Introduction Section 1
Overview
human system interface (HSI) access to Control Network
(Cnet) in the Symphony Enterprise Management and Control
System.
NOTE: The INICI12 interface is fully compatible with existing INFI 90 OPEN
Strategic Enterprise Management Systems using the INFI-NET communication
system.
The INICI12 interface mainly consists of the INNIS01 Network
Interface Module and the INICT12 Computer Transfer Module
(Fig. 1-1). This interface gives a host computer access to point
data over Cnet along with other control system capabilities. It
supports a tag database capacity of 10,000 tags (i.e., point def-
initions). The computer connects through an RS-232-C serial
port that operates at rates up to 19.2 kilobaud. The interface
is command driven through software on the host computer. It
receives a command from the host computer, executes it, then
replies.

Overview
Control Network
Cnet is a unidirectional, high speed serial data network that
operates at a 10-megahertz or two-megahertz communication
rate. It supports a central network with up to 250 system node
connections. Multiple satellite Cnets can link to the central
network. Each satellite network supports up to 250 system
node connections. Interfacing a maximum number of satellite
networks gives a system capacity of over 62,000 nodes.
On the central network, a node can be a satellite network, a

human system interface, a Harmony control unit (HCU), or a
computer connected through a Cnet communication interface.
On a satellite network, a node can be a human system inter-
face, an HCU cabinet, or a computer. A human system inter-
face is a workstation that runs Conductor software. A
Harmony control unit is comprised of a controller and its I/O
devices. A computer can run Composer™ tools, Performer
applications, and third-party semAPI applications.
Cnet is used by system nodes to:
• Communicate field input values and states for process

monitoring and control.
• Send or receive control instructions from plant personnel

through human system interfaces to adjust process field
outputs.
• Provide feedback to plant personnel of actual output
changes through human system interfaces.
• Communicate controller function block configuration

information and parameters. These parameters determine
the operation of functions such as process control, data
acquisition, alarming, trending, and logging.
• Report status.
• Download firmware.
Data is transferred in messages that contain system data, con-

trol, and configuration information and also in exception
reports.
1-2 WBPEEUI250021A0
Intended User
Computer
A computer can access Cnet for data acquisition, system con-
figuration, and process control. It connects to Cnet through
the Cnet-to-computer interface. This capability enables plant
personnel, for example, to develop and maintain control con-
figurations, manage the system database, and create HSI dis-
plays remotely using Composer tools. There are additional
Composer and Performer series tools and applications that
can access plant information through the computer interface.
Human System Interface

A human system interface such as a workstation running
Conductor software provides the ability to monitor and control
plant operations from a single point. It connects to Cnet
through the Cnet-to-computer interface. The number of work-
stations in a Symphony system varies and depends on the
overall control plan and size of a plant. The workstation con-
nection to Cnet gives plant personnel access to dynamic
plant-wide process information, and enables monitoring, tun-
ing, and control of an entire plant process from workstation
color graphics displays and the keyboard. Each HSI worksta-
tion has a dedicated computer interface.
NOTE: A workstation running Conductor NT software can interface to Cnet
through an INICI12 interface. A workstation running Conductor VMS does not
use the INICI12 interface but instead has its own dedicated version of the
Cnet-to-computer interface (IIMCP02 and IIMLM01).
Intended User
Personnel installing, operating, or maintaining the INICI12
interface should read this instruction before performing any
installation, operation, or maintenance procedures. Installa-
tion requires an engineer or technician with experience han-
dling electronic circuitry and familiarity with communication
networks.
Features

INNIS01 Network Interface

The INNIS01 Network Interface Module is the front end of
every Cnet communication interface. It is the intelligent link
between a node and the Cnet. In this case, it works in conjunc-
tion with the INICT12 module. The INNIS01 module allows any
node to communicate with any other node within the Sym-
phony system.
WBPEEUI250021A0 2-1
The INNIS01 module is a single printed circuit board that

occupies one slot in a module mounting unit (MMU). The cir-
cuit board contains microprocessor based communication cir-
cuitry that enables it to interface with Cnet, and with the
INICT12 module over a dedicated I/O expander bus segment.
Two latching screws on the faceplate secure the INNIS01 mod-

ule to the module mounting unit (Fig. 2-2). There are 16 LEDs
on the faceplate that display event or error counts and error
codes.

