Product Introduction
GE IC693NIU004-FC is an Ethernet Network Interface Unit for Series 90-30 PLCs, turning remote racks into EGD drops over Ethernet. It handles discrete and analog I/O exchange with the host CPU without proprietary cabling.
Requires high-capacity PSU (IC693PWR330+ series)—standard supplies overload at 7.4 W draw. Field setups use it for distributed drops up to 100 m from control room. Program via CIMPLICITY Machine Edition; verify firmware -FC compatibility with Logic Developer.icdn.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No network OK LED, solid red | PSU overload or wrong capacity | ✅ High | Measure backplane current >1.48 A at 5 V pins with clamp meter | Swap to IC693PWR330; calc total rack load +20% buffer |
| EGD comms timeout from host | IP conflict or cable fault | ✅ High | Ping NIU IP from PC; check RJ-45 link lights | Static IP via serial; test Cat5e <100 m; reboot pushbutton |
| I/O points unresponsive in PLC | Mapping mismatch %I/%Q size | ✅ Medium | Logicmate status: verify 2048 pt exchange config | Reload EGD map in CPE410; match device ID exactly |
| Battery low alarm after outage | Missing external IC693ACC302 | ❌ Low | Read %SA battery bit; voltage <2.8 V on pins | Install external pack for 15 mo holdup; cycle power |
| RS-485 SNP fails on programming | Baud mismatch or null modem | ✅ Low | HyperTerminal 19.2k; no echo on loopback | Cross pins 2-3 on RJ-11; baud 19.2k 8N1 standard |
Dump EGD stats and MAC address photo to support. NIUs drop from power glitches 80% of time—PSU first.

Frequently Asked Questions (FAQ)
Does IC693NIU004-FC need high-capacity power supply?
Yes, minimum IC693PWR330/331/332. Draws 1.48 A at 5 V—standard PSUs trip. I’ve yanked one thinking dead module; it was brownout.
Firmware -FC—what changes?
Likely EGD IO fix or TCP stack patch over base NIU004. Read label; matches host CPE firmware or expect handshake fails.
Max distance to host PLC?
Ethernet standard: 100 m Cat5e to switch. Fiber media converters extend to km. No drop seen at 95 m full load.
Hot-plug into live rack?
No—backplane arcs fry pins. Power down, insert in slot 1 of remote base. Latch clicks firm or reseat.
❗ Top gotcha on startup?
❗ Forgetting to enable EGD in config—CIMPLICITY SP3+ required. Host sees rack but zero I/O flow. Wasted half-shift debugging once.
Condition and testing?
New Surplus: OEM stock, bench-tested EGD ping to host at 100 Mbps. Continuity on all ports; no bent pins. Reports ready.
Warranty, lead time?
1-year on DOA. In stock, ships post power-cycle test. Zero delay unless rack surge.
