4. Product Introduction
The GE IC693374-GP is a high-performance CPU module for the GE Fanuc Series 90-30 PLC platform, engineered for deterministic logic control and integrated network communications. It combines a 133 MHz embedded 586 CPU with 240 KB of configurable user memory to support ladder logic, register I/O blocks, and analog data within industrial automation programs.
With dual embedded 10/100 Mbps Ethernet ports and an RS-485 serial port supporting SNP/SNPX communication protocols, the IC693374-GP provides flexible connectivity for SCADA, HMIs, and peer-to-peer PLC communication. Its single-slot design fits standard Series 90-30 baseplates, and verified OEM condition stock ensures reliable performance for production systems and spare parts inventory.
5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No LEDs when powered | No backplane +5 V supply | ✅ High | Measure +5 V DC at CPU slot with meter | Confirm PSU output and fuse before suspecting CPU |
| RUN fails to latch | Battery/program memory lost | ⚠️ Medium | Inspect battery status LEDs | Replace battery, reload program via PME |
| Ethernet link lights off | Cabling or switch mismatch | ⚠️ Medium | Check RJ45 link/activity LEDs | Swap known good cable and confirm switch config |
| Serial comm not responding | Wrong SNP protocol setting | ⚠️ Medium | Use serial tester to verify signal | Adjust SNP/SNPX config in software |
| PLC logic not executing as expected | Incorrect memory block usage | ❌ Low | Review memory allocation | Verify %R/%AI/%AO config in project |
Pro tip: With Series 90-30 CPUs like the IC693374-GP, scan issues attributed to the CPU are often a result of power loss, memory protect settings, or mismatched communication parameters, not a hardware defect. Check power rails and LED codes first.
6. Frequently Asked Questions (FAQ)
Q1: How does IC693374-GP differ from other 90-30 CPUs?
A: The “-GP” suffix denotes a specific revision of CPU374, featuring the same 133 MHz embedded 586 core and dual Ethernet ports but often with updated internal firmware and factory test action. Functionally, it matches other CPU374 variants in slot compatibility and control performance.
Q2: What software do I need to program this CPU?
A: Use Proficy Machine Edition or legacy Logicmaster/VersaPro for 90-30. Confirm your version supports CPU374 Series 90-30 before attempting downloads/uploads.
Q3: Can I use this CPU in remote racks?
A: Yes — Series 90-30 allows up to 8 total baseplates (1 local CPU + up to 7 expansion/remote) with proper cabling and configuration.
Q4: Are the two Ethernet ports independent?
A: Yes — they are 10/100 Mbps auto-sensing and can link to HMIs, SCADA, or peer PLC CPUs for distributed control and data tasks.
Q5: What protocols are supported on serial/ethernet?
A: Standard Series 90-30 SNP/SNPX over RS-485, and Ethernet handles industry protocols compatible with GE control networks.
Q6: Why might this be priced below current factory pricing?
A: This part is legacy and discontinued; most stock is New Surplus or Refurbished Tested, not active OEM production. Confirm condition and testing SOP with your supplier.