Figure 2-2. INNIS01 Module and NTCL01 Termination Unit
The INNIS01 module has three card edge connectors for exter-
nal signals and power (P1, P2, and P3). P1 connects to com-
mon and +5, +15, and -15 VDC power. P2 connects the
INNIS01 module to the I/O expander bus to communicate with
its INICT12 module. P3 connects the module to its NTCL01
communication termination unit.
Communication between Cnet nodes is through coaxial or twi-

naxial cable that connects between the termination units of
each node. An NTCL01 unit provides the redundant Cnet con-
nection points for the INICI12 interface node (coaxial J1
through J4 or twinaxial TB1 and TB2). The INNIS01 module
connects to the NTCL01 unit through an NKLS01 or NKLS11
cable attached between its P3 connector and P1 on the termi-
nation unit. The termination unit provides isolation circuitry
for Cnet.
Block Diagram
Figure 2-3 is a functional block diagram of the INNIS01 mod-
ule. The module contains a central processing unit (CPU),
memory, I/O expander bus interface, and a Cnet interface that
supports redundant Cnet (loop one and loop two).
2-2 WBPEEUI250021A0
CPU
The CPU contains a 32-bit microprocessor running at 10
megahertz and associated support circuitry (i.e., control logic,
address decoder, buffer control, etc.). The CPU interprets and
executes instructions to control communication and run diag-
nostics. Since the microprocessor is responsible for overall
module operation, it communicates with all the functional
blocks.

Cnet
The INNIS01 module handles all Cnet communication for the
INICI12 interface. This includes transmitting Cnet messages
originated from the node, receiving messages intended for the
node, and forwarding Cnet messages destined for other Cnet
nodes. The Cnet interface contains a transceiver, loop one and
loop two transmit drivers, and loop one and loop two receivers.
The INNIS01 module has the ability to isolate itself from Cnet
in the event of a component failure or to perform diagnostics.
NOTE: The INNIS01 module supports INFI-NET communication in existing
INFI 90 OPEN systems.
Receive On the receive side, the module has two independent channels
with separate memory for each channel to temporarily store
incoming messages. Messages are received on both channels
simultaneously and stored. The data is automatically checked
for integrity and various data protocol errors. If a message is
WBPEEUI250021A0 2-3
intended for the node, it is stored. If a message is intended for

another Cnet node, it is passed to the transmit side.
Transmit On the transmit side the module has one transmitter but two
independent transmit driver circuits. Messages originated by
the node and forwarded messages are transmitted on both
channels. Messages are first checked and formatted by the
CPU before they are transmitted. Messages are transmitted
using a transmit/acknowledge sequence.
Memory
The INNIS01 module memory consists of ROM memory and
static-RAM (SRAM) memory. The ROM memory holds the oper-
ating system instructions for the microprocessor (i.e., firm-
ware). SRAM memory provides temporary storage for the CPU.
The Cnet and I/O expander bus interfaces also use a portion
of the SRAM memory to store received messages and messages
to be transmitted.
I/O Expander Bus

The I/O expander bus is an eight-bit parallel bus that provides
the communication path for data between the INNIS01 module
and the INICT12 module. The I/O expander bus interface is
implemented using a custom integrated circuit utilizing an
ABB Automation designed communications protocol. This
interface provides the following functions:
• Address comparison and detection.

• Read strobe generation.
• Data line filtering of bus signals.
• On-board bus drivers.
The I/O expander bus used by the INICI12 interface is isolated

from any other rack modules.
NOTE: I/O expander bus is strictly used for internal cabinet communication.
Switches and LEDs

The CPU reads one of several internal event and error counters
and writes count data to data latches to control the front panel
LEDs. It reads switches SW1 through SW4 through data buff-
ers to determine its operating mode and operating addresses.
2-4 WBPEEUI250021A0
Operation
The INNIS01 module is the communication front end for the
computer interface. This section provides an overview of its
operating theory.
Exception Reports
Exception reported data is available to all Cnet nodes. Har-
mony nodes exception report data on Cnet automatically. A
controller, for example, generates an exception report periodi-
cally to update data, after a process point reaches a defined
alarm limit or changes state, or after a significant change in
value occurs. An exception reporting route must be estab-
lished, however, for the node to begin acquiring the exception
reported data. The data typically appears as dynamic values,
alarms, and state changes on displays and in reports gener-
ated by human system interfaces and other system nodes.
Exception reports can have data values in the following for-

mats: digital, analog, and status. Exception reports are
time-stamped to reflect their processing sequence. Some
examples of information contained in exception report param-
eters include:
• Analog process value.
• Alarm level.
• Deviation (rate of change).
• Digital process state.
• Alarm state.
• Quality.
A function block address is included in each exception report

to identify the source of the report. The address is a loop,
node, module, and block number.
Maximum and minimum report time parameters insure that

an exception report is generated for static data and limit
reports for rapidly changing data. The minimum report time
parameter controls the quantity of exception reports a single
rapidly changing point generates. The maximum report time
parameter generates a periodic report of data items that do not
change.
The host computer can source exception reports. The INICT12

