Product Description

The IC697CPX935 is a Single-Slot PLC CPU with three built-in serial ports manufactured by GE Automation and Controls.
It is capable of performing real-time control of systems. Using VMEC.1 format, the IC697CPX935 can communicate with different “smart option” modules via a backplane mounted on the rack. This device is operated via a three-position run/stop control switch or by a connection to a computer running appropriate software.


A 96MHz microprocessor allows this device to perform floating point calculations every 0.4 microseconds. Any mixture of 12K I/O and up to 8K analog I/O is supported by this device. The IC697CPX935 supports the following modules: the entirety of the IC697 family of discrete and analog I/O modules, programmable and alphanumeric display coprocessors, IC660 and IC661 bus controller modules, link and LAN interface modules, and communication modules.


One megabyte of on-board RAM memory is supported, which is maintained by a IC697ACC701 battery. Flash memory (NVRAM) is also supported with up to 256 kilobytes available for user data. System firmware is stored in flash memory. Disassembling the device or replacing the EPROM is not necessary for updating the firmware.


The IC697CPX935 is configured via a connected computer running MS-DOS or software applications in Win 95 or Win NT. Connection to this programmer computer is possible via a serial, parallel, or Ethernet interface. No Dual Inline Package (DIP) switches or jumpers are necessary. Operational settings are secured by a software password on the programming computer or a memory protect switch on the device itself.


To maintain a safe operational temperature in environments greater than 50 Celsius or 122 Fahrenheit, this device will require installation of a cooling fan with a minimum capability of 70 cubic feet per minute.


Refer to the product manual for proper installation instructions. Power to the rack should be off. Place the operational control switch in the stop position. The memory protect switch should also be off. The lithium battery may be inserted into either connector. Connect the IC697CPX935 to the rack. Restore rack power.

Series 9070 Bulk Memory


The Bulk Memory Area (BMA) is a contiguous block of memory (up to 4MB) that can be used by logic programs and external devices. BMA is available in the CPX processors, IC697CPX772, IC697CPX782, IC697CPX928 and IC697CPX935 (release 7.80 and later). Before BMA can be used, its size must be set to a value greater than zero in the Settings tab for the CPX processor configuration.


Use SVCREQ function 36 to read from the BMA to a local buffer area in the PLC, write from the local buffer area to the BMA, and retrieve the address of the BMA in the PLC. The only check done by the PLC is verifying that the specified local buffer does not fall outside the minimum and maximum available addresses for the application. The application must provide a valid local buffer area. Otherwise, unexpected results can occur.

Parameter Block Setup

This service request uses an input parameter block that consists of 11 words. The parameter block format determines how the local buffer is specified and is selected by the MSB in the Operation word. The format can be Segment/Offset (MSB cleared) or Address (MSB set).

Service Request Execution

If a requested operation in Service Request 36 fails, the function block will not pass power flow. If the BMA is not configured or if the parameter block contains invalid parameters, a read or write operation will fail. Only invalid input parameters will cause the Get BMA Size operation to fail, in which case the function block will not pass power flow. If a read or write operation is requested and the BMA is unconfigured (that is, has a size of 0 in the PLC), the PLC will log an informational fault.

  • Question:  When testing IC697CPX935, what should I do?  Answer:  You want to, first, plug it in. Then, make sure it is connected and communicating. 
  • Question:  If it is connected and communicating, what should I do next?  Answer:  You should place the processor into run mode and clear ONLY I/O faults and processor faults. After, click download and run.
  • Question:  If all 3 LEDs are on, what does that mean?  Answer:  It means the processor is, in fact, in run mode.
  • Question:  What do the LEDs stand for?  Answer:  The first LED is the processor, the middle LED is the run mode, and the bottom LED is the I/O enabled.
  • Question:  What do I do with the toggle switch (that is below the LEDs)?  Answer:  This toggle switch can shut off the I/O or put it back into run mode and you should test it to make sure it works.
  • Question:  What does the key at the top of the processor do?  Answer:  This key is for memory protection. When you turn it on, a LED should come on to let you know your memory protection setting works. 
  • Question:  Are there any other tests I should perform?  Answer:  You should test all the ports to make sure they work. A LED should light up to let you know it is communicating/working. 
  • Question:  If I think there is a problem with my IC697CPX935- What should I do?  Answer:  If you think there is a problem, you should leave it running over night or over a weekend and make sure it stays in run mode. 
  • Question:  If my IC697CPX935 won't stay in run mode- What is my next step?  Answer:  Your IC697CPX935 might need repair
