GENERAL
WARNINGS Equipment Environment
All components, whether in transportation, operation or storage,
must be in a noncorrosive environment.
Electrical Shock Hazard During Maintenance
Disconnect power or take precautions to insure that contact with
energized parts is avoided when servicing.
Special Handling
This module uses electrostatic sensitive devices.
SPECIFIC
WARNINGS Never clean electrical parts or components with the power on.
Doing so exposes you to a fatal electrical shock hazard. (p. 6-2)
Wear eye protection whenever working with cleaning solvents.
When removing solvents from printed circuit boards using com-
pressed air, injury to the eyes could result from splashing solvent as
it is blown off the printed circuit board. (p. 6-2)
SPECIFIC
CAUTIONS When the IMCPM03 module is being used as a LAN-90 PCV inter-
face, insure a restart command is not issued from an engineering
work station. This command will delete the LAN-90 PCV established
database. (p. 2-2)
To avoid potential module damage, evaluate your system for com-
patibility prior to module installation. This module uses connections
to the module mounting unit backplane that served other functions
in early Network 90 systems. (p. 3-2)
Only qualified personnel should configure these dipswitches. Dam-
age or misoperation could occur if dipswitches are improperly con-
figured. (p. 3-7)
It is strongly recommended that all power (cabinet, I/O, etc.) be
turned off before doing any wiring. Verify all connections before
applying power. Failure to observe these precautions could result in
equipment damage. Do no apply power to the termination unit when
uncut dipshunts are installed. This may result in damage to the ter-
mination unit. (p. 3-13)

OVERVIEW
The IMCPM03 Communication Port Module connects the
CTT02 Configuration and Tuning Terminal and an engineering
work station (EWS) or a LAN-90Process Control View PCV
work station to a single INFI 90 Open process control unit
(PCU). The IMCPM03 module provides all the functions of the
IMSPM01, IMCPM01 and IMCPM02 modules. It can be
installed in PCUs that use either Controlway or module bus.
The IMCPM03 also provides the database capability of the
Elsag Bailey family of network interface units.
This instruction explains the purpose, operation and mainte-
nance of the IMCPM03 module. It explains handling cautions
and steps for installation. Refer to Figure 1-1 for the INFI 90
Open communication levels and where the IMCPM03 module
resides within these levels.
Applications that require local tuning and configuration of
modules in an INFI 90 Open PCU unit can use the IMCPM03
module. The IMCPM03 module interfaces to a CTT terminal, an
EWS work station or a LAN-90 PCV operator console. The
IMCPM03 module minimizes hardware requirements.

INTENDED USER
The installation engineer needs to know how to handle and
work with electronic equipment safely. Installers should have
formal training in INFI 90 Open processes and configuration.
DESCRIPTION
The IMCPM03 module is a microprocessor-based INFI 90 Open
interface module that provides a local (within the PCU) means
of system data monitoring, configuration, tuning and diagnos-
tics; it handles all communications with a LAN-90 PCV opera-
tor station. The module was specifically designed for exclusive
use in interfacing Elsag Bailey’s consoles, software tools and
software application products with the INFI 90 Open system.
Elsag Bailey offers a full range of other products for integrating
non-Elsag Bailey applications with the INFI 90 Open system.
The IMCPM03 interfaces the CTT terminal and EWS station to
the Controlway or module bus through faceplate connectors.
The IMCPM03 module enables the user to configure, tune and
monitor the controller modules and their function blocks. It
can communicate with controller modules in a single PCU that
uses either module bus or Controlway. The IMCPM03 can also
be used for data acquisition and control between controller
modules and PC-based Elsag Bailey software (i.e., LAN-90 PCV
work station).
The IMCPM03 module has one two-color (red/green) LED and
eight red LEDs for module status indication. There are two
eight-pole dipswitches that set the Controlway or module bus
address, select baud rate and enable diagnostic testing. A reset
switch is available through the faceplate.
The IMCPM03 has three connectors. A DB-25 connector for the
RS-232-C cable from the EWS station or the LAN-90 PCV and a
round five-pin connector for the CTT terminal are on the face-
plate. A DB-9 connector for the EWS is located on the compo-
nent side of the module close to the faceplate. Both the DB-25
and the DB-9 connectors are optically isolated.
The IMCPM03 module occupies a single slot in a standard INFI
90 Open module mounting unit (MMU). An optional termina-
tion unit can be connected through a cable for permanent
mounting.
Faceplate
The faceplate measures 35.5 millimeters (1.4 inches) wide by
177.8 millimeters (7 inches) high. Two concentric screws lock
the module assembly into the module mounting unit. A win-
dow on the faceplate shows the CPU LEDs during operation.
The faceplate also protects the circuit components and creates
a chimney for proper air flow within the cabinet.

INTRODUCTION
I-E96-225A 1 - 3
Circuit Board
The circuit board has static random access memory (SRAM),
read-only memory (ROM), a processor running at 16 megahertz
and direct memory access (DMA) circuits. The circuit board
also has custom bus circuits and support circuitry. The board
attaches to the faceplate with two screws.

