Product Introduction
The GE IC693CMM311 is a Communications Coprocessor Module designed for the GE Fanuc Series 90-30 programmable logic controller (PLC) system. This module significantly enhances the communication capabilities of a PLC by providing an additional serial port and offloading communication processing from the main CPU. It is used to enable serial communication between the Series 90-30 PLC and external devices such as computers, HMIs (Human-Machine Interfaces), bar code readers, and other serial-enabled equipment.
The IC693CMM311 supports Modbus RTU master and slave protocols, as well as user-defined protocols, making it highly versatile in multi-device environments. By integrating this module, users can configure their automation systems to communicate with a wide variety of third-party devices over RS-232 or RS-485.
Engineered for reliability and performance in industrial settings, the CMM311 is a robust and flexible solution for applications requiring advanced serial communication.
