Developed by GE Fanuc Emerson, the IC693CMM321 Series 90-30 Ethernet Interface module enables efficient industrial communication and data exchange across automation networks. It includes three integrated connection types: one (1) RS-232 RJ-11 serial port functioning as the Station Manager Port, one (1) RS-485 15-pin D-type serial port used as the Software Loader Port, and one (1) AAUI port serving as the primary network interface. Supporting up to sixteen (16) simultaneous server connections, the module ensures stable Ethernet performance with built-in status indicators—OK, LAN, SER, and STAT—for real-time operational monitoring. It could potentially be utilized in automation facilities across North America, Europe, Asia, and other global regions operating Series 90-30 control architectures.