module packages together exception reports having a common
WBPEEUI250021A0 2-5
node destination. Packing places all exception reports for a

destination (or multiple destinations) into one message. The
INNIS01 module then sends them to other Cnet nodes as a
single message. This process reduces the number of transmis-
sions required, and adjusts the message size for maximum
Cnet efficiency.
NOTE: If a point goes into or out of alarm, the time parameters are ignored and
the value is reported immediately. Minimum and maximum exception report
times are set through FC 82.
Messages
The INNIS01 module processes four different message types.
They are broadcast, time-synchronization, multicast, and NIS
poll.
Broadcast. A node generates a broadcast message when sending

information to all system nodes. Typically, these messages
announce changes in node status. Broadcast messages
include:
• Node online.
• Node offline.
• Node restart.
• Node busy.
Time-Synchronization. The time-synchronization message is a high
priority broadcast type of message. The INNIS01 module ser-
vices this message type immediately. Time-synchronization
provides a common system time base to be used for sequenc-
ing exception reports, accessing trend data, and display on a
human system interface such as a workstation running Con-
ductor software.
Multicast. A message that contains data for multiple destinations

is a multicast message. This message can have from one to 64
destinations.
NIS Poll. The NIS poll message is a single destination message.

The INNIS01 module uses this message type to request the
operational status of another node.
Message Format. Messages exist as frames of information. Each
frame consists of a message control field that follows an infor-
mation field. The information field contains the message data.
It can consist of multiple messages and vary in size to a
2-6 WBPEEUI250021A0
maximum of 1,500 bytes. The control field contains time of

origination, sequence, source, size, circulation count, message
type, destinations, and checksum.
The INNIS01 module increments the circulation count field of

all incoming messages. When a message count field exceeds
255, the message is discarded. This is useful in keeping retry
and spurious message traffic to a minimum. The INNIS01
module uses the message type to determine how to process the
message. The checksum and cyclic redundancy check code
fields verify data integrity.
Message Transmission. Any INNIS01 module can transmit a mes-

sage at any time without regard to the activities of any other
INNIS01 module on the Cnet. Each INNIS01 module can trans-
mit and receive messages simultaneously. Startup and shut-
down is local and requires no interaction with other INNIS01
modules on the network. Each module receives all incoming
messages and transmits a new stream of messages in a store
and forward fashion to the next node. When there are no mes-
sages for the INNIS01 module to transmit, the module trans-
mits flag characters (null packets) as the loop synchronizing
condition to keep the receivers in lock.
Data Integrity
There are three methods by which the INNIS01 module insures
data integrity. They are retry logic, node status table, and
polling.
Retry Logic. If, on the first transmission of a message, the

INNIS01 module does not receive positive acknowledgment
from the destination node, it retransmits the message 11
times. If after this series of retries there is still no response,
the destination node is marked offline.
Node Status Table. The INNIS01 module maintains an internal
table of system wide node status such as offline and busy. The
INNIS01 module relays node status changes to the INICT12
module. When the INNIS01 module periodically polls nodes, it
updates this table accordingly.
Polling. The INNIS01 module uses the information in its status

table for polling purposes. As it scans the status table, it picks
out destinations targeted for multicast messages that have
been marked offline or busy. After polling the destination, the
WBPEEUI250021A0 2-7
INICT12 Computer Transfer
INNIS01 module updates its table and forwards pertinent

information to the INICT12 module.
Power System Status

The communication system provides a means to monitor the
status of the power system of each node. This status informa-
tion can be displayed on a human system interface. Electron-
ics within the power entry panel monitor the power system
status. A single status output is made available to the commu-
nication system. To use this feature, wire the status output to
the terminal block on the NTCL01 termination unit labeled
PSS1 or PSS2. Two sets of terminals are available on the ter-
mination unit for interconnecting the power system status
output.
This power system status signal is fed through the termination

unit cable to the P3 connector on the INNIS01 module. The
power system status input is a TTL-compatible signal. A high
voltage level (5 VDC) on power system status indicates good
status. A low voltage level (0 VDC) indicates bad status. When
no connection is made to either of the power system status
inputs, a pull-up resistor on the INNIS01 module causes a
high level signal on the power system status input, thereby
reporting good status.

