GE IC693CMM311N Communications Coprocessor Module

Description

Product Introduction & Positioning
The IC693CMM311N Communications Coprocessor Module provides enhanced communication capabilities for Series 90-30 CPUs. It acts as a dedicated bridge for advanced data exchange, enabling multiple serial ports and protocol support while coordinating with the main controller. This module fits into the backplane with other I/O and processing modules, expanding the system’s networking reach without burdening the primary CPU. Engineers appreciate the separation of communication tasks, which improves system responsiveness and scalability in retrofit projects or new installations. The model IC693CMM311N is a trusted choice for engineers who need reliable, modular communications within GE Fanuc automation environments.

Key Technical Features & Functional Benefits
The IC693CMM311N centers on high-performance data communication for Series 90-30 systems. It typically offers two serial ports (RS-232/RS-485 options) and supports multiple protocols such as CCM and SNP, enabling flexible integration with peripheral devices and external networks. The coprocessor architecture helps offload protocol handling from the main CPU, improving overall system throughput and responsiveness. Robust diagnostic indicators help pinpoint port status, bus activity, and fault conditions, which speeds maintenance and reduces downtime. With this module, engineers can extend network reach, bridge legacy devices to newer supervisory systems, and maintain reliable data flows across complex automation layouts.
