object This parameter has rating-dependent defaults and limits that can be obtained
from the Rating Table Object. The Offline Read Full will include the default value
for the smallest rating and limits that will accommodate the full range of values
allowed in the family of devices using this particular combination of Family Code
and Config Code. The Online Read Full will include the rating-dependent default
and limit values for this particular combination of Family Code, Config Code, and
Rating Code.
22 Writable Referenced This bit must be zero unless the parameter is an Extended Parameter
Parameter Reference. If the parameter is an Extended Parameter Reference, then:
0 = The referenced parameter may be read-only or writable.
1 = The referenced parameter must always be writable (including while running).
23 Disallow Zero This bit must be zero unless the parameter is an Indirect Selector or Extended
Parameter Reference. If the parameter is an Indirect Selector or Extended
Parameter Reference, then:
0 = Allow zero
1 = Disallow zero
If this bit is cleared (indicating that a value of zero is allowed), the device must
support the “Zero Text” parameter attribute so that a software tool or HIM can
obtain text from the Zero Text parameter attribute.
If this bit is set (indicating that a value of zero is disallowed), a software tool or
HIM will not allow the user to enter a value of zero.
24 Datalink Out This bit is used by offline tools and indicates that this is a Datalink Out
parameter. Bit 20 must also be set.
25 Datalink In This bit is used by offline tools and indicates that this is a Datalink In parameter.
Bits 20 and 22 must also be set.


26 Not Writable While IO Active This parameter cannot be written if the I/O data being exchanged between the
Host and the peripheral is valid.
27 Command Parameter This parameter commands the drive to take an action, such as “Reset Defaults”
or “Autotune,” and then returns to a value of zero. Offline software tools will not
allow setting this parameter to anything other than a value of zero. If an offline
file contains a Command Parameter with a non-zero value, the offline software
tool will change the value to zero. Note that command parameters cannot have
values that do not return to zero.
28 Current Value Is Default This bit identifies a parameter that will not change if a “Reset Defaults” is
commanded. For example, if a drive contains a Language parameter that is set
to German, setting defaults will leave the parameter set to German. Likewise, if
the parameter is set to French, setting defaults will leave the parameter set to
French.
29 Use Zero Text If the “Disallow Zero” bit is set, this bit must be cleared. If the “Disallow Zero” bit
is cleared, then:
0 = Use Disabled Text parameter class attribute.
1 = Use Zero Text parameter instance attribute.

17 FP Max Decimals Bit 1 number of decimal places to be displayed for small values. A value of 0 indicates
18 FP Max Decimals Bit 2 to not limit the number of decimal places used.
19 FP Max Decimals Bit 1
20 Extended Parameter 0 = Not an Extended Parameter Reference
Reference 1 = Extended Parameter Reference
An Extended Parameter Reference contains a reference to another parameter.
The value is formatted the same as an analog mode Indirect Selector parameter
(SSpppp, where SS = slot number of device to which this Extended Parameter
Reference is pointing, and pppp = number of the parameter or diagnostic item to
which this Extended Parameter Reference is pointing). Note that an Extended
Parameter Reference can only select parameters unlike an Indirect Selector. An
Extended Parameter Reference could be used to configure a Datalink or show
the source of a Reference (among other uses).
21 Uses Rating Table Object This parameter has rating-dependent defaults and limits that can be obtained
from the Rating Table Object. The Offline Read Full will include the default value
for the smallest rating and limits that will accommodate the full range of values
allowed in the family of devices using this particular combination of Family Code
and Config Code. The Online Read Full will include the rating-dependent default
and limit values for this particular combination of Family Code, Config Code, and
Rating Code.
22 Writable Referenced This bit must be zero unless the parameter is an Extended Parameter
Parameter Reference. If the parameter is an Extended Parameter Reference, then:
0 = The referenced parameter may be read-only or writable.
1 = The referenced parameter must always be writable (including while running).
23 Disallow Zero This bit must be zero unless the parameter is an Indirect Selector or Extended
Parameter Reference. If the parameter is an Indirect Selector or Extended
Parameter Reference, then:
0 = Allow zero
1 = Disallow zero
If this bit is cleared (indicating that a value of zero is allowed), the device must
support the “Zero Text” parameter attribute so that a software tool or HIM can
obtain text from the Zero Text parameter attribute.
If this bit is set (indicating that a value of zero is disallowed), a software tool or
HIM will not allow the user to enter a value of zero.
24 Datalink Out This bit is used by offline tools and indicates that this is a Datalink Out
parameter. Bit 20 must also be set.
25 Datalink In This bit is used by offline tools and indicates that this is a Datalink In parameter.
Bits 20 and 22 must also be set.