The INICT12 Computer Transfer Module handles all communi-
cation with a host computer. The module is a single printed
circuit board that occupies one slot in a module mounting
unit. The circuit board contains communication circuitry that
enables it to directly communicate with its INNIS01 module
over a dedicated I/O expander bus.
Two latching screws on the faceplate secure the INICT12 mod-

ule to the module mounting unit (Fig. 2-4). There are nine
LEDs on the faceplate and a stop/reset pushbutton.
The INICT12 module has three card edge connectors for exter-
nal signals and power (P1, P2, and P3). Connector P1 connects
to common, +5 VDC power. Connector P2 connects the
INICT12 module to the I/O expander bus to communicate with
its INNIS01 module. P3 connects the module to its NTMP01
Multifunction Processor termination unit.

Figure 2-4. INICT12 Module and NTMP01 Termination Unit
The INICT12 module supports RS-232-C protocol for computer

interface. An NTMP01 termination unit provides two RS-232-C
ports: port zero (P5) is normally for computer connection and
port one (P6) is normally for diagnostic terminal or security
key connection. Diagnostic port or security key capability
must first be enabled for the INICT12 module (SW4). Control
and data signals connect to the INICT12 module through a
NKTU01 or NKTU11 cable attached between its P3 connector
and P1 of the NTMP01 termination unit.
When communicating through the RS-232-C ports, the

INICT12 module can support either data terminal equipment
(DTE) or data communication equipment (DCE). The NTMP01
unit has jumpers to configure DTE or DCE operation. The ter-
mination unit provides optical isolation for the RS-232-C
ports.
Block Diagram
Figure 2-5 is a functional block diagram of the INICT12 mod-
ule. The module primarily contains a central processing unit
(CPU), memory, and I/O expander bus and RS-232-C serial
channel interfaces. Refer to I/O Expander Bus previously in
this section for an explanation of the I/O expander bus inter-
face.
CPU
The CPU contains a 32-bit microprocessor running at
16 megahertz and associated support circuitry (i.e., control

logic, address decoder, interrupt interface, system timer, etc.).

The CPU interprets and executes instructions to perform its
computer interface functions, control communication, and run
diagnostics. Since the microprocessor is responsible for overall
module operation, it communicates with all the functional
blocks.
Memory
The INICT12 module memory consists of ROM memory, SRAM
memory, and nonvolatile-RAM (NVRAM) memory. The ROM
memory holds the operating system instructions for the micro-
processor (i.e., firmware). The SRAM memory provides tempo-
rary storage and a copy of the point definition database. The
NVRAM memory holds the point definition database. The infor-
mation stored in NVRAM is retained when power is lost.
RS-232-C Serial Channels

The INICT12 module contains two independent RS-232-C
serial channels (A and B). These channels are connected to
port zero and port one of the NTMP01 termination unit. The
module uses a dual universal asynchronous receiver/trans-
mitter (DUART) circuit to direct data transfer through the
serial channels. Each channel supports standard baud rates
up to 19.2 kilobaud.
2 - 10 WBPEEUI250021A0
The termination unit provides optical isolation for each of the

channels. The isolation eliminates the need to tie chassis
ground to system common and alleviates the potential of dam-
age from ground currents.
Machine Fault Timer

The machine fault timer (MFT) is a security feature built into
the INICT12 module. The timer is a one-shot timer that must
be periodically reset by the CPU to prevent it from timing out.
If an error condition exists that causes the module to fail or
operate incorrectly, the timer will not be reset and will cause a
time-out condition. A time-out condition triggers a reset signal
to shut down the module.
The module performs a series of on-line diagnostics to verify

circuit integrity. A detected hardware failure may cause a
time-out condition. If the cause of the problem is not a hard-
ware failure, the module and timer can be reset by the
stop/reset pushbutton accessed through the front panel.
Stop/Reset
Control logic determines the stop/reset pushbutton (SW1)
operation. The pushbutton is used to halt the module opera-
tion and to reset the module. It is accessible through a small
hole in the front panel. Pressing the pushbutton once causes
the module to perform an orderly shutdown. Pressing the
pushbutton a second time resets the module.
Switches and LEDs

To control the front panel, the CPU writes data to latches con-
nected to the CPU LEDs (LEDs one through eight) and the sta-
tus LED. This data includes operating status, command/reply
count, and error codes. The CPU reads switches SW3 and SW4
through data buffers to determine its operating mode and
RS-232-C serial port operating characteristics.
Operation
The INICT12 module communicates with the host computer
using RS-232-C protocol. The module can store up to 10,000
point definitions (i.e., tags) depending on point type. The mod-
ule is command driven through software on the host com-
puter. It receives and interprets commands, executes the
WBPEEUI250021A0 2 - 11
Host Computer
commands, then replies. The module maintains the point

database, and directs all interaction between the host com-
puter and the Cnet. The INICT12 module firmware enables the
host computer to issue commands for data acquisition, pro-
cess monitoring and control, and to perform system functions
such as security, time-synchronization, status monitoring,
and configuration control.
The INNIS01 module receives data frames from the Cnet and
passes them on to the INICT12 module for processing. The
INICT12 module sorts this incoming data, storing exception
reports and incoming requests until the host computer is
ready for the data. This buffering action allows the host com-
puter to operate completely asynchronously to the Cnet. When
the host computer is ready to process more data, it issues a
command to the INICT12 module that forwards the data as a
reply.
Host Computer
The host computer connects to the INICI12 interface from its
RS-232-C port to an RS-232-C port of the NTMP01 termina-
tion unit. Two RS-232-C ports are located on the termination
unit. The computer normally connects to port zero.
Computer Interface Commands

