How To Troubleshoot GE Fanuc IC697CPX935

Introduction: GE Fanuc IC697CPX935 Troubleshooting Guide

This is a troubleshooting guide for GE Fanuc 9070 processor, part number, IC697CPX935. You don’t have to worry about the revision letters, it is going to be the same test for all of them.

Step 1: Set Up For Test

Go ahead and put IC697CPX935 in the slot. The rack illustrated is an IC697CHS750 five slot rack, and the rack is empty since this is a test just for the processor with a IC697PWR711 power supply. Note, the door is removed so its easier to see.

Step 2: Connect Cable to Port 3

First thing to do is connect up to it using this cable this is an AS693232SNP, it has LED’s to show communication.

Plug that into Port 3 which is also the Port 3 LED at the bottom right hand corner. You’re looking for communication. The top LED, top left, is the OK LED.
 

If you are unable to connect or if you do not have an OK LED then there is obviously a problem with your processor and you will not be able to follow this test from here forward. This is something that we commonly repair, we also have exchange programs for new modules or re-manufactured. You guys can contact us at PDFsupply.com for more information.

Step 3: Getting Into Program Mode

Now that you’re connected up, first thing that you want to do is get into programmer mode. Note a Proficy* Machine Edition Software is used in this illustration.
You want to clear memory faults which in this particular case, I/O fault table and controller fault table. You do NOT want to clear the actual All Memory or Hardware Configuration and Logic because you don’t want to ruin anything that is on the processor.
Once that’s cleared, you’re going to click the Download and Run icon which is the download and information and run icon on the right, then it’s going to build a configuration of that in that empty slot rack power supply CPX. And when it asks you to download, you’re just downloading Hardware Configuration and Logic. That’s all you want to download. Not permanent flash memory, no initial force value so just Hardware and Logic.
Let this build.

Step 4:Getting the Processor Into Run Mode

Once it’s done building, you are going to get the processor into run mode. The processor has to be able to get into run mode in order to be a good processor, in order to be able to finish this test. And once you do get it into run mode, you are going to check the other ports and switches.
So, you’ve gotten it into run mode and you can see here these three LED’s  are green. The top is ok, the second or middle one is the RUN LED and the third is Input Output Enabled I/O Enabled. Once those are on, they are all functioning.

 

Step 5: Test the Toggle Switch & Memory Protect Switch

Note there’s a toggle switch that you can toggle through the following to.1) Shut off the I/O enabled, so it’s disabled. 2) To close off RUN mode. Checking if the green lights go off will determine if the switch is working.
The second switch, the Memory Protect switch which is located on the top and the LED that corresponds to it.

So go ahead and turn this on, it’s testing to make sure that your memory protection is enabled or able to be enabled.

 

Step 6: Checking Port 1 & Port 2

The last thing you want to check is the ports one through three.
You have determined that Port 3 is working so go ahead and unplug it and plug into Port #2. You should now see Port 2 blinking so you know its working.
The last port you want to plug into Port #1 and it’s a special cable, IC693CBL316. On one end it has what looks like a phone jack that plugs into the processor and the other side has a serial port connection and you’re going to plug into the computer.
What you’re looking for here is that this top LED is blinking and immediately it starts communicating so you know this is good too. So it’s still in Run mode.

Step 7: Additional Steps if Necessary

Now if you feel there’s still a problem let it run overnight over a weekend, or a couple days, and you want to make sure that it stays in Run mode. That is the goal: make sure that it stays in run mode.
If for any reason it fails and it falls out of run mode again, go to your Proficy Machine Edition in your top menu bar. In the middle there’s one category called Target. You want to click that and towards the bottom there’s a diagnostics screen and you can open up your diagnostic table  and your fault table. It will show you exactly why it fell out of run mode and maybe that will help you further.
