General Electric IC693CMM311E Series 90-30 Communication Coprocessor Module

The General Electric IC693CMM311E is a communication coprocessor module engineered for the GE Fanuc Series 90-30 programmable logic controller platform. This module operates as an intelligent interface that offloads serial communication processing from the main CPU, providing two independent serial ports for versatile device integration in industrial automation systems.

Dual Serial Port Architecture

The hardware features two configurable serial ports designed to manage complex data exchanges with external peripherals such as operator interfaces, variable frequency drives, and barcode scanners. By handling protocol execution locally, the module minimizes processing overhead on the host CPU and supports reliable serial data integration.

Diagnostics and Power Requirements

Integrated LED indicators provide real-time status monitoring for Module OK, Port 1 activity, and Port 2 activity, enabling rapid diagnostic checks on the plant floor. The unit requires a backplane current draw of 400 mA at 5 VDC and occupies a single slot on the Series 90-30 baseplate.

Installation Guidelines

• Ensure all system power is disconnected from the PLC rack before inserting or removing the module.
• Mount the unit in any available baseplate slot, noting that the dedicated CPU slot is restricted.
• Observe standard electrostatic discharge precautions and handle the hardware by its edges during setup.

Frequently Asked Questions

Q: Can the IC693CMM311E be installed in the CPU slot of the Series 90-30 rack? A: No, the module can be placed in any standard slot on the baseplate except for the designated CPU slot.

Q: How does the module reduce processing demands on the main CPU? A: It acts as an intelligent coprocessor that independently manages serial communication tasks and protocol data exchanges.
