2.1 General description

The PC WORX SRT Software PLC is a PC hardware-based PLC with integrated PROFINET
and Modbus support. It can be used for simple automation tasks without hard realtime
requirements.

Supported hardware Valueline industrial PCs from Phoenix Contact (such as the VL BPC ..., see Section
“Ordering data” on page 68) offer optimum requirements for operating the Software PLC.

IEC 61131 control The PC WORX SRT Software PLC is consistently configured and programmed in
performance accordance with IEC 61131 using the PC Worx automation software. PC Worx can be
installed locally on the same PC as the Software PLC or on a separate PC. Programming in
all five IEC 61131 languages is supported.
The Software PLC can be used independently of the PC Worx software. For example, the
Software PLC and PC Worx can be installed on separate PCs. The Software PLC is
programmed via the network adapter which is assigned to the Software PLC. If the Software
PLC and PC Worx are installed on the same PC hardware, standard Windows mechanisms
are used for communication between these two applications, just like communication
between the Software PLC and the Windows operating system itself (see Figure 2-2 on
page 10).

For information on installing the PC Worx software, please refer to the quick start guide
for the software (see Section “Documentation” on page 69).

Integrated Ethernet The Software PLC can be assigned to one of the network adapters on the PC. It is used as
functionality/PROFINET an external Ethernet interface. The Software PLC can be programmed via Ethernet with the
help of this interface.
When using the AX OPC server provided in the AUTOMATIONWORX Software Suite
Version 1.81 or later, the Software PLC data is available in the Ethernet network in a
standardized format and can be used for the different visualization packages.
In a PROFINET network, the Software PLC can be used as a PROFINET controller or
PROFINET device. As a PROFINET controller the Software PLC supports up to eight
PROFINET devices depending on the type of PC used.

For additional information on PROFINET, please refer to the following documents (see
also Section “Documentation” on page 69):

of your Windows operating system.

4.6 Errors and troubleshooting

Requirements for correct operation of the Software PLC

Since the Software PLC does not offer realtime capability, there may be unforeseen
interactions with other software tools running under Windows on the PC or with Windows
itself. This behavior may disrupt correct operation of the Software PLC.
For stable and high-performance operation of the Software PLC, we recommend the
following:
– Select the PC in accordance with the system requirements (see Section “System
requirements” on page 7).
– Make sure that the power options for your PC are disabled or that correct operation
of the Software PLC is not affected by Windows switching to energy-saving mode.
– Make sure that as few additional software tools as possible are installed on the PC in
addition to the Software PLC and, if they are absolutely necessary, that as few
additional software tools as possible are executed at the same time as the Software
PLC.
The status monitor indicates any errors affecting the correct operation of the Software PLC
as shown in Figure 4-18.

After creating a new project, the project information is displayed in the bus configuration
workspace.
• Adapt the project information to your project.

Figure 5-7 Project information after creating a new project

First and last IP address, During project creation, PC Worx automatically assigns an IP address area for a local
subnet mask network (area from 192.168.0.2 to 192.168.0.254, see Figure 5-7 on page 46). If you would
like to use another address area (e.g., a global network), adapt the start and end address
on the project node (here: PCWORXSRT_UM).) to your application.

Observe the IP address settings of the network adapter

If necessary, adjust the IP address area in the project information according to the IP
address settings of the network adapter you selected when installing the Software PLC
(see “Selecting the network adapter/project directory” on page 16). For the address set in
the example (192.168.0.2), no further adjustment is required. It is in the subnet of the
default address area proposed by PC Worx.

46 PHOENIX CONTACT 8681_en_00

 Software PLC and PC Worx – program creation

If the IP parameters are modified in the project information, the IP address of the network
adapter that you assigned to the Software PLC during installation may have to be modified
manually (see Section “Assigning/checking the IP address for the Software PLC” on
page 48).

If you are using the addresses of a local network in your project, also assign a
corresponding address for the local network (e.g., 192.168.0.225) to the PC on which
PC Worx is installed. Otherwise the devices in the local network cannot be accessed.
For information on the IP addresses to be used within your system, please contact your
system administrator.
If the start address of the new address area to be entered is higher than the previous end
address, please modify the end address first.
If you manually assign IP parameters that are outside the defined area, they will be
accepted and displayed with a warning.

If you have installed the Software PLC and PC Worx on different PCs, the IP addresses of
the network adapter assigned to the Software PLC as well as the IP address area preset in
PC Worx must be in the same subnetwork.

PC/network adapter To determine whether your network permits the IP settings used in the example project (see
Figure 5-8 on page 48), proceed as follows:
• In the Windows Control Panel, check the settings for your PC network adapter.
• If necessary, adjust these settings so that the Software PLC can be accessed in your
network via the IP address used in the example project.
If your network does not permit the use of the IP address used in the example project, adjust
the settings in the project information accordingly (see Figure 5-8 on page 48).

If any modifications are made to the project information that affect the IP settings for the
controller, a warning is displayed. However, the modification is not implemented
automatically.

5.4 Assigning/checking the IP address for the

Software PLC

According to the IP address settings in the project information (see Section

“Checking/specifying project information” on page 46 and onwards), the IP address for the
Software PLC must be set in the device details in the “IP Settings” tab.
• Set the IP address “192.168.0.2” (see Figure 5-8).

This address is needed to ensure communication between PC Worx and the Software
PLC (e.g., for project download to the Software PLC) (see Section “General description”
on page 9 and onwards). This address entered in the project does not change the IP
address of the PC network adapter that was assigned to the Software PLC during
installation.
This interface is either used to download the PC Worx project to the Software PLC or to
connect the PROFINET devices to the Software PLC in the application. If required by your
application, this address must be adapted to your network.
Localhost function
The localhost function (see also “Localhost” on page 31) allows you to access the
Software PLC in PC Worx using the IP address “127.0.0.1”, e.g., for program download,
without having assigned an IP address to the Software PLC beforehand.

