Brief Product Description

GE IC697CPX772 is a high-performance 96MHz 32-bit floating-point CPU processor module for GE Fanuc Series 90-70 PLC systems. Equipped with 512K user memory and three built-in serial ports, it serves as the core controller of the 90-70 rack to execute control logic, process floating-point calculations and handle I/O scanning. It supports up to 2000 discrete I/O points and analog signal processing, and can communicate with programming terminals, HMIs and other intelligent modules via SNP protocol. Featuring industrial-grade hardware, watchdog protection and comprehensive self-diagnosis, it is designed for complex process control applications requiring high reliability. Fully tested surplus and refurbished GE IC697CPX772 modules are available for legacy Series 90-70 PLC maintenance, CPU replacement and industrial automation retrofit projects.

FAQ (Frequently Asked Questions)

• Q: PLC cannot enter run mode or frequent major fault alarms after installing IC697CPX772?
  A: Verify firmware and program compatibility, check memory backup battery, inspect backplane connector, confirm rack power quality and eliminate grounding or EMI interference.
• Q: Does GE IC697CPX772 support hot-swap replacement?
  A: Hot swap is not supported. Back up all PLC programs and parameters, cut off rack power and perform lockout-tagout before replacement to prevent unexpected equipment action and program loss.
• Q: What system is IC697CPX772 designed for?
  A: It is a dedicated CPU processor module for GE Fanuc Series 90-70 PLC platform.
• Q: What communication protocol does its serial port use?
  A: The three onboard serial ports support SNP protocol for programming and serial data communication.
• Q: Is GE IC697CPX772 available for new automation projects?
  A: This legacy Series 90-70 CPU module is end-of-life for new installations. Only fully tested surplus and refurbished units are supplied for existing PLC system maintenance and retrofits.
