How To Troubleshoot GE Fanuc IC697CPX772
Hello and Welcome to PDFsupply.com
Today we are going to be testing a 90-70 processor. I have a part number here, IC697CPX772. do not be concerned about the revision letters, this test will be the same for all of them. It is just a simple test. I'm going to go ahead and put this in the rack. Power it up, what I'm going to do here is remove this door so that you can better see everything on the inside that I'm going to be pointing at. The first thing I want to do is plug in. I'm going to be using a cable here, AS693232SNP: this is a programming cable connected to the computer. It has LED's that flash when it's communicating and I'm placing that on Port 3. I'm going to go ahead and connect up. Now, it's communicating and it's connected up and if you are unable to connect then there's obviously a problem with the processor and this is something that we commonly repair here or we offer exchange programs and new units that we can ship very quickly, so please see our website www.PDFsupply.com. If you can't get connected you won't be able to follow this test.
The next thing is I'm going to place the processor into run mode and what I'm doing in the background is just going into a programming screen, clearing any processor or I/O faults. Do NOT clear any other information from your processor that you may need such as flash memory, just I/O faults and processor faults. Now, I'm going to go ahead and download and run. The processor is in an IC697CHS750 rack, the slots are empty because again this is just for the processor and it's being powered by an IC697PWR711 power supply. And again we can see this Port #3 talking these LED's are Port 3, Port 2 and Port 1 and I'll be going through that shortly. As soon as this build is complete, we'll be able to get it into run mode. So now, I have all three LED's on which means that the processor is in fact in run mode. The run mode is the middle LED the bottom is the I/O Inputs Outputs Enabled and I want to test this toggle switch below the LED's and that lets me shut off the I/O or put it back into run mode and all of those work. I also have, if you can see, a key on the top of the processor this is for memory protect, I'm going to turn that on and I should get an LED that comes on that tells me that my memory protect setting works, so that's fine. Now, last two tests I want to make sure that all the ports work, so I'm going to unplug Port 3, plug into Port #2 and immediately I have communication so I know that that works and I can see on my software screen that it's working so I'm going to unplug that and put it back. And last, I have a cable that fits to Port #1 this is IC693CBL316 it looks like a phone jack on one side and on the other side is a serial cable that plugs into my computer and as soon as I plug that in I should get some kid of response on the LED. Here and we do it's blinking and it's talking so this is good all three ports work all the switches work and the processor can go into run mode. That's the basic test, what I would recommend doing if you can get this far and you feel that the processor is a problem I'd leave it running over night or over a weekend a couple days and what you want to do is you want to make sure or check back that it's still in run mode. If for any reason it kicks itself out of run mode there's actually a problem with your processor you can go into your, I'm using Proficy* Machine Edition GE You can go into Target on your top menu bar into diagnostics and the diagnostics screen will tell you why it fell out of run mode.
I hope this video helped you.