SECTION 2 - DESCRIPTION AND OPERATION
INTRODUCTION
The IMCPM03 module hardware contains several functional
blocks working together. To understand how they work, this
section shows them in a block diagram and then explains each
block in the text. Refer to Figure 2-1.
THEORY OF OPERATION
When functioning as a CTT interface, the IMCPM03 module
accepts a module bus message from the CTT terminal and
sends the message to the destination module through the Con-
trolway or module bus. The module reply is then received by
the IMCPM03 module and returned to the CTT interface. The
CTT interface and DB-9 EWS port can be used at the same
time as the DB-25 computer port.
When functioning as an EWS interface, the IMCPM03 mod-
ule receives commands, forwards them to the destination

module, and sends the reply to the EWS station over the
RS-232-C channel. The CTT interface and EWS interface
may both be used at the same time. Communications
between the EWS station and IMCPM03 module can take
place through either the DB-25 or DB-9 connector.
When functioning as the LAN-90 PCV console interface, the
IMCPM03 module receives commands from the LAN-90 PCV
interface. The commands are forwarded to the correct destina-
tion module or are acted on by the IMCPM03 module. Replies
are returned to the LAN-90 PCV console software. Communica-
tions between the LAN-90 PCV console and IMCPM03 module
can only take place through the DB-25 connector.
DB-25 COMPUTER PORT
The DB-25 computer port on the IMCPM03 module is capable
of supporting standard baud rates up to 19.2 kilobaud. It is a
full duplex serial data EIA standard RS-232-C type Z (an Elsag
Bailey defined binary interchange). The DB-25 connector on
the IMCPM03 faceplate is optically isolated. Optical isolation
eliminates ground currents caused by isolated grounding of
external equipment.
The serial channel is normally used to interface the Elsag
Bailey hardware when the IMCPM03 module is in the data
communication equipment (DCE) mode (determined by jumper
configuration). It also may be connected to a modem when the
IMCPM03 module is in data terminal equipment (DTE) mode
(determined by jumper configuration). Dipswitch SW2 selects
the desired baud rate and data framing options. Refer to
JUMPER SETTINGS and DIPSWITCH SETTINGS in Section 3.
For more permanent installations, the IMCPM03 module can
be connected to the NIMP01 termination module or NTMP01
termination unit through the NKTU02 and NKTU01 cables,
respectively. Refer to Appendix B and Appendix C.
CAUTION
When the IMCPM03 module is being used as a LAN-90 PCV
interface, insure a restart command is not issued from an engi-
neering work station. This command will delete the LAN-90
PCV established database.
ATTENTION S’assurer qu’une commande de redémarrage n’est pas émise à partir d’un pose de configuration (EWS). Cette commande
effacerait la base de données établie de LAN-90 PCV.

CTT PORT
The IMCPM03 module communicates with the CTT terminal
via the round five-pin connector on the faceplate. Messages
received from the CTT terminal are transmitted on Controlway
or module bus, but using the source module address of the
IMCPM03 module in place of the module address of the CTT
terminal. Only replies to messages initiated by the CTT termi-
nal are transmitted to the CTT terminal. A CTT terminal con-
nected to the Controlway through an IMCPM03 module is a
message-initiating device only. The IMCPM03 module cannot
relay messages to the CTT terminal that are initiated from
other modules within the process control unit.
DB-9 EWS PORT
An optically isolated DB-9 connector is located inside the face-
plate on the circuit board (P6) for use as an EWS port.
MICROPROCESSOR
A 16-megahertz microprocessor is responsible for module oper-
ation and control. The operating system instructions reside in
the read-only memory (ROM). The processor constantly retrig-
gers the machine fault timer (MFT) circuit. If the processor or
software fails and the MFT circuit is not reset, the MFT issues a
board-wide reset and the status LED turns red. In this state,
the IMCPM03 module will not function until it is reset.
CLOCK AND TIMER
The clock section provides the clock signals to drive the module
at 16 megahertz. Additionally, it supplies the clock signals for
the on-board serial port. The timer section is the system clock
that keeps the processor task scheduling at the proper
intervals.
MEMORY
There are 256 kilobytes of ROM and 512 kilobytes of RAM. The
ROM holds the operating system instructions for the proces-
sor. The RAM provides temporary storage.
A key feature of the module memory is that it requires no wait
states. The processor does not need to wait any clock cycles
(zero wait states) before it can check the data in memory. This
results in quicker operation.

MODULE BUS AND CONTROLWAY
Controlway is a one megabaud peer-to-peer communication
link capable of supporting up to 32 drops. The Controlway
interface is provided by a custom Elsag Bailey integrated cir-
cuit that links the IMCPM03 module to Controlway. It has full
direct memory access (DMA) capabilities which permit quicker
operation, and two redundant independent channels. Module
bus is a nonredundant version of the peer-to-peer communica-
tion channel that operates at 83.33 kilobaud.
There are two separate traces on the MMU backplane circuit
for Controlway. Data is transmitted over both channels simul-
taneously and received in separate receivers where it is
checked for integrity. A failed channel on the Controlway is
flagged and shut down to allow Controlway communication to
continue on the other channel.
As the point data between modules travels on the bus, the
Controlway does a bit-by-bit comparison that provides collision
avoidance, maximizing efficiency and throughput.
LEDs
The IMCPM03 module has a single two-color status LED on the
faceplate to indicate the execute or failed status of the
IMCPM03 module. It has eight red status LEDs on the face-
plate for diagnostic purposes and an activity indicator. The
LEDs are arranged vertically and numbered from one through
eight, top to bottom.
In normal operation mode, the IMCPM03 module uses the nine
LEDs on the faceplate to indicate its status. The two-color sta-
tus LED indicates the mode of the IMCPM03 module; green for
execute mode and red for failed mode. When in execute mode,
the IMCPM03 module uses LEDs 1 through 8 as activity indi-
cators.
When the IMCPM03 module is in failed mode, LEDs 1
through 8 display a code indicating the error condition. Refer
to LED ERROR CODES in Section 5. In diagnostic mode, the
LEDs indicate the status of the diagnostic test. Refer to DIAG-
NOSTIC TESTS in Section 5.
DIPSWITCHES AND JUMPERS
The IMCPM03 module has two configurable dipswitches and
eight jumpers.
