General Electric IC697CPX928 CPU Module

The GE IC697CPX928 is a flagship central processing unit designed for the Series 90-70 programmable logic controller family. This module utilizes a 96MHz 80486DX4 microprocessor to handle intensive industrial automation tasks. It delivers high-speed Boolean execution and supports complex 32-bit floating-point math operations. Consequently, this processor serves as a reliable core for large-scale distributed control systems and manufacturing environments.

Memory Architecture and Storage

This CPU module features a substantial memory buffer to accommodate large application programs. The 6MB of onboard RAM maintains data integrity via an integrated lithium battery during power losses. Additionally, 256KB of non-volatile flash memory stores essential system firmware and user logic safely. These memory resources allow the controller to manage thousands of registers and internal timers without performance degradation.

Extensive I/O Scalability

The IC697CPX928 manages expansive hardware configurations with ease. It supports up to 12,000 digital points and 8,000 analog points simultaneously. Users can expand the system by connecting various IC697 discrete, analog, and specialty modules. Furthermore, the unit integrates smoothly with Ethernet interfaces and high-speed coprocessors. This scalability makes the module ideal for complex plant-wide automation strategies.

Communication and Interface Options

The front panel provides three primary serial ports for diverse connectivity needs. One RS-232 port and two RS-485 ports facilitate communication with programming terminals and peripheral devices. Moreover, the hardware eliminates the need for physical jumpers or DIP switches. Engineers perform all configurations through software-based tools on Windows or MS-DOS platforms. Seven diagnostic LEDs provide real-time feedback on the operational status of the processor.
