Description

The IC693CMM321 is a Communications Coprocessor Module (CCM) designed for the General Electric Series 90-30 Programmable Logic Controller (PLC) platform. This module enables the PLC to interface directly with Ethernet TCP/IP networks, facilitating communication with host computers, other PLCs, Human Machine Interfaces (HMI), SCADA systems, and Distributed Control Systems (DCS). It serves as a critical bridge for implementing distributed I/O and remote station management.

Features

  • Supports up to 16 concurrent server connections for robust network communication.
  • Includes one RS-232 RJ-11 Station Manager port.
  • Includes one RS-485 15-pin D-type Software Loader port.
  • Equipped with an AAUI port for network connectivity (requires external transceiver).
  • Integrated LED status indicators for OK, LAN, SER, and STAT monitoring.

Applications

  • Automotive: Assembly robotics and paint shop control systems.
  • Energy and Power: Power plant, substation, and grid management.
  • Oil and Gas: Refinery ESD, safety systems, and pipeline monitoring.
  • Pharmaceutical and Chemical: Batch processing and recipe management.
  • Transportation: Signaling systems and baggage handling infrastructure.

Installation Guidelines

  • The module can be installed in any slot of a Series 90-30 baseplate, with the exception of Slot 1, which is reserved for the CPU.
  • A maximum of two IC693CMM321 modules may be installed per system.
  • Ensure the PLC rack is powered down before inserting or removing the module to prevent electrical damage.
  • Use appropriate shielded cabling for serial and Ethernet connections to minimize EMI interference.
  • Configure the module using Logicmaster 90-30 (v6.01+), Control (v2.01+), or VersaPro (v1.0+) software to assign the IP address and subnet mask.

FAQ

What is the IC693CMM321?

It is a communications coprocessor module that provides full communication access to Ethernet LAN networks for the GE Series 90-30 PLC system.

How many modules can be used in a single rack?

Up to two IC693CMM321 modules can be installed in a single Series 90-30 baseplate.

Does the module support redundant media?

No, the IC693CMM321 does not support redundant Ethernet topology.

What if the LAN light is not blinking?

This indicates no physical network connection. Check the 10BaseT port connection or the external transceiver connected to the AAUI port.