The INICT12 module receives a command from a host com-
puter, performs the desired action, and then replies to the host
computer. The computer interface uses numerous commands
for data acquisition, process monitoring and control, and sys-
tem functions (i.e., security, time, and configuration control).
These commands fall into four basic command types: data
acquisition, configuration, process control, and system status.
The host computer uses establish point and establish report

commands to create the database in the INICT12 module. The
module has the capacity to store 10,000 point definitions
depending on the point type. The host computer has access to
the module database through data acquisition commands.
2 - 12 WBPEEUI250021A0
Computer Interface Commands
Data Acquisition
The host computer uses data acquisition commands to acquire
process data and system data from controllers in the Sym-
phony system. This includes point data, exception reported
data, trend data, module status, and performance statistics
for example.
Configuration
The host computer uses configuration commands to define,
modify, and view the function block configurations in control-
lers:
• Download function block configuration.
• Tune function block specifications. Tuning is the process

of changing certain function code specifications while the
controller is online or executing.
• Read function block outputs.
Process Control
The host computer uses process control commands to handle
analog and digital process requirements:
• Change process values: set point, control output, and ratio

index.
• Set digital switches.

• Define constants.
• Output values in exception reports.
System
Time-synchronization is a critical function of the computer
interface and part of overall status. It enables the host com-
puter to set and display system time and date, and provides a
mechanism for relating the time-stamp to system time and
date. The host computer is able to monitor individual module
status and system performance, and provide password protec-
tion.

Mounting Hardware
Mounting Hardware
Harmony rack modules and termination units mount in stan-
dard ABB Automation enclosures (CAB-01, CAB-04, CAB-12).
The number of modules that can be mounted in a single cabi-
net varies.
An IEMMU11, IEMMU12, IEMMU21, or IEMMU22 module

mounting unit and an NFTP01 field termination panel (FTP)
are used for module and termination unit mounting respec-
tively (Fig. 2-6). The mounting unit and termination panel both
attach to the side rails in standard 483-millimeter (19-inch)
enclosures. Front mount and rear mount MMU versions are
available to provide flexibility in enclosure mounting.
A module mounting unit is required to mount and provide

power to rack modules. The unit is for mounting controllers,
I/O modules, and communication interface modules. The
MMU backplane connects and routes:
• Controlway.
• I/O expander bus.
• Logic power to control, I/O, and interface modules.
The Controlway and I/O expander bus are internal cabinet,

communication buses. Communication between rack control-
lers and communication interface modules is over Controlway.

Operating Procedures Section 4
Introduction
After completing the steps detailed in the installation section,
the modules of the INICI12 interface are ready to be put into
operation. This section provides the necessary information for
daily operation of the modules.

Figure 4-1 shows the INNIS01 module faceplate. On power up,
the INNIS01 module microprocessor stays in reset until the
INICT12 module removes the reset and allows the firmware to
execute self-diagnostic routines. The INICT12 module deter-
mines when the INNIS01 module will go online. The INNIS01
module comes online in the network mode set by switch SW3,
with the type of counter display set by switch SW4.
Group A and B LEDs

Use the faceplate group A and B LEDs to check the INNIS01
module operation. If communication errors occur, the host
module sets the INNIS01 module communication status bits in
the module status. View the module status by using a human
system interface.
Event Counters
Internal counters maintain a count of events such as the num-
ber of messages transmitted, retries, and number of messages
lost. The group A and B LEDs on the module faceplate display
a binary value of the event counter selected with switch SW4.
LED B8 is the most significant bit; LED A1 is the least signifi-
cant bit. Refer to Table PR6-5 for a list of event types and their
counter addresses.
Error Counters
Errors such as receive errors, transmit errors, and dumped
messages are maintained in internal counters like events are.