5.11 Function blocks for handling files in the

parameterization memory

The function blocks are used to access files from within the application program. Some of
the blocks support multiple instantiation. This means that it is possible to work with a number
of different files within the same project. The blocks perform the standard functions that are
required for typical file access operations.
The FILE_NOTIFY block is available in addition to the blocks for typical file access
operations. This block can be used to detect files that have been modified in a directory
containing user files. These modifications may include:
– Deletion of one or more files
– Writing one or more new files
– Modification of one or more existing files
Both modifications made to this directory via FTP (remote) and modifications made locally
via function blocks or firmware services can be detected.

All file operations are subject to the following restrictions:

No directory hierarchies are supported. All file operations only affect the root directory of
the parameterization memory.

The function blocks are valid for the PC WORX SRT Software PLC Version 1.0 or later.

Table 5-1 Overview of function blocks

Function block Short description
FILE_OPEN Opens a file with a specific name.
FILE_CLOSE Closes a file with a specific handle.
FILE_READ Reads from a file with a specific handle.
FILE_WRITE Writes to a file with a specific handle.
FILE_REMOVE Deletes a file with a specific name.
FILE_TELL Determines the current position of the file pointer in a file.
FILE_SEEK Moves the current file pointer to a new position.
FILE_NOTIFY Displays files that have recently been created, deleted or
modified.

6.4 PROFINET system variables

PROFINET provides extremely detailed diagnostic information from each device down to
the channel.
Diagnostic states are important for system operation. If error messages occur, the process
has to be stopped in case of doubt. To this end, AUTOMATIONWORX controllers provide
the following status information for the PROFINET network.
The table below describes the PROFINET system variables of the integrated PROFINET
controller function.

Table 6-4 PROFINET system variables (PROFINET controller function)

System variable Type Meaning
PNIO_SYSTEM_BF BOOL No connection to a configured PROFINET device
An error has occurred in the PROFINET network, i.e., a
connection could not be established to at least one configured
device. This value is not set if the “Control BF” parameter is set
to FALSE for a device. This device has therefore been excluded
from connection monitoring.
PNIO_SYSTEM_SF BOOL Diagnostic alarm on a configured PROFINET device
At least one PROFINET device is indicating a system error
(diagnostic alarm or maintenance alarm). The error priority can
be determined from the PNIO_DIAG_AVAILABLE,
PNIO_MAINTENANCE_DEMANDED, and
PNIO_MAINTENANCE_REQUIRED variables.
PNIO_DIAG_AVAILABLE BOOL Diagnostics available
At least one PROFINET device is indicating a diagnostic alarm
for an active connection. The corresponding device(s) can be
identified using the RALRM diagnostic block or by requesting the
diagnostic status byte of each PN_DA_NO_DIAG device.
The application must decide, for example, whether outputs of the
other PROFINET devices in the network may continue to be
operated.
PNIO_MAINTENANCE_DEMANDED BOOL Maintenance demanded – maintenance demand
At least one PROFINET device is indicating the “maintenance
demand” alarm (high-priority maintenance alarm) for the active
connection. The device can be identified using the RALRM
diagnostic block.
PNIO_MAINTENANCE_REQUIRED BOOL Maintenance required – maintenance requirement
At least one PROFINET device is indicating the “maintenance
requirement” alarm (low-priority maintenance alarm) for the
active connection. The device can be identified using the
RALRM diagnostic block.
PNIO_FORCE_FAILSAFE BOOL All PROFINET devices are prompted to set/assume their
configured substitute values.

Table 6-4 PROFINET system variables (PROFINET controller function)

System variable Type Meaning
PNIO_CONFIG_STATUS BOOL Connection establishment to the devices is active.
PNIO_CONFIG_STATUS_READY BOOL Connection establishment to the devices has been completed.
PNIO_CONFIG_STATUS_ACTIVE BOOL Communication started
The PROFINET controller configuration has been applied and
the PROFINET controller is started. Connection establishment is
active.
PNIO_CONFIG_STATUS_CFG_FAULT BOOL Configuration error
The PROFINETcontroller configuration has not been applied
due to a serious error and the PROFINET controller is not
started. Please contact Phoenix Contact.

If one of these values is set, it is now possible to decide from the program whether the
system should continue operating. For example, system errors such as maintenance
requirement and maintenance demand can only result in a message to service personnel,
which informs them of the location, cause, and urgency of the error.
The table below describes the PROFINET system variables of the integrated PROFINET
device function.

Table 6-5 PROFINET system variables (PROFINET device functionality)

active. The value is TRUE if the higher-level controller is in
the RUN state (program). The display only applies when
there is an existing PROFINET connection
(PND_S1S1_VALID_DATA_CYCLE).
PND_S1S1_VALID_DATA_CYCLE BOOL PROFINET controller has established the connection
Information indicating whether a connection exists and
cyclic data is being exchanged between the PROFINET
controller and PROFINET device and whether the last frame
received contained valid data (DATA_VALID_BIT).
PND_S1S1_OUTPUT_STATUS_GOOD BOOL IOP status of the higher-level controller
Information indicating whether the IN process data of the
PROFINET device (PNS_S1S1_INPUTS) was received by
the PROFINET device with “valid” status. The value is TRUE
if the output data of the higher-level controller is valid
(provider status).
PND_S1S1_INPUT_STATUS_GOOD BOOL IOC status of the higher-level controller
Information indicating whether the OUT process data of the
PROFINET device (PNS_S1S1_OUTPUTS) was received
by the PROFINET controller with “valid” status. The value is
TRUE if the input data of the higher-level controller has been
processed (consumer status).
