How To Troubleshoot GE Fanuc IC697CGR772

Hello and Welcome to PDFsupply.com

Today we're going to be testing a 90-70 central processor. I have here a IC697CGR772. You don't have to worry about the revision letters, this test will be the same for all of them. I've removed the door so you can better see everything I am going to be pointing out. This is the door, this information is on our website if you need it. I will explain what all of the different LED's, switches, and ports mean. So now that it's in our rack, which is an IC697CHS750, I'm going to power it up using a IC697PWR711 Power Supply. This LED that's blinking top left is the OK. The CPU OK port is not on, or if it's only blinking and you do not get a solid light, then there's obviously an immediate problem with your processor. This is something that we typically look at here at PDFsupply and we can repair. We also offer new units, re-manufactured units, and we can ship same day. So, if that's something that you need, please see our website at www.PDFsupply.com .

So now that it's powered up, I'm going to connect up to it using this cable on Port 3, this is an AS693SNP232 cable. I'm going to go ahead and plug that in and we are going to be looking for the bottom right hand LED to be blinking. And this incidentally will test Port #3 as well. We can see that it's blinking so we know it's working, and also we know it's communicating and talking. And now that that's connected we're going to go to target > online commands and we're going to clear controller fault and I/O fault table, bottom two selections in the clear memory category. We're going to hit OK you do NOT want to hit ALL MEMORY or any of your saved information, just those two faults in case there are any. What I'm doing in the background here using Proficy* Machine Edition GE software to control this processor. Now that I've done that, I'm going to hit the Download and Run icon which is the download information and run button in one icon and what we're going to download is the Configuration and Logic. We are not going to write anything to our flash memory or initial force values again, this is just a simple test. Our goal here is to get the processor here into run mode.
As soon as this is done building we should be able to do that and I can point out some of the other LED's and features and switches. Okay, so that was successful. Now, if you look up to right hand corner of the processor the first light again is the OK light, processor OK. Second light, middle light left side, is the Run Enabled And the third LED in the bottom left, is the I/O enabled. Input Output Enabled. And those are also controlled by this switch which we want to test right here. So, first setting is all the way up right now, first setting would be middle which is I/O disabled and then down one more, this is a 3 part switch, this is run disabled so now we have run enabled this which works fine. Next switch we want to test is our memory protect switch which is located on the top of your processor and when I turn this I'm looking for this LED to turn on and this tells me that the memory protect feature is working. And that's good. The last thing we want to do is test the three ports, we know Port 3 is working so we're going to go ahead and unplug this and go to Port 2. And we have communication so I'm confident that is working. And the last step is we have a special cable to plug into Port #1 this cable here is the IC693CBL316 has what appears to be like a phone jack on one side and the other side you can't see has a serial port connection to go into my computer. Plug that in, and then I'm going to plug in the computer side and we want to see the top right LED blinking and it says Port 1 is communicating, and it is. So we know that this is working properly so these are all the features and functions about this processor and it's in run mode so what you want to do at this point if you feel that this processor is a problem you can leave it running over night or over a weekend, a couple days maybe a few days, and you hope to find that the processor stays in run mode, that usually indicates to us that it's okay. If it falls out of run mode what you want to do, using your Proficy* Machine Edition (software) go to the top menu bar you can go to Target > Diagnostics towards the bottom of that selection. Then, your diagnostics table will open up and you can see why your processor fell out of run mode and it can probably better help you.

If that still doesn't work, again we offer repair services and you can reach us at www.pdfsupply.com with all the information.

I hope this helps.

Thank You.
