Except for the serial port connectors, the user interfaces for the CMM311 and CMM711 are the same. The Series 90-70 CMM711 has two serial port connectors. The Series 90-30 CMM311 has a single serial port connector supporting two ports. Each of the user interfaces are dis- cussed below in detail.
The three LED indicators, as shown in the figures above, are located along the top front edge of the CMM board.
Module OK LED
The MODULE OK LED indicates the current status of the CMM board. It has three states:
Off: When the LED is off, the CMM is not functioning. This is the result of a hardware mal- function (that is, the diagnostic checks detect a failure, the CMM fails, or the PLC is not pres- ent). Corrective action is required in order to get the CMM functioning again.
On: When the LED is steady on, the CMM is functioning properly. Normally, this LED should always be on, indicating that the diagnostic tests were successfully completed and the configuration data for the module is good.
Flashing: The LED flashes during power-up diagnostics.
Serial Port LEDs
The remaining two LED indicators, PORT1 and PORT2 (US1 and US2 for the Series 90-30 CMM311) blink to indicate activity on the two serial ports. PORT1 (US1) blinks when port 1 either sends or receives data; PORT2 (US2) blinks when port 2 either sends or receives data.
Serial Ports
If the Restart/Reset pushbutton is pressed when the MODULE OK LED is on, the CMM will be re-initialized from the Soft Switch Data settings.
If the MODULE OK LED is off (hardware malfunction), the Restart/Reset pushbutton is inop- erative; power must be cycled to the entire PLC for CMM operation to resume.
The serial ports on the CMM are used to communicate with external devices. The Series 90-70 CMM (CMM711) has two serial ports, with a connector for each port. The Series 90-30 CMM (CMM311) has two serial ports, but only one connector. The serial ports and connectors for each PLC are discussed below.
Serial Ports for the IC693CMM311
The Series 90-30 CMM has a single serial connector which supports two ports. Port 1 applica- tions must use the RS-232 interface. Port 2 applications can select either the RS-232 or
RS-485 interface.
NOTE
When using the RS-485 mode, the CMM can be connected to RS-422 devices as well as RS-485 devices.
The RS-485 signals for port 2 and the RS-232 signals for port 1 are assigned to the standard connector pins. The RS-232 signals for port 2 are assigned to normally unused connector pins.
IC693CBL305 Wye Cable
A Wye cable (IC693CBL305) is supplied with each Series 90-30 CMM and PCM module. The purpose of the Wye cable is to separate the two ports from a single physical connector (that is, the cable separates out the signals). In addition, the Wye cable makes cables used with the Se- ries 90-70 CMM fully compatible with the Series 90-30 CMM and PCM modules.
The IC693CBL305 Wye cable is 1 foot in length and has a right angle connector on the end that connects to the serial port on the CMM module. The other end of the cable has dual connec- tors; one connector is labeled PORT 1, the other connector is labeled PORT 2 (see figure be- low).
The IC693CBL305 Wye cable routes the Port 2, RS-232 signals to the RS-232 designated pins. If you do not use the Wye cable, you will need to make a special cable to connect RS-232 de- vices to Port 2.

Programmer Connection Through The Communications Coprocessor Module IC693CMM311
Description
Programmer Connection Through The Communications Coprocessor Module IC693CMM311
Resolution
Change the CMM config to SNP (RS-232 is needed), and run the programming software through the CMM using either the IC690CBL702 (9-pin AT). The best way to connect would be through Port 1 of the CBL305 (wye cable for the CMM). Due to firmware limitations this will give you Level 2 access only? Write to any data memory, except overriding discrete I/O. The PLC can be started or stopped. PLC and I/O fault tables can be cleared. Cbl702 pinout is:
9 pin 25pin1->4-------82-----------23-----------37-----------58-----------205-----------7------------1 shield
Programming Functions Through CMM Serial Ports
Description
Programming functions are not available on Communications Co-processor ports (IC693CMM311, and IC697CMM711) as per GFK-0307F.
Resolution
As an SNP slave, CMM module provides additional communications port(s) for connection to remote operator interface units or other SNP communications devices. The MS-DOS or Windows based software package may be connected to an SNP slave port on a CMM module for data monitoring only. Programming and configuration of IC69* PLCs are not possible through the CMM SNP ports.
Customer Questions and Answers
- Question: What is an IC693CMM311? Answer: The IC693CMM311 is a Communications Co-Processor module. It is a high-performance microcomputer designed to perform communications functions in a Series 90 PLC system. It includes a high-performance, co-processor for the 90-30 modular CPU's. The device supports the following protocols: GE Fanuc CCM communications, RTU (Modbus) communications, and SNP.
- Question: How many IC693CMM311 will fit into a main rack? Answer: Each IC693CMM311 occupies a single slot in a Series 90 PLC rack. So, in Series 90-30 PLCs, up to 4 IC693CMM311s may be installed in the main rack (the baseplate).
- Question: Where should the IC693CM311 reside in the baseplate? Answer: For Series 90-30 PLCs, the CMM's must reside in the CPU rack (baseplate). There is a slot for the power supply and slot 1 is reserved for the CPU module. The CMM can reside in any other slot. There are NO Bus Expansion Modules as there are for the Series 90-70 PLCs.
- Question: What 3 states does the module's OK LED have? Answer: The first state is off, meaning that the IC693CMM311 is not functioning. This is the result of a hardware malfunction and corrective action is required to get the module working again. The second state is on, meaning the IC693CMM311 is functioning properly. Normally, this LED should always be on, indicating that the diagnostic tests were successfully completed and the configuration data for the module is good. The third and final state is flashing; the LED flashes during power-up diagnostics.
- Question: What will I need when I am in the process of installation and configuration of the IC693CMM311? Answer: For a complete list of what you will need, please refer to our datasheet user-manual (page 2-7).
- Question: How do I know IC693CMM311, upon testing, is working correctly? Answer: You will get an immediate response that says "reply from" followed by the address you have selected.
- Question: Troubleshooting continued. Answer: If you plug the IC693CMM311 module of the GE 90-30 Series in and you do not get a green OK LED light, then your device could be faulty.
- Question: If IC693CMM311 is not responding or the OK light is not on, what is my next step? Answer: If IC693CMM311 is not responding or the OK light is not on, your IC693CMM311 might need repair.
For more information on the IC693CMM311 Module of the GE 90-30 Series, please see the Datasheet Manual.
