Brief Product Description

The GE Fanuc IC697CPU772 is a 12 MHz central processing unit for the Series 90-70 PLC, featuring advanced floating-point math capabilities. This expandable processor provides reliable control logic execution and flexible memory management for complex industrial automation environments.

​Product Description

High-Precision Processing Power

The GE Fanuc IC697CPU772 functions as the primary control intelligence for the Series 90-70 PLC platform. Driven by an 80C186 microprocessor operating at a 12 MHz system clock, this unit delivers the computational speed required for sophisticated industrial tasks. Specifically, the module supports hardware-based floating-point operations, allowing it to perform complex mathematical calculations with higher precision than standard integer-based processors. This capability makes the CPU772 particularly effective for motion control, PID loops, and chemical process management where accuracy is paramount.

Scalable Memory and Data Integrity

Engineered for flexibility, the IC697CPU772 offers a versatile memory architecture that adapts to the size of your control program. While the base unit provides essential storage, users can significantly increase capacity by installing CMOS expansion memory modules in sizes of 64 KB, 128 KB, 256 KB, or 512 KB. To ensure that logic and register data remain secure during a power outage, the module utilizes a replaceable lithium battery for CMOS backup. Furthermore, the CPU performs an automated configuration check upon every startup, which effectively prevents the system from running if it detects a hardware mismatch or corrupted setup.

Integration and Communication Features

The IC697CPU772 occupies a single slot on the Series 90-70 backplane, preserving valuable rack space for I/O and communication modules. For simplified commissioning and field diagnostics, the unit includes an integrated serial port that connects directly to Windows or MS-DOS based programming terminals. This interface allows engineers to upload logic, monitor real-time data, and force variables during troubleshooting. Because it belongs to the established Series 90-70 family, the module maintains full compatibility with a vast array of discrete, analog, and specialty I/O, ensuring a seamless upgrade path for aging control systems.
