Description
Description
The IC697CPM925 is a high-performance single-slot central processing unit (CPU) module developed by GE Fanuc (now integrated into Emerson’s industrial automation portfolio) for the Series 90-70 PLC system. As the “brain” of the automation system, it executes complex control logic, manages data exchange between modules, and enables real-time oversight of industrial processes—from machine operation to material handling.
Application Scenarios
A mid-sized chemical processing plant in Texas struggled with production bottlenecks due to its outdated Series 90-70 CPU: slow logic execution (1.2 microseconds per boolean function) caused delays in regulating 6 reactor temperature controllers, leading to 12+ hours of monthly unplanned downtime and $30,000 in wasted batches. The plant also needed to add 4,000 new I/O points for expanded sensor monitoring but was limited by the old CPU’s 5K I/O capacity. After upgrading to the IC697CPM925, its 0.4-microsecond boolean execution speed cut control response time by 67%, stabilizing reactor temperatures within ±0.5°C. The module’s 12K digital I/O capacity easily accommodated the new sensors without additional hardware. Within three months, downtime dropped to 1.8 hours monthly, and batch waste fell by 45%. This scenario highlights how the IC697CPM925 solves core pain points of slow processing speed and limited scalability in process-critical environments.

IC697CPM925
Technical Principles and Innovative Values
Innovation Point 1: High-Speed Processing for Time-Critical Tasks – Equipped with a 64MHz 80486DX2 processor, the IC697CPM925 executes boolean functions 3x faster than its predecessor (IC697CPM915, 32MHz). This speed is critical for applications like automotive robotic welding, where a Midwest plant used the IC697CPM925 to synchronize 15 robots with 2ms precision, cutting weld defect rates by 30%.
Innovation Point 2: Scalable I/O Capacity for Growing Systems – Supporting 12K digital and 8K analog I/O points, the module eliminates the need for multiple CPU expansions in large facilities. A water treatment plant in Florida replaced two lower-capacity CPUs with one IC697CPM925, reducing system complexity and saving $8,000 in hardware costs.
Innovation Point 3: Maintenance-Friendly Memory and Firmware Design – The 1MB battery-backed RAM retains critical data during power outages, while flash firmware allows updates via a floppy disk (no module disassembly required). A pharmaceutical plant in New Jersey reported 90% faster firmware updates compared to EPROM-based CPUs, minimizing production downtime.
Application Cases and Industry Value
Automotive Parts Stamping Plant (Michigan) – The plant’s stamping line relied on 8 presses controlled by an outdated CPU, which struggled to process 6,000 I/O signals from pressure sensors and conveyor belts. This caused 8 hours of weekly downtime due to delayed press actuation. After installing the IC697CPM925, its 64MHz processor handled the I/O load seamlessly, and the 12K I/O capacity left room for 2 new presses. Downtime dropped to 1 hour weekly, and production output increased by 15%. Maintenance teams noted, “The memory protect switch also prevented accidental program changes, a huge win for safety.”
Pharmaceutical Packaging Facility (New Jersey) – The facility needed precise control of 10 filling machines (requiring floating-point calculations for dosage accuracy) and compliance with data security regulations. The old CPU lacked floating-point capabilities and password protection. The IC697CPM925’s floating-point processing reduced dosage variation from ±2% to ±0.3%, meeting FDA standards, while password security simplified audit trails. The plant saved $25,000 in batch rework costs and passed its next regulatory inspection with zero findings.

Installation, Maintenance, and Full-Cycle Support
Installing the IC697CPM925 is designed for minimal disruption. Ensure the rack power is off, set the memory protect key switch to “Off” and the run/stop switch to “Stop”, then slide the module into Slot 1 of the Series 90-70 rack—no tools are needed. Connect the backplane power, and the module’s “OK” LED illuminates once powered. A 70 CFM fan is required for cooling in high-temperature environments, but commissioning takes less than 30 minutes with compatible software like Proficy Machine Edition.
Routine maintenance is straightforward: inspect the battery annually (replace with IC1ACC697 if low) and verify the “RUN” LED is solid green during operation. The manual key switch lets you lock program access, and firmware updates are done via a floppy disk—simply connect a computer to the serial port and run the loader software. In case of faults, the module’s diagnostic LEDs (e.g., “FAULT” for memory errors) isolate issues in minutes, avoiding full system shutdowns.
