In aging manufacturing floors where legacy PLCs still drive conveyors, presses, and fillers without the luxury of modern fiber or Gigabit switches, reliable Ethernet connectivity bridges old iron to SCADA, HMIs, or ERP without ripping out baseplates. Operators slot the GE IC693CMM321-KM into Series 90-30 racks for these industrial automation holdouts, enabling SRTP data exchanges that sync production counts, alarm pushes, or recipe downloads across mixed networks in food packaging, automotive assembly, or water pumping stations. Maintenance crews value it during brownfield squeezes, where upgrading to TCP/IP keeps downtime minimal while feeding historians or remote panels without custom middleware.
The GE IC693CMM321-KM handles real-world grit in factories with EMI from VFDs or welders, using external transceivers to tap 10Base-T coax for stable polls amid legacy hubs. Integrators deploy it in control systems pairing discrete I/O with supervisory oversight, dodging obsolescence by sustaining GE’s workhorse platform through phased modernizations. From discrete cells chasing throughput to process skids logging batches, it turns rack-mounted logic into networked assets that operators trust for shift-long reliability.
Product Introduction & Positioning
The GE IC693CMM321-KM is an Ethernet TCP/IP interface module for GE Fanuc Series 90-30 PLCs, occupying a single slot to connect the rack to 10 Mbps Ethernet LANs via AAUI port and external transceiver. It supports client/server SRTP for up to 16 connections, plus Station Manager access for diagnostics, positioning it as the network gateway in rack-based architectures linking CPUs to HMIs, DCS, or remote I/O
In a typical setup, the GE IC693CMM321-KM plugs beside power supplies and I/O, drawing backplane power while routing packets to CPU 6.50+ for full multi-server use—or limited single SRTP on older firmware. Engineers prize its drop-in simplicity for expanding comms without CPU swaps, using Logicmaster or VersaPro for config.
For system builders, the GE IC693CMM321-KM fits hybrid plants, translating PLC % registers to Ethernet globals while LEDs flag link health, easing troubleshooting in distributed control
Key Technical Features & Functional Benefits
Full-duplex capable with CRC error checking, the GE IC693CMM321-KM sustains 16 SRTP servers at 10 Mbps, buffering bursts to prevent drops during peak polls from CIMPLICITY or iFIX clients. Auto-negotiation and MAC filtering block unauthorized traffic, while timeout retries mask flaky hubs
Single-slot ruggedness suits dense 90-30 racks, with opto-isolated ports shrugging 1500V surges and conformal coats fending factory dust or washdowns; OK/LAN/SER/STAT LEDs pinpoint issues sans tools. RS-232 manager port runs diagnostics live, RS-485 loader flashes firmware offline
Backplane integration lets the GE IC693CMM321-KM share data seamlessly with IC693 CPUs, supporting 1-2 modules per rack for segmented nets; no redundancy but hot-pluggable with power cycled safely.
EEPROM configs persist reboots, with 100,000+ hour MTBF matching PLC overhauls; jumper-free setup streamlines field swaps.

Installation Notes & Maintenance Best Practices
Slide the GE IC693CMM321-KM into any non-CPU slot post-power-down, seating firmly and routing AAUI coax away from power cables—50 ohm terminators mandatory on segments. Pre-install, verify CPU firmware via loader port; static IP via Station Manager, testing pings before I/O tie-in. Transceiver mounts externally, grounded chassis-to-rack
Quarterly cycle LEDs for flicker-free glows, logging SRTP drops; annually reseat edge connector and flash latest firmware from SD—surplus refurbs match -KM rev exactly to dodge protocol quirks.dosupply
