Description

GE  IC697CPU731  90-70 Series CPU Module

• Hardware Configuration: It features a 12MHz processor as the core and 32KB of CMOS memory. It is equipped with a lithium battery (IC697ACC701) for maintaining data, program memory, and the calendar clock.
• Communication Interfaces: It supports programming and configuration via Ethernet TCP/IP or SNP ports, and communicates with intelligent option modules and I/O using the standard VME C.1 format.
• Functional Features:
  • Capable of controlling processes, machines, and systems for real-time material processing.
  • Supports up to 8k analog I/O modules, including discrete and analog module series.
  • Users can control module operations through a three-position operating mode switch or programming software, with three green LEDs indicating the CPU status.
  • Performs configuration verification during power-up and operation, and has an alarm function to report deviations between actual and programmed configurations.
• Operating System Support: Compatible with MS-DOS or Windows operating systems, facilitating user operations and configurations using programming software under these systems.
• Working Principle: It cooperates with other modules in the series to transmit data via the bus. During the scanning process, it collects input data, performs arithmetic processing according to the program, and then outputs the results to the corresponding I/O modules. Its internal processor executes logical operations, numerical calculations, and other operations on various signals in accordance with program instructions to realize control over industrial processes.
