COMMUNICATION INTERFACE MODULE (CIM)
VERSION 3.0
1. Introduction
This section is intended version 3.0 of the Communication Interface Module (CIM). For
other product versions, contact Thomson Technology, Inc. to obtain applicable
instruction manuals.
The Thomson Technology (TTI) remote communication system with the CIM 3.0 and
Modbus™ protocol provides remote monitoring and control of TTI microprocessor-based
controllers as used in the power generation industry. The system consists of 2 main
components as follows:
• Communication Interface Module (CIM): The CIM provides the hardware and
software interface between a Modbus compliant device (customer supplied) and the
specific microprocessor-based controllers as used at a generator site.
• Remote Terminal Unit (RTU): An RTU is a device that directly operates the
equipment at a generator site. These devices are the actual microprocessor-based
controllers as developed by Thomson Technology, Inc. (e.g. MEC 20 engine
controller or TSC 800 transfer switch controller.
The following diagram depicts a typical remote communication system.

SECTION 1 COMMUNICATION INTERFACE MODULE
Some advanced features of the remote communication system with the CIM 3.0 module
and Modbus™ protocol are as follows:
• One CIM module can control and monitor up to 10 RTUs at a generator site using a
single direct serial/phone link.
• Configuration of all communication system setpoints is done using software.
• CIM Port #2 can be configured for RS-232, RS-422 or RS-485 serial communication
types. RS-485 communication allows multiple CIM's to be interconnected to any
Modbus™ RS-485 network. RS-485 is recommended for the best distance and noise
immunity. Port #2 has a hardware protocol auto-detection option that removes the
confusion of determining whether the port is in RS-232 or RS-485 mode. Just plug in
and communicate (assuming the baud rate etc. is set correctly).
• Security features have been implemented to allow password protection. However
these features along with auto-detection and modem functionality can be bypassed
with a "fixed Modbus" option that is intended for direct PLC function where remote
access is not necessary.
• With onboard modem support, CIM 3.0 offers remote telephone connectivity with
auto callout and pager support with up to 32 characters. Up to 3 phone numbers can
be programmed into the CIM for remote THS connection or pager notification. In the
case of a failed connection, retries can be specified.
Further information on the Modbus™ protocol support on the CIM can be found in
SECTION 3 and at the Modicon website (www.modicon.com
).
NOTE: Throughout this document, CIM's, MEC 20's and TSC 800's are generically
referred to as remotes.
2. General Description
The Communication Interface Module (CIM) is an advanced communication interface
device for remote communication to Thomson Technology's latest generation of
Microprocessor-based engine generator and transfer switch control products. One CIM
module can communicate with networked MEC 20 engine generator controllers or TSC
800 transfer controllers. The serial communication ports can be used for direct
connection to a personal computer (port #2) or to other remote connected devices (port
#3). An internal modem is available with the CIM, which provides direct connection to a
telephone system.
PM055 Rev 2 00/08/31 Thomson Technology
2
SECTION 1 COMMUNICATION INTERFACE MODULE
The CIM provides the following advanced features:
• Dedicated Microprocessor-based design provides fast operation without restricting
RTU operation.
• One CIM module can provide interface to a complete networked RTU system. This
leads to a single telephone line connection per site rather than typical multiple line
solutions.
• Internal 14.4 kbaud modem available for direct connection to telephone system.
• Flexible design provides two fully configurable serial ports.
• Standard plug-in telephone RJ45/RJ11 type jacks and DB9 computer ports provide
simple interconnection to system.
• The ability to callout to a THS host station or pager when an RTU fault occurs frees
the user from continual monitoring. It also allows for immediate remote response to
problems.
3. Hardware Interface
The main features of the CIM are described as follows with reference to the following
figure.

SECTION 1 COMMUNICATION INTERFACE MODULE
3.1. DC Power Input: Terminals are provided for DC power input to the CIM
module. Power input is non-polarity sensitive and can range from 8-
35Vdc.
3.2. Telephone Port: The telephone port is used to interconnect to a telephone
system. This port is internally connected to a 14.4 Kbaud modem. This
port uses a 6 pin RJ11 plug-in jack connection.
3.3. Diagnostic LEDs: The CIM module provides four diagnostics LED lights
are described as follows:
• Power: This LED is illuminated whenever the CIM has correct DC
supply voltage applied.
• Service: This LED illuminates when the CIM has an internal fault in
which the unit must require service.
• DC Fault: This LED is illuminated whenever the CIM's internal power
supply has shutdown do an internal fault or an external overvoltage
condition from the DC supply input. To reset a DC fault, the DC supply
voltage must be removed for 30 seconds, then re-applied.
3.4. Internal Modem: The CIM is provided with an internal 14.4 Kbaud
modem. The modem is internally connected between the telephone port
and port 2A/B.
3.5. Port 2B: Port 2B may be interconnected to a remote terminal unit (RTU)
or Personal computer (PC). Port 2B can be configured to RS-232 or RS-
485/-422 type transmission signal. When a personal computer is
connected to Port 2B, a null modem cable or connector must be used.
When the CIM modules' internal modem is used, port 2B is disabled. This
port uses an 8 pin RJ45 plug-in connector. An LED indicator is provided
to signal when the port is communicating. Port 2B is internally wired in
parallel with Port 2A.
3.6. Port 2A: Port 2A may be interconnected to a remote terminal unit (RTU)
or PC. Port 2A can be configured to RS-232 or RS-485/-422 type
transmission signal. When a personal computer is connected to Port 2A,
a null modem cable or connector must be used in series with the PC
cable. When the CIM modules' internal modem is used, port 2A is
disabled. This port uses a 9 pin standard DB9 female plug-in connector.
PM055 Rev 2 00/08/31 Thomson Technology

