The GE Fanuc Emerson IC697CPM790 is a CPU that can be employed for the Series 90-70 of Programmable Logic Controller (PLCs). The IC697CPM790 offers a speed of 64 Megahertz and high calculation efficiency, employing an 80486DX2 microprocessor and a 32-bit floating-point. The IC697CPM790 is a single slot CPU that can be programmed and configured through either MS-DOS or Windows, over either SNP or Ethernet TCP/IP port. The IC697CPM790 includes four (4) green LED indicators to show the CPU status. The IC697CPM790 includes a battery-backed memory of one (1) megabyte and 512 kilobytes of memory that can be employed for a ladder diagram program. The IC697CPM790 offers 12-kilo discrete inputs and outputs and 8-kilo analog inputs and outputs. The IC697CPM790 provides 0.4 microseconds per boolean function and supports IC660, IC661, and IC697 I/O modules.

This CPU has configurable data and program memory which can be locked and protected using either software or key password. The IC697CPM790 can be controlled using either programming software or the RUN/STOP three-position switch. The IC697CPM790 includes a 15-pin type D serial connector which is RS-485 compatible. The IC697CPM790 contains a lithium battery with a shelf life of ten (10) years at 20 degrees Celsius (68 degrees Fahrenheit) to maintain data, program memory, and calendar clock operation. The IC697CPM790 requires a current of 3.3 Amperes at a voltage of 5 Volts DC. The IC697CPM790 includes flash memory to store and save CPU firmware and user data during the upgrading process between PC and the serial port. The unit weighs approximately 820 grams (1.8 pounds) while shipping and operates at zero (0) to 60 degrees Celsius (32 to 140 degrees Fahrenheit) for industrial applications.