CPU LEDs
During normal operation the eight CPU LEDs keep a count of
the commands and replies that pass through the INICT12
module. If an error occurs, these LEDs display an error code
and the status LED turns red. Refer to Table 5-2 for a list of
CPU LED error codes and associated corrective actions.
WBPEEUI250021A0 4-3
Stop/Reset
The stop/reset button is used to interrupt module execution
and to initiate a hardware reset. The button is accessed
through the small opening on the faceplate. Some type of thin
rod, preferably nonmetallic, is required to press the button.
First Press Press the button once to halt operation. The electronics con-
Stop duct an orderly shutdown after stop is initiated then turn the
status LED on red. Wait for the status LED to turn red before
removing the INICT12 module (or the INNIS01 module) from
the module mounting unit.
Second Press Press the button a second time to initiate a hardware reset. A
Reset hardware reset is required to recover from a module time-out
or a manual stop (single press). This also restores the module
to power up values.
NOTE: If the module has already stopped due to an error (i.e., status LED on
red), a single press resets the module.
Operating Modes
The INICT12 module has two modes of operation: execute and
error.
Execute
Execute mode is the normal mode of operation. In this mode
the INICT12 module performs its computer interface functions
as described in Section 2 giving the host computer access to
Cnet and Cnet nodes. The interface firmware permits the con-
figuration of the interface from the host computer.
Error
The INICT12 module enters error mode if the internal system
diagnostic routines detect a hardware or execution error. If the
module detects an error, the module halts and displays an
error code on the CPU LEDs. Refer to Section 5 for corrective
actions.
Module Integrity
All communication modules have normal Symphony system
security functions that insure module integrity. The INICT12
4-4 WBPEEUI250021A0
Utilities
module performs both hardware and software security checks

to insure module integrity.
Hardware Checks
The INICT12 module performs the following hardware checks:
Illegal Address Detecting an illegal address generates a bus error and the
Detection module halts operation. It also displays an error code on the
faceplate LEDs.
Machine Fault Timer The microprocessor updates the machine fault timer. If the
microprocessor fails to reset the MFT timer, it expires. When a
time-out occurs, the module stops and the status LED turns
red.
Software Checks
The INICT12 module performs the following software checks:
Module Diagnostics The module diagnostic routines execute automatically on sys-
tem power up. If the diagnostic tests fail, the faceplate LEDs
display error conditions, the status LED turns on red, and the
module operation halts.
ROM Checksum The ROM checksum test verifies checksums of the ROM mem-
ory. Discrepancies cause the module status LED to go solid red
and the module operation halts.
Utilities
The computer interface utilities are available by attaching a
computer or diagnostic terminal to port one of the NTMP01 ter-
mination unit. Enable the utilities with the INICT12 module
switch SW4 (Table PR7-1). The following utility options are

Troubleshooting Section 5
Introduction
This section provides troubleshooting information necessary to
isolate INICI12 interface errors. It is not meant to be all inclu-
sive. If a problem exists that cannot be corrected using the
information provided in this instruction, contact a local ABB
service office for assistance.
Troubleshooting Procedures
Troubleshooting the INICI12 interface is limited to deciphering
module LED error codes and viewing the contents of the error
counters and the module status report from any human sys-
tem interface (HSI). Refer to the instruction for the specific HSI
workstation being used for information on module status
reports.
Error Codes
All Cnet communication modules have faceplate LEDs that
serve as error code displays. The INNIS01 module has event
and error counters that are selectable.
INNIS01
The INNIS01 module error counters total errors in the same
manner as the event counters total events. Table PR6-6 lists
the types of error counters. The module halts operation if a
fatal error condition occurs. Group A LEDs on the module
faceplate display error codes. Group B LEDs are off when
group A LEDs are displaying any error code. Refer to Table 5-1
for a list of error codes and associated corrective actions.
INICT12

plays error codes only when it is halted.
A code that is not on the list may appear if a machine fault

time-out occurs. Reset the INICT12 module if this happens.
The module has failed if the status LED remains red. Replace
the module in this case.
Diagnostics
The firmware of the INICT12 and INNIS01 modules contain
various diagnostic routines used to verify proper operation of
components and circuitry. Some are run automatically during
startup and normal operation (online), and others can be
invoked manually (offline). If any of the online checks detect a
hardware problem, the module will provide error status code
indications (if possible) and will halt. Refer to Tables 5-1 and
5-2 to decipher the status codes.
The offline tests can be run to verify operation of a suspect

INICT12 module or to check module integrity before putting
the module into operation. The offline diagnostics should only
be run during installation or when the system is down. Refer
to procedure section PR16 for the steps to run offline diagnos-
tics. Putting the INICT12 module into diagnostic mode allows
the module to perform a variety of diagnostic tests but sus-
pends normal operation.
INICT12 Status Summary

The INICT12 module has a 16-byte module status record that
provides summary flags for error conditions, module type, and
firmware revision level. Table 5-3 lists the fields that make up
the INICT12 module status report and Table 5-4 describes
each field within the module status record.
WBPEEUI250021A0 5-3
The status report can be viewed from a human system inter-

face. To interpret the status bytes:
1. Convert each hexadecimal byte to its binary equivalent.

