GE IC697CPM925-AB 64 MHz Floating Point CPU (Single Slot)

Description

In high-stakes production lines demanding massive data crunching and split-second synchronization, a top-tier CPU dictates whether processes hum or halt. Envision a pharmaceutical compounding facility juggling 16,000 I/O points for precise blending, filtration, and packaging across remote Genius drops—GE IC697CPM925-AB drives it all as the single-slot powerhouse in Series 90-70 PLCs, leveraging 64 MHz floating-point muscle to slash boolean execution to 0.2 microseconds in industrial automation. It confronts scaling pains in aerospace component testing, where vibration sensors and servo axes span buildings, or semiconductor wafer fabs tracking etchant flows over noisy networks, ensuring math-intensive loops like PID tuning stay ahead of variability.

Teams install GE IC697CPM925-AB when lower CPUs bottleneck complex recipes, supporting IC660/661 remote racks up to 7,500 feet while backing 2MB RAM for sprawling data tables and historians. Front LEDs track RUN/STOP, faults, and memory status, arming shifts with instant visuals, while the AB firmware revision hones OS stability for fewer boot hiccups. In control systems overhauls for oil/gas separators or automotive body-in-white lines, it mates legacy backplanes with expanded coprocessors, delivering password protection and remote keyswitch for secure, vendor-agnostic growth

Product Introduction & Positioning

GE IC697CPM925-AB operates as a 64 MHz 80486DX2 Floating Point Central Processing Unit for GE Fanuc Series 90-70 systems, claiming just one slot in standard or VME racks to run ladder logic, advanced math, and interrupts via MS-DOS/Windows programmers over SNP or Ethernet. User-defined splits of 2MB battery RAM fuel programs up to 1MB alongside registers, with backplane mastery over I/O scanners, LANs, and high-speed modules. Architecturally, it leads simplex/dual setups in control systems, prioritizing real-time scans while freeing cycles for C-language subroutines or trends.

Integrators favor the AB tweaks for refined multi-tasking and VME C.1 compliance, sipping 3.0A at 5V without extras. It embraces all IC697 discretes/analogs plus IC66* remotes, with calendar clock for audit trails. For data-hungry sites, GE IC697CPM925-AB stands as the high-octane core, amplifying throughput where speed spells profit.

Key Technical Features & Functional Benefits

Blazing at 0.2 µs per boolean, GE IC697CPM925-AB powers floating-point ops natively for buttery-smooth servo profiling or statistical process control in forging presses, outpacing 32 MHz siblings by double. RS-422/485 programmer port and four LEDs deliver foolproof status—OK solid in RUN, flicker on faults—while no jumpers mean pure software config via IC641 tools.

Toughened VME footprint endures industrial automation knocks, from 60°C ovens to EMI-laced welding bays, with AB firmware curbing rare scan overruns during I/O floods. It scales to 16K inputs/outputs (12K discrete, 8K analog mix) across local/remote, syncing seamlessly with Ethernet like IC697CMM741H or FIP controllers. Battery safeguards data through blackouts, accurate to ±2 sec/day.

Longevity shines via in-rack EPROM upgrades and 300,000-hour MTBF, letting crews retain passwords across personnel changes. Users rave about GE IC697CPM925-AB compressing commissioning from days to hours in greenfield builds.

Installation Notes & Maintenance Best Practices

Isolate rack power prior to slot 1 insertion of GE IC697CPM925-AB—attach fresh lithium battery (10-year shelf), toggle to STOP, unlock keyswitch. Firm backplane latch; expect 4-second self-test with steady OK LED on success. Link programmer serially with IC697CBL711 cable, terminator if last node; Ethernet needs CMM module first.

Retain data integrity swapping batteries powered-down every 4-6 months; flash AB firmware yearly via EPROM for scan tweaks amid growing I/O. Audit LEDs and %S fault bits monthly, especially post-power events—redundant testing biannually confirms handover. In dense racks, verify airflow prevents hotspots; operators log 99.999% uptime via disciplined EPROM rotations
