GE Fanuc IC697CPU782 | 16MHz Central Processing Unit

Product Overview

The IC697CPU782 is a powerful 32-bit Central Processing Unit (CPU) designed for the GE Fanuc Series 90-70 PLC system. Driven by a 16 MHz 80386DX microprocessor, this unit is engineered for high-speed logic execution and complex industrial data handling. It offers a boolean execution speed of just 0.4 microseconds, making it a premier choice for time-critical automation tasks. With support for up to 512 Kbytes of battery-backed expansion memory and 12K total I/O points, this CPU provides the scalability and processing power required for large-scale factory automation and process control systems.

Technical Configuration

Core Engineering Advantages

This CPU architecture emphasizes flexibility and security in high-stakes environments. It features software-based configuration, eliminating the need for physical DIP switches or jumpers, which simplifies setup and reduces hardware failure points. Security is maintained through password-controlled access and a physical keyswitch for memory protection. The system also integrates an RS422/RS485 compatible SNP port for seamless programmer attachment and is fully compliant with VME standard C.1 for enhanced system interoperability.

Technical Specifications

Installation & Maintenance Guide

The module occupies a single slot in the Series 90-70 rack. Before installation, ensure the battery is properly connected to maintain memory retention during power cycles; the battery features a 10-year shelf life at 20°C. Programming can be performed using MS-DOS or Windows-based software (Windows 95/NT) via Ethernet TCP/IP or the local SNP port. Monitor the four status LEDs during startup to verify system health. No internal jumpers are required; all hardware parameters are defined through the software configuration utility.

Engineering Advantages

• High-Speed Processing: The 80386DX core ensures rapid handling of both discrete and complex analog calculations.
• Robust Memory Management: Supports battery-backed retention for up to 6 months, securing critical user logic and register data during outages.
• VME Compatibility: Adherence to VME C.1 standards allows for seamless integration within standardized industrial backplanes.
• Lightweight Design: At a weight of 0.85 kg, the module remains easy to handle and install while offering high-density processing power.

Technical FAQs

Q1: What programming software is compatible with this CPU?
A1: It is compatible with GE Fanuc programming software running on MS-DOS or Windows (specifically optimized for Windows 95 and Windows NT).

Q2: How is memory protection handled?
A2: Data security is managed through a multi-layer approach including software passwords and a physical three-position operation mode keyswitch to prevent unauthorized memory changes.

Q3: Does the 1.6 Amp power requirement include expansion memory?
A3: Yes, the 1.6 Amp draw from the 5V bus accounts for the CPU and any expansion memory installed in the same slot.
