Introduction: GE Fanuc IC697CPM915 Troubleshooting Guide

This troubleshooting guide is a test of a GE Fanuc IC697CPM915 Central Processor. The door and door card have been taken off just so that they don’t distract from this illustration.

This guide will go over all of the information contained on the door card and some of the other features that this processor has.

Step 1: The Physical Set up

Illustrated here is an IC697CHS750 5 slot rack which is empty other than the processor and that’s because you are just trying to get this into Run Mode. Next is an IC697PWR711 power supply which you should have powered up and the first thing you want to take a look at is the OK LED and it should be solid.
So, if you don’t have an OK LED on or if it’s blinking, or you can’t connect, then there’s definitely a problem with your processor and you would need to stop immediately because you won’t be able to follow the test. That would be an indication that there’s a fatal error with the processor. If that’s the case please look at the links and information at the bottom of this page for help and supplies.

Step 2: Performing the Test

So, now that you are powered up you are going to go through a test. Note that the AS693232SNP cable (see below) has LED’s that are blinking and that’s good for user the interface so you know that the processor’s talking.

Step 3: Connected & Communicating thru Proficy Machine Edition

You should be connected and communicating with it through Proficy Machine Edition. Illustrated is a blank test file. So, now that you are connected you are going to go ahead and hit the hand print icon, the green hand print icon, which toggles to the program mode. Once it’s in program mode, you are going to go to Target on the top menu bar and down to Online Commands. Once you’re in Online Commands, you’re going to go to Clear and a window pops up and it asks you what do you want to clear.
Just select the bottom two selections which are Controller Fault Table and I/O Fault Table. Do NOT Clear anything else because you may end up clearing some memory or some information you need to keep on your processor and that could be dangerous. So, do not clear anything other than Controller and I/O Fault Tables.

Step 4: Download & Run

Now that you have done that you are going to go to the Download and Run button which is the Download Information & Run Icon in one button. Now the next window that pops up will ask you if you want to download to the controller and this is your goal. You want to get the processor into Run Mode and go through some of the switches and lights, that’s all. So, Configuration and Logic the top two selections, the Hardware Configuration and Logic, okay, so you are going to select that.
Once that’s done, it’s going to build what it is you have asked it to build and allow you to go into Run Mode and you are just about there.

Step 4: Checking LED Lights

Once you get into Run Mode you will see that three LED’s are on.

The Toggle Switch in the most upright position is the bottom LED and corresponds with the bottom LED telling you that the Outputs are Enabled and you’re in Run Mode. If you shut the Outputs off ie: Outputs are Disabled, then if you go to the bottom most selection for this Toggle Switch it shuts Run Mode off. 
Now the module is stopped. It’s manually stopped so you do this just to check that the switch is functioning and if it it appears that it is.

Step 5: Testing the Memory Protect Switch

The next thing is to check Memory Protect. There is a key that goes into the top Memory Protect at the top of the setup and it has a corresponding LED light.
When you turn it On you’re hoping to see that the LED is On. If the Memory Protect LED is not working it’s likely because perhaps the switch is broken, which does commonly happen. 
So, that’s just the basic features. There’s only one Port to test.

Step 6: Additional Steps If Necessary

Next is if you feel like this processor is a troubled processor and it’s giving you problems, you want to let it Run overnight or over a weekend, a couple days and what you’re trying to do is you’re hoping that the processor stays in Run Mode.
If you come in after a couple days and the processor is not in Run mode, then it kicked itself out voluntarily and there’s a reason for it. So, what you should normally do is go into Proficy Machine Edition, go to Target and go to Diagnostics and the Diagnostics Table will open up in your Info Viewer and it will let you know what happened and why.
Sometimes the information is hard to interpret because it’s all technical terms and codes but there are times that valuable information does come up.