SECTION 1 COMMUNICATION INTERFACE MODULE
An LED indicator is provided to signal when the port is Transmitting. Port
2A is internally wired in parallel with Port 2B.
3.7. Port 3B: This port may be interconnected to a remote terminal unit (RTU).
Port 3B utilizes a RS-422 type transmission signal that is compatible with
MEC 20 or TSC 800 controllers. The standard connection for a MEC 20
or TSC 800 controller (RTU) application is for port 3B to be connected to
the RTU. This port uses an 8 pin RJ45 plug-in connector and allows for a
direct connection to TTI MEC 20 and/or TSC 800 controllers. Port 3B is
internally wired in parallel with Port 3A.
3.8. Port 3A. This port may be interconnected to a remote terminal unit (RTU)
or directly to a PC. Port 3A utilizes a RS-422 type transmission signal that
is compatible with MEC 20 or TSC 800 controllers. The standard
connection for a MEC 20 or TSC 800 controller (RTU) application is for
port 3A to be connected to the RTU. This port uses a 9 pin DB9 female
connector. Port 3A is internally wired in parallel with Port 3B.
NOTE: CIM Port 2 cannot be used concurrently with the modem (CIM Port 1). An RS-
232 or RS-422 cable can be connected to the CIM, but cannot be active if the modem is
to be used. An RS-485 connection will effectively disable the modem whether it is active
or inactive.

7. CIM Operation Functions
The CIM module provides the following main functions when used in a communication
system:
RTU & Modbus™ Device Interface: The CIM is the main communication interface
component between a Modbus™ compliant device and the remote terminal units. The
CIM provides the necessary hardware interface (i.e. COM Ports) as well as the
Modbus™ software protocol interface.
Protocol Data Processing: The CIM receives incoming communication signals from
various types of RTUs and processes the data into the specific Modbus™ language as
required for the application. The processed data then gets transferred to the applicable
port and transmitted to a remote Modbus™ compliant device.
CIM Configuration: The CIM stores vital information in non-volatile FLASH memory
pertaining to a specific RTU site as defined by the user. Stored information includes, site
name, site passwords, and auto callout phone numbers (3).
RTU Polling: The CIM module will automatically poll connected RTUs to determine their
operating status and to signal an auto callout (callout is only operational when the
modem feature is operational) to the remote Modbus™ compliant device to alert a user
of an abnormal condition.

10. CIM Installation
NOTE: Installations should be done according to all applicable electrical regulation
codes as required.
The following installation guidelines are provided for general information only pertaining
to typical site installations. For specific site installation information, consult Thomson
Technology as required.
CAUTION!!! Qualified personnel must do all installation and/or service work
performed only. Failure to do so may cause personal injury or death.
10.1. Battery Supply Input
The CIM can operate on any battery supply from 8 to 35 volts DC nominal
Wiring from the system battery to the CIM should conform to the following
guidelines to avoid possible communication module malfunction and/or
damage.
Avoid wiring from the engine starter terminals - wiring should go directly
from the battery terminals to the control panel where the CIM module is
located (to avoid voltage drop in the starter cables and starter motor
commutation noise).
CAUTION!!! The battery charger must be turned off before battery cables
are removed from the battery (i.e. for servicing). Failure to do so may
subject the control panel to an overvoltage condition in which damage
may result.
Under noisy environments (i.e. gas engines with high voltage ignitions,
etc.), wiring from battery should be a twisted pair of #14 AWG (2.5mm2)
wires.
The use of AC or DC operated solenoids or relays in control systems can
sometimes cause high voltage spikes on the DC power supply, which
may cause electronic devices to fail. Transient suppression devices are
recommended for all inductive devices sharing wiring or if physically
located near the CIM module. For DC operated relays or solenoids, use a
suitably rated counter EMF Diode (or commonly known as "freewheeling"
diode). For AC operated relays or solenoids, use a suitably rated metal
oxide varistor (MOV) or capacitor/resistor suppressor.
PM055 Rev 2 00/08/31 Thomson Technology

