Description

The GE Fanuc IC693CMM311 is a Communication Coprocessor Module (CMM) designed for the Series 90-30 Programmable Logic Controller (PLC) system. This module provides enhanced communication capabilities, allowing the PLC to interface with external devices such as operator interfaces, computers, and other controllers. It offloads communication tasks from the main CPU, ensuring efficient processing and data exchange within the industrial control network.

Features

  • Supports multiple communication protocols including CCM, RTU, and SNP.
  • Equipped with two communication ports using 25-pin D-shell female connectors.
  • Port 1 supports RS-232 applications; Port 2 supports both RS-232 and RS-485 applications.
  • Integrated status LED indicators for Module OK, Port 1, and Port 2 activity.
  • Designed for installation exclusively on the Series 90-30 CPU baseplate.
  • Allows up to four CMM modules per baseplate depending on system configuration.

Applications

This module is widely used in industrial automation environments requiring serial data communication, such as factory floor data acquisition, integration with HMI panels, and serial link connectivity between GE Fanuc PLC systems and third-party equipment.

Installation Guidelines

  • Ensure the PLC system power is disconnected before installing or removing the module from the baseplate.
  • The IC693CMM311 must be installed into a slot on the CPU baseplate. Ensure the module is fully seated to maintain proper backplane contact.
  • Use shielded communication cables to minimize electromagnetic interference (EMI) in industrial environments.
  • Observe proper ESD (Electrostatic Discharge) handling procedures when touching the module circuitry.
  • Verify that the total current draw of all modules on the baseplate does not exceed the power supply capacity.

FAQ

What protocols does the IC693CMM311 support?

The module supports CCM (Computer Communication Method), RTU (Remote Terminal Unit), and SNP (Series 90 Protocol) for serial communication.

Can I install this module in any slot on the Series 90-30 rack?

No, the IC693CMM311 is specifically designed to be mounted on the CPU baseplate of the Series 90-30 system.

Does Port 1 support RS-485?

No, RS-485 communication is supported only on Port 2 of this module. Port 1 is limited to RS-232 applications.