26 Not Writable While IO Active This parameter cannot be written if the I/O data being exchanged between the
Host and the peripheral is valid.
27 Command Parameter This parameter commands the drive to take an action, such as “Reset Defaults”
or “Autotune,” and then returns to a value of zero. Offline software tools will not
allow setting this parameter to anything other than a value of zero. If an offline
file contains a Command Parameter with a non-zero value, the offline software
tool will change the value to zero. Note that command parameters cannot have
values that do not return to zero.
28 Current Value Is Default This bit identifies a parameter that will not change if a “Reset Defaults” is
commanded. For example, if a drive contains a Language parameter that is set
to German, setting defaults will leave the parameter set to German. Likewise, if
the parameter is set to French, setting defaults will leave the parameter set to
French.
29 Use Zero Text If the “Disallow Zero” bit is set, this bit must be cleared. If the “Disallow Zero” bit
is cleared, then:
0 = Use Disabled Text parameter class attribute.
1 = Use Zero Text parameter instance attribute.

Glossary
A Automatic Device Replacement (ADR)

A means for replacing a malfunctioning device with a new unit, and
having the device configuration data set automatically. The DeviceNet
scanner is set up for ADR using RSNetWorx for DeviceNet. The
scanner uploads and stores a device’s configuration. Upon replacing a
malfunctioning device with a new unit (node 63), the scanner
automatically downloads the configuration data and sets the node
address.
B Bridge
A network device that can route messages from one network to another.
A bridge also refers to a communications module in a ControlLogix
controller that connects the controller to a network. See also scanner.
Bus Off
A bus off condition occurs when an abnormal rate of errors is detected
on the Control Area Network (CAN) bus in a device. The bus-off device
cannot receive or transmit messages on the network. This condition is
often caused by corruption of the network data signals due to noise or
data rate mismatch.
C CAN (Controller Area Network)

CAN is a serial bus protocol on which DPI is based.
Change of State (COS) I/O Data Exchange

A device that is configured for Change of State I/O data exchange
transmits data at a specified interval if its data remains unchanged. If its
data changes, the device immediately transmits the change. This type of
exchange can reduce network traffic and save resources since
unchanged data does not need to be transmitted or processed.
CIP (Common Industrial Protocol)

CIP is the transport and application layer protocol used for messaging
over EtherNet/IP, ControlNet, and DeviceNet networks. The protocol is
used for implicit messaging (real-time I/O) and explicit messaging
(configuration, data collection, and diagnostics).
Class
A class is defined by the DeviceNet specification as “a set of objects
that all represent the same kind of system component. A class is a
generalization of an object. All objects in a class are identical in form
and behavior, but may contain different attribute values.”
ControlFLASH
An Allen-Bradley software tool that lets users electronically update
firmware on printed circuit boards.

G-2 Glossary
Controller
A controller, also called programmable logic controller, is a solid-state
control system that has a user-programmable memory for storage of
instructions to implement specific functions such as I/O control, logic,
timing, counting, report generation, communication, arithmetic, and
data file manipulation. A controller consists of a central processor,
input/output interface, and memory. See also Scanner.
Cyclic I/O Data Exchange

A device configured for Cyclic I/O data exchange transmits data at a
user-configured interval. This type of exchange ensures that data is
updated at an appropriate rate for the application and allows data to be
sampled at precise intervals for better determinism.
D Data Rate
The speed at which data is transferred on the DeviceNet network. The
available data rates depend on the type of cable and total cable length
used on the network:
Maximum Cable Length

Cable 125kbps 250kbps 500kbps
Thick Trunk Line 500 m (1,640 ft.) 250 m (820 ft.) 100 m (328 ft.)
Thin Trunk Line 100 m (328 ft.) 100 m (328 ft.) 100 m (328 ft.)
Maximum Drop Length 6 m (20 ft.) 6 m (20 ft.) 6 m (20 ft.)
Cumulative Drop Length 156 m (512 ft.) 78 m (256 ft.) 39 m (128 ft.)
Each device on a DeviceNet network must be set for the same data rate.
You can set the DeviceNet Option Module to 125kbps, 250kbps, or
500kbps. You can set it to Autobaud if another device on the network
has set the data rate.
Datalinks
A Datalink is a type of pointer used by PowerFlex 750-Series drives to
transfer data to and from the controller. Datalinks allow specified
parameter value(s) to be accessed or changed without using explicit
messages. When active, each 32-bit Datalink in a PowerFlex 750-Series
drive consumes 4 bytes in the input image table and/or 4 bytes in the
output image table of the controller.
DeviceNet Network
An open producer/consumer Controller Area Network (CAN) which
connects devices (for example, controllers, drives, and motor starters).
Both I/O and explicit messages can be transmitted over the network. A
DeviceNet network can support a maximum of 64 devices. Each device
is assigned a unique node address and transmits data on the network at
the same data rate.
A cable is used to connect devices on the network. It contains both the

signal and power wires. Devices can be connected to the network with
drop lines, in a daisy-chain connection, or a combination of the two.

