GE IC697CPM790

  • Product Introduction: This is a high-performance dual-port Ethernet communication module for the GE Fanuc 90-70 PLC platform. It provides two independent 10/100 Mbps Ethernet ports, enabling the PLC to connect to Ethernet/IP networks, Modbus TCP networks, or peer-to-peer Ethernet connections. The module includes an integrated 2-port Ethernet switch, allowing both ports to be used simultaneously on the same network segment. It supports up to 256 TCP/IP connections and is commonly used for SCADA communication, remote programming, and peer-to-peer PLC messaging.

  • Working Principle:
    • The module contains a dedicated Ethernet controller ASIC with an integrated TCP/IP stack. The GE CPU sends data to the module via the Genius Bus backplane. The Ethernet controller encapsulates this data into TCP/IP or UDP/IP packets and transmits them via the RJ-45 ports. The built-in switch allows both ports to operate on the same subnet simultaneously. Incoming packets are decapsulated and the payload is written to a dual-port RAM, which the CPU reads via the backplane bus.
  • Installation Requirements:
    • Mount in IC697 chassis (90-70 CPU rack)
    • Connect Ethernet cables (Cat5e or better, shielded recommended) to both RJ-45 ports
    • Configure IP address, subnet mask, and gateway via PLC programming software
    • Enable the Ethernet ports in the CPU configuration
    • Use shielded cable in high-EMI environments, ground shield at one end
  • Usage Precautions:
    • Use only Cat5e or Cat6 shielded twisted-pair cable
    • Do not exceed 100 meters cable length per segment
    • Set unique IP addresses for each module in the network
    • Enable the switch function only when both ports are on the same subnet
    • Do not connect Ethernet ports directly to the internet without a firewall
    • Update firmware regularly for security patches
