Mechanical Data

‑ Weight：approx 0.32 kg ‑ Dimension：Series‑90‑30 standard single‑slot module form‑factor ‑ Handling note：ESD‑sensitive network circuit, anti‑static wrist‑strap mandatory during handling

Main Functions

1. Independent TCP/IP Ethernet co‑processor, undertake Ethernet communication tasks without occupying PLC CPU scan resources.
2. SRTP protocol: realize data read‑write between PLC and HMI, programming software, inter‑PLC data exchange.
3. Modbus‑TCP master/slave function: realize interconnection with third‑party Modbus‑TCP instruments, drives and upper monitoring system.
4. RJ‑11 debug port: local setting of IP address, subnet mask, gateway without Ethernet network.
5. LED status indication:   ‑ Green OK：Module power‑on and self‑test pass   ‑ LAN：Ethernet physical link status indicator   ‑ TX/RX：Network data sending/receiving activity indicator   ‑ FAULT：Module hardware / network communication fault alarm

Installation & Wiring Requirements

1. Cut off Series‑90‑30 PLC rack power before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling module.
2. Insert IC693CMM321 fully into PLC backplane slot and lock latch.
3. Use industrial shielded Ethernet cable for network wiring; separate network cables from high‑power cables; comply with industrial network wiring specification.
4. Complete protective grounding according to GE hardware manual.
5. After replacement: power‑on PLC, verify OK / LAN / FAULT LED status; set IP parameter via station‑manager port or software; download module configuration; perform Modbus‑TCP and SRTP communication test.
6. Replacement note: Verify CPU firmware compatibility; pay attention to network isolation, the module has no built‑in network encryption authentication; full system communication commissioning test mandatory before unit put‑into‑service。