For example:
Byte 1 0x75 = 01110101
Refer to Tables 5-3 and 5-4 and for an explanation of each byte
and data bit.
Bit 7 0 = no errors.
Bit 6/5 11 = execute mode.
Bit 4-0 10101 = enhanced node type; reference

Maintenance Section 6
Introduction
The reliability of any stand-alone product or control system is
affected by the maintenance of the equipment. ABB Automa-
tion recommends that all equipment users practice a preven-
tive maintenance program that will keep the equipment
operating at an optimum level.
This section presents procedures that can be performed

on-site. These preventive maintenance procedures should be
used as guidelines to assist in establishing good preventive
maintenance practices. Select the minimum steps required to
meet the cleaning needs of your system.
Personnel responsible for maintenance should be familiar with

the Harmony rack modules, have experience working with pro-
cess control systems, and know what precautions to take when
working on live AC systems.
Preventive Maintenance Schedule

Table 6-1 is the preventive maintenance schedule for the
INICI12 interface modules. The table lists the preventive main-
tenance tasks in groups according to their specified mainte-
nance interval. Some tasks in Table 6-1 are intuitive or self
explanatory. Instructions for tasks that require further expla-
nation are covered in the indicated procedure section.
NOTE: The preventive maintenance schedule is for general purposes only.

Your application may require special attention.

Repair and Replacement Section 7
Introduction
This section explains repair and replacement procedures for
INICI12 interface.
Repair
INICI12 interface repair is limited to assembly replacement. If
a module or termination unit fails, remove and replace it with
another. Do not attempt to replace discrete components in any
Harmony device.
Replacement
Verify the main power, field power, and power entry panel cir-
cuit breakers/switches are turned off before starting the termi-
nation unit removal procedure. Failure to do so could result in
severe or fatal shock. Do not turn the power on until the
WARNING replacement procedure is complete.

unless the area is known to be nonhazardous.
The replacement procedures for most parts and assemblies are

intuitive. Figure 7-1 is the INICI12 interface replacement flow-
chart, which contains replacement procedures for those parts
and assemblies that need explanation.
In the flowchart, each flowchart block represents a single task.

The PR code in the flowchart block identifies the procedure
section that describes the steps to complete the indicated task.
Some steps are self-explanatory and have no related procedure
section. Complete all steps given in a procedure section before
continuing to the next flowchart block. The procedure sections
are located towards the back of the instruction.

boards (i.e., module and termination unit boards).
Parts None.
Tools • Clean, dry, filtered compressed air.
• Antistatic vacuum.
• Isopropyl alcohol (99.5 percent electronic grade).
• Foam-tipped swab.
• Distilled water.
• Nonabrasive eraser.
• Fiberglass or nylon burnishing brush.
• Piece of scrap printed circuit board.
• Soft lint-free cloths.
There are several cleaning procedures described. Use the pro-

cedures that meet the needs of the particular printed circuit
board to remove all dust, dirt, oil, corrosion, or any other con-
taminants from the board.
Perform all cleaning and handling of the printed circuit boards

at static safe workstations. Always observe electrostatic sensi-
tive device handling precautions when handling printed circuit
boards.
1. Wear eye protection whenever working with cleaning sol-

vents. When removing solvents from printed circuit boards
WARNING
using compressed air, injury to the eyes could result from
splashing solvent as it is blown off the printed circuit board.
General Cleaning and Washing
General Cleaning and Washing

□ 1. Remove dust and residue from the printed circuit board
surface using clean, dry, filtered compressed air or an anti-
static field service vacuum.
- or -
□ 1. Spray or wipe the printed circuit board with isopropyl alco-

W1 hol (99.5% electronic grade).
□ 2. Use a foam-tipped swab to wipe the printed circuit board.
□ 3. When the printed circuit board is clean, remove excess sol-

vent using clean, dry, filtered compressed air.
Edge Connector Cleaning

□ 1. Make a solution of 80% isopropyl alcohol (99.5% electronic
W1 grade) and 20% distilled water.
□ 2. Soak a soft lint-free cloth in the solvent mixture.
□ 3. Work the soft lint-free cloth in a back and forth motion par-
allel to the edge connector contacts.
□ 4. If necessary use the nonabrasive eraser to remove tarnish

or stains. A fiberglass or nylon burnishing brush may also be
used.
NOTES:
1. Minimize electrostatic discharge by using the 80% to 20% isopropyl alco-
hol to distilled water solution during burnishing.
2. Do not use excessive force while burnishing. Use only enough force to
shine the contact surface. Inspect the edge connector after cleaning to assure
no loss of contact surface.
□ 5. With a clean soft lint-free cloth in a back and forth motion

parallel to the edge connector contacts.
□ 6. Dry the edge connector contact area by wiping with a clean

soft lint-free cloth.
Connections Check PR15
Purpose/Scope
30 min.
This procedure describes the connections check maintenance
procedure. Check all signal wiring, power, ground, and cable
connections within the enclosure to verify their integrity.
Parts None.
Tools • Flat-blade screwdriver.
• Phillips screwdriver.

