IC697CPM925 belongs to the GE Fanuc Series 90-70 series, a single slot 32-bit floating-point CPU module with a processor of 80486DX2, a main frequency of 64MHz, a Boolean instruction execution speed of 0.4 microseconds per instruction, supports floating-point operations, firmware stored in onboard Flash, and can be upgraded online without the need to replace EPROM chips Qualitrol.

User logic memory 1MB lithium battery backup RAM, lithium battery model IC697ACC771, battery shelf life of 10 years at 20 ℃ environment; When the whole machine is powered off, the RAM program and data storage time are nominally 6 months. The module is equipped with a real-time clock, with a maximum daily error of 3.5 seconds and a maximum accuracy of 0.01% for the time timer. The module is equipped with a hardware memory protection key switch, coupled with software password protection, to prevent the program from being mistakenly modified.

I/O processing capability, with a maximum of 12K discrete I/O points, capable of any mixed input/output configuration; Maximum analog I/O of 8K points. Compatible with all IC697 series local I/O and intelligent communication coprocessor modules, while supporting Genius remote I/O IC660/IC661 series. Exchange data with other modules in the rack through the VME C. 1 standard backplane.

Communication configuration, onboard one RS422/RS485 serial programming port, supporting SNP protocol, used for downloading programs and monitoring on programming software; The CPU itself does not have an Ethernet port, and Ethernet functionality requires an external LAN communication module for expansion. The programming software supports MS-DOS and early versions of Windows software.

The backplane is powered by 5VDC and has a nominal current of 3.3A. The front panel of the module is equipped with multiple sets of LED status indicator lights, including OK, RUN, ENABLED, and FAILT, which respectively display self-test normal, running status, enable, and fault alarm. Faults can be reported to the PLC system and system diagnostic information can be recorded.

Under temperature conditions, the working temperature is 0-40 ℃ without forced air cooling; When equipped with a rack fan to provide 70CFM forced air cooling, the operating temperature can be extended to 0-60 ℃; Storage temperature -40-85 ℃, humidity 5-95%, no condensation. The physical dimensions are 177.8mm × 120.7mm × 50.8mm, and the weight is approximately 0.5kg.

This CPU supports multiple program runs, with a maximum of 512KB per program, and only allows one ladder diagram/SFC main program. Can be used for redundant rack IC697CHS770 to implement dual CPU hot standby system.
