GE IC698CMX016-ED

The GE IC698CMX016-ED is a Control Memory Xchange (CMX) module belonging to the GE Fanuc (now Emerson Automation) PACSystems RX7i series. Specifically designed for industrial automation systems, it enables high-speed transmission and sharing of deterministic data between different PLCs. Its core function lies in achieving real-time data synchronization among multiple nodes via a fiber optic network, and it finds extensive application in distributed control systems across manufacturing, energy, chemical, and other sectors.
