Product Introduction
GE IC695CPU310-GW is a PACSystems RX3i CPU module used as the main processor in GE Fanuc and Emerson control systems. It handles logic execution, serial communications, and RX3i backplane coordination in industrial automation applications.
It is typically selected for replacement work, spare inventory, and RX3i upgrades where the original CPU310 platform is already in service. The practical value is its mix of 10 MB user memory, dual serial ports, and support for legacy Series 90-30 remote I/O migration.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No status LEDs after power-up | Backplane power missing or CPU seated badly | High | Measure 5 VDC at the rack and inspect CPU LEDs | Check power and seating before replacing the module |
| RUN light will not stay on | Logic fault, project issue, or memory problem | High | Review fault codes and try a known-good project load | Reload the application or replace if faults persist |
| Serial comms fail on both ports | Wrong baud, protocol, or damaged serial interface | High | Verify RS-232 or RS-485 settings and cable pinout | Confirm configuration before declaring CPU failure |
| RX3i rack not recognized | Backplane or rack compatibility issue | Medium | Confirm IC695CHS012 or IC695CHS016 use and inspect connector pins | Verify rack type and seating first |
| Intermittent resets | Power sag or thermal issue | Medium | Monitor supply voltage under load and cabinet temperature during operation | Stabilize power and cooling before replacing hardware |
| I/O data is stale | Network mapping or EGD/SRTP configuration problem | Medium | Verify comms task setup and exchange tables | Recheck network configuration before swapping CPU |
If the fault remains unclear, send photos of the LED pattern, rack layout, and diagnostic logs to technical support.

Frequently Asked Questions
Q: Is IC695CPU310-GW a CPU or just an Ethernet module?
It is a CPU. It handles logic execution and also includes embedded serial communication.
Q: Does it support dual serial ports?
Yes. The CPU310 platform is documented with two serial ports.
Q: Can I hot-swap this CPU?
No. Power it down first. Live removal risks data corruption and backplane damage.
Q: What protocols matter most on this unit?
Industrial Ethernet, Modbus TCP/IP, SRTP, and EGD are the key ones buyers usually care about.
Q: Is this part obsolete?
In practice, yes, it is mostly a secondary-market item now. That is why stock usually shows up as surplus rather than current OEM production.
Q: Why does the same model sometimes show different suffixes?
Different suffixes can reflect hardware revision or release variation. Match the exact suffix on your old unit before ordering.
Q: What should I verify before installation?
Confirm rack power, IP settings, suffix, battery status, and whether your existing project expects the same communication setup. One wrong setting can look like a bad CPU when the hardware is fine.
