IC697CPM790 is a GE FANUC manufactured 64 MHz CPU with calculation capability using a 32-bit floating point and microprocessor 80486DX2. This CPU utilizes single-slot programming software which works with Windows or MS-DOS to perform configuration and programming.
IC697CPM790 includes up to 12K discrete inputs and outputs (mix- simplex mode only). It has flash memory dedicated for OS firmware, allowing firmware updating through the connection between PC and module's serial port. The user controls module operation with programming software or via operation mode using the RUN/STOP three-position switch. A memory protection key or software password locks the configuration and program data.
IC697CPM790 has four green LEDs that indicate the status of the CPU. Fan assemblies are required for air cooling. The user can connect Bus transmitter module IC697BEM713 to the programmer for the parallel interface. A Type D connector with 15 pins connects the serial port, which is RS-485 compatible. During actual operation and power-up, the CPU verifies rack configuration while its alarm function reports any deviations in programmed and/or actual configuration. IC697CPM790 has a lithium battery that maintains calendar clock operation, data memory, and program memory.
It is important to note that module IC697CPM790 must be used alongside a Standalone C program, which provides Triple Modular Redundancy (TMR) operating and autotest routines. It will not operate unless this program is included in the loaded application program.
Supported option modules are as follows: IC697 LAN Interface modules, Programmable Coprocessor, Alphanumeric Display Coprocessor, Bus Controller for IC660/661 I/O products, communications modules, I/O Link Interface, and the IC697 family of discrete and analog I/O modules.
