Description
Product Description
The GE IC693CMM311 is a Communications Coprocessor Module (CCM) for the GE Fanuc Series 90-30 PLC system. It provides advanced networking capabilities, enabling PLCs to exchange data with other controllers, SCADA systems, HMIs, and external devices. The module supports dual serial ports for RS-232/RS-485 connections and allows LAN communications using the CCM protocol.
This module is equipped with optical isolation between ports and the PLC logic for enhanced protection and reliability. Status LEDs provide real-time feedback on communication activity and module health, allowing for rapid troubleshooting. It fits directly into standard Series 90-30 rack slots, supporting flexible integration into existing PLC architectures.