SECTION 1 COMMUNICATION INTERFACE MODULE
10.2. Remote Communication Wiring
All communication interconnecting wiring to/from the CIM Module shall
utilize #22 AWG-8 wire, twisted, shielded cable with RJ45 connectors.
All remote communication wiring outside the control panel must be run in
separate conduit and shall not be located near AC power cables to
prevent pick-up of induced voltages.
10.3. Dielectric Testing
Do not perform any high voltage dielectric testing on the CIM connected
in the circuit as serious damage will occur to the module.
10.4. Mounting Location/Installation
The CIM Module is designed for mounting directly onto a control panel
inner sub-panel. Considerations should be given for the following:
The controller should be installed in a dirt free, dry location away from
extreme heat sources. Adequate space should be provided around the
CIM module for control wiring.

10.6.2. RS-485/-422 Connection
The following hardware configuration is required for 4 wire RS-
485/-422 from the port 2 on the CIM to an RS-232 port on a
computer:
The following parts are connected in order from the RS-232 side
(computer) to the RS-485/-422 side (the CIM).
RS-232 to RS-485 or RS-422 adapter (set to DCE)
DB-25 to RJ45 adapter (or custom cable) for RS-422/-485 on the
CIM port 2(see below wiring).
Insure that the correct handshaking signals are connected on the
RS-232 side of the RS-485/-422 converter. Many RS-485
converters use the RTS line to control the transmitter (which must
be tri-stated during receive mode). It is important to insure that the
converter is configured correctly and the correct handshaking lines
are wiring appropriately. If the handshaking lines (RTS) are not
wired correctly the connection may appear to work but damage
may occur and communications may be unreliable over time.

11. Troubleshooting
Refer to the following list of typical problems. Consult the factory for any detailed
information or for any problems not listed.
CAUTION!!! Before opening the enclosure to perform any service task, it is
imperative to isolate the control system from any possible source of power.
Failure to do so may result in serious personal injury or death due to electrical
shock.
Service procedures must be undertaken by qualified personnel only!

Verify all settings in the THS 2000 program are correct. Critical
settings are as follows:
Port 3 baud rate--4800
Controller address--THS setting and controller setting must
match
Site Name--THS setting and CIM setting must match. Note:
factory default setting in CIM is "site"
Site Password--THS setting and CIM setting must match. Note:
factory defeat setting in CIM is "user".

Verify PC modem is set for 9600 baud operation.
Ensure phone numbers programmed for both PC site location
and RTU equipment location are correct.
If you encounter difficulty connecting to a CIM with the Host
software make sure the CIM is not trying to call-out. When the
CIM is trying to call-out to the Host sites it will not respond to
outside requests for connection. In this situation the user can be
patient and make repeated attempts at connection until the CIM
has exhausted its phone numbers and retries (can be over 12
mins in some cases with 3 numbers and 3 retries). Or the user
can let the host successfully call-out to the Host software. After
the phone numbers are successfully attempted or retries are
exhausted the CIM will go back into a log-in ready state. If time is
important, the CIM may be power cycled, for a brief time after the
CIM power is restored (after the 2 quick blinks on the Port 2
LED) the CIM will be log-in ready. However the CIM will
eventually go into a call-out state to report the site alarm
situation.

For Modbus communications ensure that the CIM is being
addressed with the correct node address. The factory default
CIM node address is '1', this should not be confused with the
RTU node addresses connected to Port 3 of the CIM.
11.1. Database Re-initialization
If state of the internal database is unknown a reset to factory default
conditions can be done by the following procedure:
a) Remove power from the CIM.
b) Remove the CIM back cover.
c) Connect a wire from the CIM ground terminal located next to the power
connections.
d) Connect the other end of the ground wire to the testpoint located on
the bottom of the daughter board (the daughter board is plugged into the
bottom of the CIM motherboard) located on the bottom of the CIM that
should be visible with the bottom cover removed.
e) With the bottom testpoint grounded carefully apply power to the CIM
for at least 2 seconds. You may now remove power and reassemble the
CIM. The CIM has defaulted back to factory settings.

