Product Overview

The Emerson GE Fanuc IC697CPU711 is a central processing unit developed for Series 90-70 PLC architectures requiring stable, deterministic control performance. Acting as the core controller within the rack, this CPU executes user logic, manages I/O scanning, and coordinates communications across the backplane. Its architecture is designed for continuous operation in industrial environments where predictable cycle times and long-term reliability are essential.

The IC697CPU711 is widely used in legacy and expansion systems that rely on the Series 90-70 platform, supporting complex automation programs and large I/O configurations without requiring multi-slot processing hardware.

Hardware Parameters

This CPU module is built around an Intel 80C186 processor operating at 12 MHz, providing fast Boolean instruction execution and consistent scan performance. The single-slot VME C.1 format allows direct integration with standard Series 90-70 racks and associated option modules.

Key technical characteristics include:

• 80C186 microprocessor with 12 MHz clock frequency

• Boolean instruction execution time of approximately 0.4 microseconds

• Support for up to 2,048 discrete input and output points

• Capacity for up to 8,000 analog I/O words

• Expansion memory support up to 512 KB

• Single-slot VME C.1 compliant form factor

• RS-485 serial communication via 15-pin D-sub connector

• Compatible with IC697 discrete, analog, and intelligent option modules

The module is designed for electrical noise resistance and stable operation in multi-module PLC racks.

Industrial Applications

The IC697CPU711 is suited for medium to large-scale industrial control systems where centralized processing is required. It is commonly deployed in manufacturing automation, material handling systems, batch processing, and infrastructure control applications.

Typical use cases include coordinating multiple I/O racks, executing time-critical logic routines, and managing data exchange with communication and specialty modules. Its proven architecture makes it a dependable choice for maintaining and upgrading existing Series 90-70 installations.
