GE Fanuc IC697CPM924 | 64 MHz 32-bit Microprocessor

Product Overview

The GE Fanuc IC697CPM924 is a high-performance Central Processing Module (CPM) designed for the Series 90-70 PLC family. Featuring a powerful 64 MHz 32-bit microprocessor and 1 MB of onboard user memory, this module is engineered to handle complex logic and high-speed data processing. It is a cornerstone for large-scale industrial applications requiring precise floating-point calculations and rapid instruction execution.

Core Computational Power

High-Speed Processing

The IC697CPM924 executes over 0.2 million Boolean instructions per second, making it ideal for time-critical automation. With its integrated floating-point support, it delivers enhanced accuracy for mathematical modeling and PID control loops within the Series 90-70 architecture.

Memory & Data Retention

This module provides 1 MB of RAM, allowing for program storage up to 800 KB. To protect critical logic, it features a lithium battery backup that retains memory for up to 6 months without external power, ensuring system parameters are preserved during maintenance or outages.

Technical Specifications

Installation & Connectivity

Communication Interface

The module includes an integrated RS-232 serial port for direct programming and monitoring. For broader integration, it supports optional Ethernet modules, allowing the CPU to communicate with supervisory HMI and SCADA systems over high-speed networks.

Operating Environment

To maintain peak performance at the maximum ambient temperature of 60°C (140°F), a minimum airflow of 100 LFM (Linear Feet per Minute) is required. Always ensure the backplane power is disconnected before installing or removing the CPU module to prevent hardware damage.

Engineering Advantages

The IC697CPM924 represents the pinnacle of the Series 90-70 family's reliability. Its high-precision clock (accurate to 3.5 seconds per day) is vital for event logging and synchronized process steps. The parallel port bus interface allows for rapid data throughput across the backplane, supporting complex I/O configurations without communication bottlenecks.