THS 2000 SOFTWARE PROGRAM
1. Introduction
The THS 2000 software program remotely controls and monitors a Thomson Technology

Microsoft Windows 98™, Microsoft Windows NT™ 4.0 or Microsoft Windows 2000 operating
systems (www.microsoft.com
communicate to TTI generator control system site. A site consists of a single Communication
Interface Module (CIM) and one or more associated Remote Terminal Unit (RTU) controllers.
The THS 2000 software is designed to allow a direct connection (via RS-232, RS-422 or RS-
485) to Port 2 of the CIM or a remote connection (via a host PC modem) with the internal
modem of the CIM on Port 1. The host PC modem must already be configured before
attempting a remote connection. See the operating-system help for installing and configuring
modems.
Version 3.1 of the THS2000 is intended for operation with version 3.0 of the CIM, but also
provides support for previous versions of the CIM.

1.2. Improvements
A number of improvements have been made to this version of the THS 2000 software.
Most of the improvements correspond to added features of CIM version 3.0, but some of
the changes are applicable to the previous version of the CIM. See See Section 1
more information on device-specific features and Section 3
for the Modbus protocol.
for
The most notable improvement is the use of the Modbus protocol for communications to
the CIM.
The new features in THS 2000 are:
• Support for new CIM 3.0 Modbus protocol as well as previous CIM protocol versions.
• Automatic RTU (MEC 20 and TSC 800) discovery on login. This will eliminate the
need for the user to program the individual node address and controller type for each
site (CIM). See Controller Discovery
.
• Support for these additional CIM 3.0 features:
32 character telephone numbers for callout, see Auto-answer Configuration
call all numbers option for CIM callout, see Auto-answer Configuration
CIM Port 2 auto-detect feature for the hardware protocol, see CIM Port 2
bounded controller addresses for faster detection, see CIM Advanced
;
;
;
.
• CIM Port 2 can now be configured for speeds from 1200bps up to 19.2kbps, instead
of being fixed at 9600bps. This works for old CIM versions as well.
• Support for multiple remote callout sites. THS version 1.0 and 1.1 only support auto-
answer for a single site. A system with two CIM sites that can callout, would not work
correctly. This has been fixed by adding multiple sites to a single THS 2000 file. The
calling-in CIM is then identified from the loaded set of sites. See Site-list
Management.
• The MEC 20 digital fault labels that are disabled are blanked out in THS 2000. This
feature requires the latest version of the MEC 20.
• Improved communications reliability over noisy communication lines.
THS2000 version 3.1 adds the ability to connect directly to an RTU, bypassing the
CIM. A maximum of one RTU, MEC20 or TSC800, is allowed. The auto-answer
feature of THS2000 is not supported in this mode, as it is a function of the CIM. The
auto-discovery of controllers is likewise not available. See CIM Bypass Wiring
for a
wiring description.
1.3. Computer System Requirements
The supported operating-systems are:
PM055 Rev 2 00/08/31 Thomson Technology
17
SECTION 2 THS 2000 SOFTWARE PROGRAM
• Microsoft Windows 95™, Service Release 2 or later;
• Microsoft Windows 98™;
• Microsoft Windows NT™ 4.0 Workstation or Server, Service Pack 3 or later;
• Microsoft Windows 2000.
A minimum of 2 MBytes of hard drive space on the chosen installation drive is necessary
for proper operation.
A modem that is fully supported by the operating-system is required for remote
operation. It is important that the correct modem driver software is installed correctly.
A FIFO-enabled serial-port is required for direct connections.
Microsoft Internet Explorer™ 4.01 or later is recommended for use with the on-line help.
However, Microsoft Internet Explorer 3.02 is sufficient if the hhupd.exe file, included with
the THS 2000 distribution, is run first; this executable is provided by Microsoft for
updating help file support.
1.4. Installation
The THS 2000 software consists of two files, the THS3v0.EXE file and the
THS3v0.CHM file. Both files should be copied to a directory on your hard drive, such
as C:\THS. The first file, THS3v0.EXE is the THS 2000 executable. You can make a
link to this file on your desktop by dragging and dropping the THS3v0.EXE from the
explorer to the desktop. The second file, THS3v0.CHM, is the on-line help file.
If you are using Microsoft Internet Explorer 3.02, the file hhupd.exe will be required to
execute and update a system file for HTML Help support. That file is not required if
Microsoft Internet Explorer 4.01 or later is installed.
2. Quick Start
This section will get you up and running the THS 2000 quickly and easily. This chapter covers
the simple tasks that are necessary to communicate with a site. More advanced topics will be
covered in a later section.

and Starting And Logging On.
2.3. Step 3: Set Host Connection Method
Select the Connect command from the Site menu (or toolbar button or press F9 ). This
command will normally bring up a list of accessible sites, however, if no sites are
defined, you will be required to choose a host connection method. This dialog box is
shown below.
Select your connection method, either a specific modem (e.g. Hayes Accura 288 V.34 +
FAX) or a serial port (e.g. Direct using COM1). If you select a direct communications
port, you are also able to modify the port settings. The default settings are likely
sufficient for now, so click the OK button.
