GE Fanuc IC693CPU350-EK Series 90-30 CPU Module
The GE Fanuc IC693CPU350-EK, also cataloged as the IC693CPU350 Central Processing Unit, operates as a dedicated hardware component for logic execution and backplane I/O scanning within GE Fanuc Series 90-30 PLC systems. Occupying a single slot on the baseplate, the module processes ladder logic routines at 25 MHz via an 80386EX processor to coordinate local and expansion rack data flow across the automation network.

Backplane Bus Communication Velocity & Firmware Flash Compatibility
The IC693CPU350-EK maintains high backplane bus communication velocity during intensive I/O scan sequences by decoupling serial protocol execution from core boolean logic processing. System operational capability relies on firmware flash compatibility within the Series 90-30 ecosystem, ensuring execution of logic instructions across expanded I/O density configurations without degrading real-time task responsiveness.
Frequently Asked Questions
Q: How is logic retention preserved on the IC693CPU350-EK during primary power disruption?
A: RAM contents and system register states are sustained by a lithium backup battery located in the power supply module connected via the backplane bus.
Q: Can the serial ports on the IC693CPU350-EK handle non-proprietary communication protocols?
A: Yes, the built-in serial ports support configurable Modbus RTU and ASCII protocols alongside the standard GE Fanuc SNP protocol for interface with third-party devices and HMIs.
Field Installation Guidelines
- Verify backplane power supply capacity prior to module insertion to ensure the 670 mA at 5 VDC logic bus requirement is met.
- Keep the main baseplate power disconnected when installing or replacing the processor module in Slot 1.
- Secure the lithium battery connection on the power supply module before powering down the rack to prevent user RAM corruption.
- Use shielded twisted-pair cabling for all RS-485 serial connections and terminate the shield ground at a single cabinet earth point.
