GE Fanuc Series 90-70 IC697CPM914 CPU | 32-bit

Product Overview

The GE Fanuc IC697CPM914 is a powerful 32-bit central processing unit utilizing the 80486DX architecture. Designed specifically for the Series 90-70 PLC system, this 32 MHz module provides the speed and precision required for demanding industrial applications. By eliminating physical DIP switches in favor of software-based configuration, it simplifies the setup process while offering advanced capabilities like floating-point math for high-accuracy process control and motion applications.

Technical Configuration

This CPU module is optimized for high-density I/O and rapid data processing:

• Microprocessor: 80486DX 32-bit processor running at 32 MHz.
• Memory Storage: 512KB SRAM with lithium battery backup (6-month data retention).
• I/O Capacity: Supports up to 8,000 analog I/O or up to 12,000 mixed I/O points for large-scale control.
• Communication: 15-pin D-type serial port supporting RS-422/RS-485 and speeds up to 115,200 bps.

Technical Specifications

Installation & Maintenance

Mounting: The IC697CPM914 is a single-slot module that integrates directly into the Series 90-70 rack system. Despite its powerful 32-bit architecture, it maintains a lightweight profile of 0.36 kg. Ensure the module is seated firmly in the backplane before securing the mounting screws.

Battery Care: The lithium battery is critical for maintaining program memory during power-down cycles. With a 6-month retention rating, the battery should be replaced on a regular maintenance schedule to prevent the loss of 512KB of SRAM data.

Engineering Advantages

• Floating-Point Precision: Native 80486DX math support enables high-precision arithmetic without external math coprocessors.
• Advanced Connectivity: Compatible with Ethernet programming (10Mbps) and RS-232 converters for modern PC interfacing.
• Software Configuration: Eliminates mechanical DIP switch errors; all settings are managed via the GE programming software.