Glossary G-3
General information about DeviceNet and the DeviceNet specification

are maintained by the Open DeviceNet Vendor’s Association (ODVA).
ODVA is online at http://www.odva.org.
DriveExplorer Software
A tool for monitoring and configuring Allen-Bradley products and
network communication Option Modules. It can be run on computers
running various Microsoft Windows operating systems. DriveExplorer
(version 6.xx or higher) can be used to configure this Option Module
and PowerFlex drive. Information about DriveExplorer software and a
free lite version can be accessed at http://www.ab.com/drives/
driveexplorer.
DriveTools SP Software
A software suite designed for running on various Microsoft Windows
operating systems. This software suite provides a family of tools,
including DriveExecutive, that you can use to program, monitor,
control, troubleshoot, and maintain Allen-Bradley products. DriveTools
SP can be used with PowerFlex drives. Information about DriveTools
SP can be accessed at http://www.ab.com/drives/drivetools.
E EDS (Electronic Data Sheet) Files

Simple text files that are used by network configuration tools such as
RSNetWorx for DeviceNet to describe products so that you can easily
commission them on a network. EDS files describe a product device
type and revision. EDS files for many Allen-Bradley products can be
found at http://www.ab.com/networks/eds.
Explicit Messaging
Explicit messages are used to transfer data that does not require
continuous updates. They are typically used to configure, monitor, and
diagnose devices over the network.
F Fault Action
A fault action determines how the Option Module and connected drive
act when a communications fault (for example, a cable is disconnected)
occurs or when the controller is switched out of run mode. The former
uses a communications fault action, and the latter uses an idle fault
action.
Fault Configuration
When communications are disrupted (for example, a cable is
disconnected), the Option Module and PowerFlex drive can respond
with a user-defined fault configuration. The user sets the data that is
sent to the drive using specific fault configuration parameters in the
Option Module. When a fault action parameter is set to use the fault
configuration data and a fault occurs, the data from these parameters is
sent as the Logic Command, Reference, and/or Datalink(s).

G-4 Glossary
Faulted Node Recovery

This DeviceNet feature lets you change a configuration of a device that
is faulted on the network. For example, if you add a device to a network
and it does not have a unique address, it will fault. If you have a
configuration tool that supports faulted node recovery and your Option
Module is using parameters to set its node address and data rate, you
can change the node address.
Flash Update
The process of updating firmware in a device. The Option Module can
be flash updated using various Allen-Bradley software tools. Refer to
Flash Updating the Option Module on page 3-11 for more information.
H Heartbeat Rate
The heartbeat rate is used in Change of State (COS) data exchange. It is
associated with producing data once every EPR (Expected Packet Rate)
duration. There may be four heartbeats before a time-out happens.
HIM (Human Interface Module)

A device that can be used to configure and control a drive. Enhanced
PowerFlex 7-Class HIMs (for example, 20-HIM-A6) can be used to
configure PowerFlex 750-Series drives and their connected peripherals.
Hold Last
When communication is disrupted (for example, a cable is
disconnected), the Option Module and PowerFlex drive can respond by
holding last. Hold last results in the drive receiving the last data
received via the network connection before the disruption. If the drive
was running and using the Reference from the Option Module, it will
continue to run at the same Reference.
I Idle Action
An idle action determines how the Option Module and connected drive
act when the controller is switched out of run mode.
I/O Data
I/O data, sometimes called “ implicit messages” or “input/output,” is
time-critical data such as a Logic Command and Reference. The terms
“input” (To Net) and “output” (From Net) are defined from the
controller’s point of view. Output is produced by the controller and
consumed by the Option Module. Input is produced by the Option
Module and consumed by the controller.
L Logic Command/Logic Status

The Logic Command is used to control the PowerFlex 750-Series drive
(for example, start, stop, direction). It consists of one DINT or DWORD
of output from the network to the Option Module. The definitions of the
bits in this word are shown in Appendix D.

