Description

The General Electric IC693CMM302 is an Enhanced Genius Communications Module, commonly referred to as the GCM+. This intelligent module is designed for the Series 90-30 PLC platform, facilitating automatic global data communications between the PLC and up to 31 other devices on a Genius bus. The module acts as a bridge for peer-to-peer communication and master-slave operations, enabling the PLC to exchange data with other controllers and monitor Genius I/O blocks.

Features

• Supports global data exchange with up to 31 devices on a Genius bus.
• Enables peer-to-peer and master-slave communication modes.
• Allows for data monitoring of Genius I/O blocks (read-only).
• Supports memory registers: %G, %I, %Q, %AI, %AQ, and %R.
• Equipped with Module OK and COMM status LED indicators.
• Compatible with CPU, expansion, and remote baseplates.

Applications

• Metallurgy and Steel: Monitoring of blast furnace systems and boiler control.
• Chemical and Oil Refining: Production environments requiring high interference resistance.
• Water Treatment: Distributed monitoring for water and sewage treatment plants.
• Power Monitoring: System monitoring for hydropower plants and electrical substations.

Technical Specifications

Installation Guidelines

• Baseplate Placement: The module can be installed in any standard CPU, expansion, or remote baseplate. For optimal performance and reduced sweep impact time, installation in the CPU baseplate is recommended.
• Module Limits: A maximum of 2 GCM+ modules are permitted per PLC system.
• Safety Interlocks: The system prevents the concurrent installation of a standard GCM and an Enhanced GCM+ in the same PLC to avoid configuration conflicts.
• Handling: Ensure the PLC power is disconnected before inserting or removing the module to prevent electrical damage. Use standard ESD protection practices when handling the module.

FAQs

What is the IC693CMM302?

The IC693CMM302 is an Enhanced Genius Communications Module (GCM+) for the Series 90-30 PLC, enabling high-speed data exchange with other devices on a Genius bus.

What is the capacity of the IC693CMM302?

It supports up to 31 devices on the bus, allowing for extensive communication with other PLC systems and I/O blocks.

What is the difference between IC693CMM301 and IC693CMM302?

The GCM+ (IC693CMM302) is an advanced version of the standard GCM. While they can coexist on the same bus, they cannot be installed together in the same PLC rack.

What is the maximum data capacity supported?

The module supports 128 bytes of data for sending and receiving.
