Product Description

The IC697CPU781 is a Programmable Logic Controller CPU that fits into a single rack slot.
To communicate with various “smart option” modules, a rack-mounted backplane with several connectors is used. A toggle control switch with three positions or a connected computer with specific software is used to operate this device.


The IC697CPU781 has a 16MHz microprocessor. Boolean functions are calculated every 0.4 microseconds. Up to 8K analog I/O is supported by this device, along with any mixture of 12K inputs and outputs. Several “smart option” modules are supported such as the IC697 series of discrete and analog modules. IC697 LAN modules and bus controllers for IC660 and IC661 modules are also supported.


To store user and configuration information, an expansion board is required. This board supplies up to 512 kilobytes of volatile memory sustained by a CMOS battery and up to 256 kilobytes of non-volatile flash memory (NVRAM). The calendar and clock for this device is also sustained by the CMOS battery.


The IC697CPU781 is programmed with software on a connected computer, not DIP switches or jumpers. Special programs running on certain operating systems such as MS-DOS, Windows 95, and Windows NT are used to program this device. A parallel, serial connection to this attached computer is possible, as is an Ethernet connection. An Ethernet connection will require an Ethernet controller or type 2 Ethernet interface to be installed. Options to protect configuration data and settings include a memory protection switch or a password in the programming software.

Follow the device documentation while attempting installation. Do not attempt installation while rack is powered on. Place the device control switch into the stop position. Turn the memory protection switch to the off position. Connect the memory expansion board to the device. Install the CMOS battery into the appropriate slot on the device. Insert the device into the first available rack slot. Turn the power back on.

Customer Questions and Answers

  • Question:  What is an IC697CPU781?  Answer:  The IC697CPU781 is a 16 MHz, 32-Bit, Expandable Central Processing Unit from the GE Fanuc 90-70 Series.
  • Question:  What will I need to test my IC697CPU781?   Answer:  You will need your IC697CPU781, a slot rack, and a power supply.
  • Question:  If the top LED is not on or is blinking when I test my processor- What does that mean?   Answer:  It means you definitely have something wrong with your processor.
  • Question:  How do I test the port that is on IC697CPU781?   Answer:  Go into Proficy Machine Edition, clear the controller fault table and/or the I/O fault table- nothing else. Then, click download and run. You want to download hardware, configuration, and logic. The only thing you are trying to do is get the processor into run mode.
  • Question:  What does each LED indicate?   Answer:  The top LED is the OK LED, the middle LED is the run enabled LED, and the bottom LED is the I/O enabled LED. 
  • Question:  What else should I test on IC697CPU781?   Answer:  You should test the toggle switch (that is under the LEDs). This toggle switch turns off the LEDs and you should simply make sure it works by flipping it on and off. 
  • Question:  What if I think there is a problem with my processor?   Answer:  You should leave it in run mode over night or over a weekend to check and see if it will stay in run mode. 
  • Question:  What if my IC697CPU781 won't stay in run mode?   Answer:  Then your IC697CPU781 may need to be repaired
