GE Fanuc IC697CPM915 | Series 90-70 PLC CPU Module 32MHz

Product Overview

The GE Fanuc IC697CPM915 is a robust central processing unit specifically engineered for the Series 90-70 PLC family. As a 32-bit processor running at 32 MHz, it provides the computational power necessary for sophisticated industrial automation tasks. This module is the "brain" of the PLC rack, managing high-speed I/O communication and executing complex control logic to ensure maximum uptime and operational efficiency in manufacturing and power generation environments.

Technical Configuration

This CPU module is designed for rapid integration and reliable performance:

• Memory Capacity: Features 1 MB of RAM for extensive program storage and data logging requirements.
• Communication: Equipped with one serial port supporting high-speed data exchange and local programming.
• Bus Interface: Plugs directly into the Series 90-70 bus for high-speed access to all discrete and analog I/O modules.

Technical Specifications

Installation & Maintenance

Rack Installation: The IC697CPM915 is a single-slot module that occupies any standard slot in a Series 90-70 rack. Ensure the rack power is off during insertion to protect the backplane pins. The unit weighs approximately 0.85 kg, fitting snugly into the guided rails of the chassis.

Status Monitoring: Integrated front-panel LEDs allow for quick visual diagnostics. The 'OK' LED confirms the CPU has passed its power-up self-test, while the 'RUN' LED indicates the processor is actively executing logic and communicating with the I/O network.

Engineering Advantages

• Proven Reliability: Part of the GE Fanuc Series 90-70 legacy, known for decades of stable performance in heavy industrial applications.
• Efficient Power Usage: Optimized for low heat dissipation despite its 2.8A draw, reducing the cooling load within the control cabinet.
• Large Memory Buffer: The 1MB RAM capacity allows for complex floating-point math and extensive PID loop control.

Technical FAQs

Q1: Does the IC697CPM915 require a battery?
A1: Yes, a lithium battery is required to maintain the 1MB of program RAM during power outages. It is recommended to replace the battery periodically.

Q2: Can I program this CPU using Proficy Machine Edition?
A2: Yes, the IC697CPM915 is compatible with modern GE programming software suites as well as legacy Logicmaster 90 software.

Q3: What is the primary cause of a 'FAIL' status on this module?
A3: A failure is often related to internal hardware self-test errors or an exhausted backup battery that has caused program corruption.
