GE Fanuc IC697CPU772 CPU Module 512KB

Product Introduction

The GE Fanuc IC697CPU772 is a powerful processor module designed for the Series 90-70 programmable logic controller family. This single-slot CPU occupies minimal rack space while delivering substantial processing capability. It uses an 80C186 microprocessor with a 12 MHz system clock, ensuring efficient execution of control logic. Furthermore, the IC697CPU772 supports floating-point operations, making it suitable for applications involving complex calculations and analog signal processing. With its expandable memory architecture, this module adapts to both small and large-scale automation projects.

Memory Capacity and Expansion

A key feature of the GE Fanuc IC697CPU772 is its support for up to 512 kilobytes of user memory. The base module provides onboard storage, and you can further expand it using CMOS memory modules in 64 KB, 128 KB, 256 KB, or 512 KB capacities. These expansion modules install directly onto the CPU, eliminating the need for extra rack slots. Consequently, you can scale memory resources without sacrificing valuable chassis space. The system memory can be partitioned for program logic, register data, and analog I/O processing, offering flexibility for diverse application requirements.

Power and Battery Backup

The IC697CPU772 draws 1.2 Amps from the 5 Volts DC bus, which includes the current consumed by any attached expansion memory. This power requirement is modest and well within the capacity of standard Series 90-70 power supplies. A replaceable lithium battery provides backup power to both program and data memory when the main system power is removed. This battery ensures that your critical logic and configuration remain intact during unexpected outages. To maintain optimal performance, always remove the old battery before installing a new one.

Communication and Configuration

An integrated serial port on the GE Fanuc IC697CPU772 allows connection to a serial programmer for configuration and monitoring. You can also configure this CPU using MS-DOS or Microsoft Windows-based programming tools, giving you flexibility in your engineering environment. At boot-up, the module automatically verifies the actual hardware configuration against the programmed settings. Additionally, the system performs periodic checks during normal operation to detect any deviations. This self-diagnostic feature enhances system reliability and simplifies troubleshooting.

Compatibility and System Integration

The IC697CPU772 is fully compatible with the GE Fanuc Series 90-70 PLC family, which includes a wide range of racks, power supplies, I/O systems, and optional modules. It works seamlessly with Genius I/O and various communication modules. This broad compatibility makes it easy to integrate into existing installations or to build new systems from scratch. Moreover, the CPU supports remote module control and backplane communication, enabling distributed control architectures. Whether you are upgrading an older system or designing a new one, the GE Fanuc IC697CPU772 offers a dependable solution.

Installation and Operational Guidelines

Installing the IC697CPU772 is straightforward. Simply insert the module into any available slot in the Series 90-70 rack. Ensure that the power supply is turned off during installation to prevent damage. Connect the backup battery to the designated connector before powering up the system. The CPU supports floating-point math and real-time application control, making it ideal for material handling, process automation, and machine control. Its robust design ensures stable operation even in challenging industrial environments.
