4. Product Introduction
The IC698CPE030 is a 600 MHz Pentium-M CPU for the GE Fanuc / Emerson PACSystems RX7i platform. It provides 64 MB of battery-backed user RAM and 64 MB of non-volatile flash, along with an embedded 10/100 Mbps Ethernet interface and dual serial ports.
Designed for real-time control of machines, processes, and material-handling systems, it communicates with I/O over the VME64 backplane and supports programming and HMI connections via Ethernet or serial SNP. Boolean execution is typically 0.069 ms per 1000 contacts/coils. A fan tray is required for operation above 50 °C.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No LEDs / CPU will not power up | Missing +5 V or backplane fault | ✅ High | Measure +5 V at the backplane; check rack power supply | Verify power and seating before replacing CPU |
| CPU OK LED off / Fault indicated | Hardware fault or configuration error | ✅ High | Read diagnostic buffer in programmer software | Clear faults if possible; persistent faults usually require replacement |
| Memory loss after power cycle | Battery depleted or missing | ✅ High | Check battery status and age | Replace battery per GFK-2741 guidelines |
| Overtemperature / reduced performance | Ambient >50 °C without fan tray | ✅ High | Confirm fan tray operation and airflow | Install fan tray for operation up to 60 °C |
| Ethernet link down | Cable, switch, or port issue | ⚠️ Medium | Check LINK LED; test with known-good cable | Verify network settings and cable integrity |
| Serial ports unresponsive | Baud rate or protocol mismatch | ⚠️ Medium | Match serial parameters to previous configuration | Use correct cable and settings |
If basic power, battery, and cooling checks do not resolve the issue, replace the IC698CPE030. Always power the rack down and follow ESD procedures when handling the module.
6. Frequently Asked Questions (FAQ)
Q: What is the processor speed and memory of the IC698CPE030? A: 600 MHz Pentium-M processor with 64 MB battery-backed RAM and 64 MB non-volatile flash.
Q: Does it have built-in Ethernet? A: Yes. It includes an embedded auto-sensing 10/100 Mbps Ethernet port supporting SRTP, Ethernet Global Data (EGD), Modbus TCP, and web/FTP services.
Q: What is the operating temperature range? A: 0 to 50 °C without a fan tray. With a compatible fan tray the range extends to 60 °C.
Q: Is the RX7i platform still in production? A: The RX7i platform is mature/legacy. Remaining IC698CPE030 units are new surplus or refurbished. Long-term projects should evaluate migration paths to current PACSystems controllers.
Q: What serial protocols does it support? A: Modbus RTU Slave, SNP, and Serial I/O on the RS-232 and RS-485 ports.
Q: Why is a new-surplus IC698CPE030 often priced lower than current RX3i CPUs? A: It is an end-of-life RX7i component. New-surplus stock comes from project overstock, is fully tested, and is sold at a reduced price while still carrying warranty. Condition is clearly stated as New Original / New Surplus.
Q: How much current does it draw from the +5 V bus? A: 3.2 A nominal. Always calculate total rack load and leave adequate margin on the power supply