WARNING maintenance procedure. Failure to do so could result in severe
or fatal shock, or equipment damage.
Procedure
When checking connections, always turn a screw, nut, or other
fastening device in the direction to tighten only. If the connec-
tion is loose, it will be tightened. If the connection is tight, the
tightening action will verify that it is secure. There should not
be any motion done to loosen the connection.
NOTE: ABB Automation recommends this preventive maintenance task be
performed during power supply preventive maintenance while the power to the
enclosure is off.
□ 1. Verify that power is removed before checking any connec-

W1 tions for tightness.
□ 2. Verify that all power wiring connections are secure.
□ 3. Check all cable connections.

This procedure gives the steps necessary to run offline diag-
nostics. The diagnostics run in the INICT12 module.
Parts None.
Tools None.
Procedure
□ 1. Verify the system is offline or run the diagnostics with the
INICT12 module in a test enclosure.
□ 2. Remove the module being tested from the module mount-

ing unit. Refer to procedure section PR13 if necessary.
□ 3. Enable diagnostic mode by setting switch SW3 as shown in

Table PR16-1. Putting the INICT12 module into diagnostic
mode allows the module to perform a variety of diagnostic tests
but suspends normal operation.

1. Test is not continuous.
Display Mode
Test Number The test number display mode uses LEDs one through six to
display the diagnostic test number and LED eight to display
whether the test passed or failed (Fig. PR16-1). If a diagnostic
test is successful, LEDs one through six display the diagnostic
test number and LED eight does not illuminate. If a diagnostic
test is not successful, LEDs one through six still display the
diagnostic test number but LED eight will illuminate. LED
seven is not used in test number display mode.
Procedure
Pass/Fail Count The pass/fail display mode uses LEDs one through eight to
display a combination of incrementing pass and fail counters
(Fig. PR16-1). LEDs one through four display a binary count of
the number of passed tests and LEDs five through eight dis-
play the number of failed tests.
Halt On Error
Disabled If halt on error is disabled, the selected test runs repeatedly
until the module is removed. Depending on the display mode,
the status indicators will identify the test being run or will dis-
play a test count (Fig. PR16-1).
Enabled If halt on error is enabled, the test stops if an error is encoun-
tered. Depending on the display mode, the status indicators
will identify the test that failed or will display a test count. The
test continues to run, however, if no error is detected.
Diagnostic Tests
Table PR16-4 describes the diagnostic tests.
Table PR16-4. Diagnostic Tests
Test ID Description
00 LEDs and Performs walking one test on the LEDs, then the byte value of SW3 and
switches SW4 are exclusive ORed together. Results are displayed on LEDs. The
status LED is off for even or on for odd total.
01 CPU Verifies CPU and CPU instruction set operation.
02 ROM Calculates checksum of ROM and compares it to an expected value. If the
test fails:
1. Download firmware to the module.
2. Replace the module.

0A Timer IRQ5 Tests IRQ5 interrupt handling. Initializes DUART timer for 1-msec inter-
rupt and then waits for it to time-out.
0B Dispatcher IRQ2 Tests IRQ2 interrupt handling. Issues software dispatcher request and
waits for interrupt to occur.
0C RS-232-C local Tests both serial channels of DUART circuitry in local loop back mode.
Checks internal circuitry only.
10 Group test Executes tests 01 to 0C.
11 I/O expander bus Tests I/O expander bus communication with another module. Requires an
IMDSO14 module set to module address 15. IMDSO14 LEDs count suc-
cessful tests. Verify MMU backplane connection between INICT12 and
IMDSO14 modules before starting test.
12 I/O expander bus Tests IRQ3 interrupt handling. Enables an interrupt level 3 and then writes
IRQ3 a value to the I/O expander bus to initiate an interrupt.
26 NVRAM retention Test NVRAM ability to retain stored data. Test 26 and 27 operate together.
- data storage To run test:
27 NVRAM retention 1. Select test 26. Stores a known data pattern in NVRAM. Displays 0x55
- data check on LEDs if successful.
