How To Troubleshoot GE Fanuc IC697CPU782

Introduction: GE Fanuc IC697CPU782 Troubleshooting Guide

This is a troubleshooting guide for a 90-70 processor, IC697CPU782, in an IC697CHS750 five slot rack which is empty. You’re just going to be testing the processor. The power supply is an IC697PWR711.

Step 1: Configure and Power Up

When you power up you’ll see the top LED is our OK LED which is solid green and that’s a good sign. If your processor has a blinking light or no light at all then you definitely have a problem with this processor and you won’t be able to continue with this test. We do repairs, have exchange programs, re-manufactured parts and new parts so if that’s something you are interested in contact us at pdfsupply.com.

Step 2: Configure Software for Run Mode

Now that you are connected and turned on you’re going to connect up to the processor. Before you do so, note that with respect to Rack 0 and Rack 1, Rack 0 should have a BEM713 in it in Slot #2 and Rack 1 should have a BEM711. Note, this is just want you to put in the software, they don’t actually have to be in the rack but without that information in there, the CPU won’t go into RUN mode which is your ultimate goal.

Step 3: Connect Up & Go Into Program Mode

Now you’re going to connect up to it and monitor how the port is working through the Proficy* Machine Edition GE software. Now that you are connected up you know the port is working.
Now, go ahead and put it into program mode. Go to Target on your top menu bar and sub-category Online Commands and in that category Clear. Window will pop up with the ability to clear memory. Here you want to click the Controller Fault Table and I/O Fault Table. You DON’T want to click anything else, you don’t want to click All Memory because you may lose something that you’re trying to keep.

Step 4: Download & Run

Once that’s done, you’re going to hit Download and Run which is the Download Information & Run Icon. The goal is to get it into Run Mode. Now, the first thing it’s going to ask you is what do you want to download to the controller. Choose just Hardware Configuration and Logic and click OK.
Note:

1. You’re not going to write anything to the flash memory and you’re not going to do any I/O force values, You’re testing the hardware configuration and logic only.
2. Once the build is complete, you’re going to have LED’s on if this is functioning properly. And you’ll be able to test the toggle switch.
3. When it’s in run mode your notice the following LEDs: the OK LED is top, the middle LED is RUN run enabled, and the bottom LED is the I/O Input Output enabled. (see image below)
4. Now test the 3 position toggle switch, and this is fully on. When you go down one you want to shut off the I/O the I/O Disabled and see that it works. The next one is to disable the Run mode and see if that works also.

Step 5: Test Memory Protect Using the Key

The next thing you want to do is test Memory Protect using the key on the top key barrel to see that your feature is working. So turn this on and it should indicate with a green LED that this feature is working.

Step 6: Additional Steps if Necessary

If you think that you’re having a problem with the processor, what we’d like you to do is leave the processor running overnight or over a weekend, or a couple days, maybe three days, and if the processor kicks itself out of run mode or falls out of run mode, you want to refer back to the Proficy* Machine Edition, go to Target and the sub-category Diagnostics.
Your info-viewer will show a fault table once you click on that and it will tell you exactly what the problem is, why it fell out of run mode and if you still can’t figure it out or if it’s giving you faults that you don’t understand, this is something that we look at and repair and you can contact us at www.pdfsupply.com .
