GE Fanuc|IC693CMM311N|Communications Coprocessor Module
GE IC693CMM311N Series 90-30 Communications Coprocessor Module
GE IC693CMM311N is a communications coprocessor module for GE Fanuc Series 90-30 modular PLCs, supporting CCM, SNP, and Modbus RTU slave protocols via dual serial ports.
Features
Enables high-performance serial communication for CPUs 311, 313, 323, and above. Supports up to 4 modules per system when installed on CPU baseplate. Features configurable or default setup via software. Includes wye cable (IC693CBL305) for port separation.
Technical Specifications
- Compatibility: Modular CPUs only (311, 313, 323, 331+); not for embedded CPUs
- Communication Protocols: GE Fanuc CCM, SNP, Modbus RTU slave
-
Serial Ports: 2 independent ports
- Port 1: RS-232
- Port 2: RS-232 or RS-485
- Port Interface: Single connector with wye cable for port separation
- Firmware Update: Version 4.0+ (July 1996) resolves prior datagram cancellation issue between ports
- Power Consumption: 400 mA at +5 VDC