Glossary G-5
The Logic Status is used to monitor the PowerFlex 750-Series drive (for
example, operating state, motor direction). It consists of one DINT or
DWORD of input from the Option Module to the network. The
definitions of the bits in this word are shown in Appendix D.
M Master-Slave Hierarchy
An Option Module configured for a master-slave hierarchy exchanges
data with the master device. Usually, a network has one scanner which
is the master device, and all other devices (for example, drives with
installed DeviceNet Option Modules) are slave devices.
On a network with multiple scanners (called a multimaster hierarchy),

each slave device must have one scanner specified as a master.
N Node Address
A DeviceNet network can have as many as 64 devices connected to it.
Each device on the network must have a unique node address between 0
and 63. Node address 63 is the default used by uncommissioned
devices. Node addresses are sometimes called “MAC IDs.”
NVS (Non-Volatile Storage)

NVS is the permanent memory of a device. Devices such as the Option
Module and drive store parameters and other information in NVS so
that they are not lost when the device loses power. NVS is sometimes
called “EEPROM.”
O Option Module
Devices such as drives, controllers, and computers usually require a
network communication Option Module to provide a communication
interface between them and a network such as DeviceNet. An Option
Module reads data on the network and transmits it to the connected
device. It also reads data in the device and transmits it to the network.
The 20-750-DNET DeviceNet Option Module connects PowerFlex

750-Series drives to a DeviceNet network. Option Modules are
sometimes also called “adapters,” “cards,” “embedded communication
options,” and “peripherals.” On PowerFlex 750-Series drives, Option
Modules can also be I/O, encoders, safety, etc.
P PCCC (Programmable Controller Communications Command)

PCCC is the protocol used by some controllers to communicate with
devices on a network. Some software products (for example,
DriveExplorer and DriveExecutive) also use PCCC to communicate.
Ping
A message that is sent by a DPI product to its peripheral devices. They
use the ping to gather data about the product, including whether it can
receive messages and whether they can log in for control.

G-6 Glossary
Polled I/O Data Exchange

A device that is configured for polling I/O data exchange sends data
immediately after it receives a request for the data. For example, an
Option Module receives a Logic Command from the scanner and then
sends back the Logic Status of the connected PowerFlex drive.
PowerFlex 750-Series (Architecture Class) Drives

Allen-Bradley PowerFlex 750-Series drives are part of the PowerFlex
7-Class family of drives.
Producer/Consumer Network
On producer/consumer networks, packets are identified by content
rather than an explicit destination. If a node needs the packet, it will
accept the identifier and consume the packet. The source therefore
sends a packet once and all the nodes consume the same packet if they
need it. Data is produced once, regardless of the number of consumers.
Also, better synchronization than Master-Slave networks is possible
because data arrives at each node at the same time
R Reference/Feedback
The Reference is used to send a setpoint (for example, speed or
frequency) to the drive. It consists of one 32-bit REAL (floating point)
piece of output control data from the network to the Option Module.
Feedback is used to monitor the speed of the drive. It consists of one

32-bit REAL (floating point) piece of input control data from the
Option Module to the network.
RSLogix 5000
RSLogix 5000 software is a tool for configuring and monitoring
controllers to communicate with connected devices. It is an application
that runs on various Windows operating systems. Information about
RSLogix software can be found at http://www.software.rockwell.com/
rslogix.
S Scanner
A scanner is a separate module (of a multi-module controller) or a
built-in component (of a single-module controller) that provides
communication with Option Modules connected to a network. See also
Controller.
SI (Serial Interface)
A next generation communication interface used by various
Allen-Bradley drives, such as PowerFlex 750-Series drives.
Status Indicators
Status indicators are LEDs that are used to report the status of the
Option Module, network, and drive. They are on the Option Module and
can be viewed when the drive is powered and its cover is removed.

Glossary G-7
Stop Action
disconnected), the Option Module and drive can respond with a stop
action. A stop action results in the drive receiving zero as values for
Logic Command, Reference, and Datalink data. If the drive was running
and using the Reference from the Option Module, it will stay running
but at zero Reference.
U UCMM (UnConnected Message Manager)

UCMM provides a method to create connections between DeviceNet
devices.
UDDT (User-Defined Data Type)

A structure data type that you define during the development of an
application (for example, to convert 32-bit REAL parameter data for
written and read values to correctly display them in human readable
format).
Z Zero Data
disconnected), the Option Module and drive can respond with zero data.
Zero data results in the drive receiving zero as values for Logic
Command, Reference, and Datalink data. If the drive was running and
using the Reference from the Option Module, it will stay running but at
zero Reference.
