IC693CPU313 Rack Troubleshooting Tutorial GE Fanuc PLC Intelligent Platform Proficy Training

Introduction: GE Fanuc IC693CPU313 Troubleshooting Guide

This troubleshooting guide is a test of a GE Fanuc IC693CPU313 on a five slot rack with embedded CPU, so it’s a CPU slot rack. And it’s being powered by an IC693PWR330 power supply. In this illustration you will be connected to a Proficy Machine Edition. Your goal here is to try and get the processor into run mode and have it remain in run mode.
So this is a test just to see the functionality and make sure that the processor is in good working order.

Step 1: Preparing for Test: Remove Any Modules

If you think you have a troubled CPU, remove any modules you have on it. You should test it on its own with a power supply. If you turn the power supply on and you have an okay light, that’s a good start.
However, if you don’t have an okay light….if the screen LED next to okay is not on, then immediately you have a problem with the processor’s self-diagnostic. There is a problem and you won’t be able to follow this test.

Step 2: Proceed with Configuration

If you have the okay light on and it’s powered up you can move on to the Proficy Machine Edition.
Now in Proficy Machine Edition what you’ll do is select a brand new file – a clean, open file which you’ll select under CPU. If you open up, in your navigator, under main rack, you can right click on CPU or double click on CPU and that allows you to change the module of the type of CPU. In this illustration we’ve chosen a CPU313 and a PWR330 just as you see, physically see it in front of you, and in this illustration. There are no other modules illustrated because this is just a test to make sure that the functionality of the CPU, on its own, is working and able to get into run mode.

Step 3: Connect to the Processor

So now that you have it powered up and you’re in Proficy Machine Edition (see above) the first thing you want to do is click on the lightning bolt icon which is the online/offline button to get connected to the processor. So you’re going to go ahead and do that.
Okay and then once you’ve got that on, a green handprint icon which is toggled to online mode or program mode, you’re going to click that. Alright.
Now that you’re in program mode, on your top menu bar under target – open that up. Click on online commands. Go to clear. And you want to clear controller fault table and IO fault table only.
Don’t do all memory and don’t do anything that would erase anything that you may need. So once you’ve selected the bottom two selections, again that’s controller fault table and IO fault table, go ahead and select okay and then click yes to clear those.

Now once that’s cleared you’re going to hit the download and start active target button. So it’s the icon to the far right that shows downloading information and a play button or a run button (see above). You’re going to click that. Now the first window that’s going to pop open is going to ask you exactly what you want to download to the controller. Just configuration and logic. Note, you don’t want to set any IO in motion or attempt to download any IO. You don’t want to put anything to permanent flash memory.

Step 4: Build in Progress

Again, this is just a test to turn the CPU to run mode and have it remain there. So you’re going to select okay to configuration and logic. And it’s going to tell you that there’s a build in progress. A window will pop open asking if you want to overwrite this as a new name. You want to select yes. And then the last frame that will pop open is going to ask you if you want to turn the outputs on, the IO on or put the controller into run mode. Outputs enabled – yes. Start controller.
Now you should be in run mode. You’ve got this green LED. (see below) So if you’ve gotten that far and you select run mode, you should get this green LED to come on once you start the controller.

Step 5: Additional Steps if Necessary

If the LED doesn’t come on, if you don’t go into Run Mode, then you need to read through your feedback zone which is in the bottom left hand corner and find out why it’s not in run mode.
You could have selected the wrong CPU or there could be a problem with the CPU.
First thing to do is to leave this in run mode for a couple of days, two or three days, just to see that it doesn’t kick itself out of run mode for some reason. If you come back after two or three days and it’s still in run mode, it’s likely a healthy processor. There’s probably nothing wrong with it.
If you come back and it’s not in run mode and it’s evident that it kicked itself out of run mode, what you want to do is go into Proficy Machine Edition again to target. And then three quarters of the way down, you’ll see diagnostics. And you click on that and in your info viewer tab, the main screen, a fault table viewer will pop open and it’ll give you the location and the description of the problem – the fault or error.
Sometimes information you see there is easy to understand and sometimes it’s technical information that’s difficult to understand without a manual. Sometimes it could be pretty obvious what the description is. It’s different every time.
