Developed for versatile data communication, the GE Fanuc Emerson IC693CMM311 is a communication coprocessor module from the Series 90-30 Programmable Logic Controller (PAC) family. It features two (2) configurable communication ports—Port 1 supports RS-232, while Port 2 can be configured for RS-232, RS-422, or RS-485 electrical standards—providing flexibility for various industrial networking requirements. The module supports multiple communication protocols, including CCM, RTU, and SNP, enabling reliable data exchange between PLCs and external devices. Designed for stable performance and broad compatibility, the IC693CMM311 may possibly be implemented across automation systems in North America, Europe, Asia, and other worldwide environments utilizing GE Fanuc Series 90-30 architectures.
