IC693CPU311 GE Intelligent Platform Support CPU Baseplate Tutorial Series 90-30 How-to Troubleshoot

Introduction: GE Fanuc 90-30 Troubleshooting Guide

This troubleshooting guide is a test of the 90-30 central processor, part number IC693CPU311.
Illustrated is a 5-slot rack with an embedded CPU. All you need is the IC693CPU311 and a power supply. In this illustration is an IC693PWR330 high capacity power supply, connected using an AS693232SNP serial cable connected to port one on the computer.

Step 1: Power Up & Check CPU that CPU light is On

So the first thing that you’re going to do to check the CPU is power it up and check for an okay light.
If you don’t have an okay light from the start then you’re going to have a problem with this test. You won’t’ be able to follow this test because there’s….from the start there’s a problem with your CPU.

Step 2: Open Proficy Machine Edition

Illustrated is a Proficy Machine Edition. You connect up to it using the lightning bolt icon….or the online/offline button. Then to the right of that is the toggle to online mode. It’s the green handprint. Which will appear once you are connected. When you click the green handprint, you’ll be in programmer mode

 

Step 3: Go Into Programmer Mode & Configure

At the bottom right hand side of your screen, you will see the indication that you are in programmer mode. Note that the the processor is stopped and disabled right now and the IO is disabled. Configuration is not equal and logic is not equal.

So what you’re going to do first is go to target and in then the drop down menu, go to online command and another window will appear. You want to go to clear and you’re going to clear the controller fault table and IO fault table – the bottom two selections.
You DON”T want to clear all memory or anything else you may have stored in the CPU. This is just a test to make sure that your goal, which is to get the processor into run mode, can be done and sustained without it failing. Now you’re going to select okay.
Next you’re going to hit the download and start active target or download and run button. It’s the icon that looks like downloading information and a play button in one.
Next, it’s going to ask you: what do we want to download to the controller? In this particular case, it’s just a simple test so you’ll download the hardware configuration and motion….and logic. You don’t need to have any initial force values and you don’t want to write anything to all flash memory.
Note that this is an illustration of a new, fresh, blank file featuring the CPU311 and the power supply mentioned earlier. The same physical configuration that you see here is what exists in the Proficy Machine Edition under main rack.

Step 4: Go Into Run Mode

Now that it’s downloaded, you will select to put it into run mode or enable the outputs. When you do you should see from the LED that you’re in run mode. The Proficy Machine Edition will also show that you’re in programmer mode. Run is enabled. Configuration is equal and logic is equal. So everything matches in the software, what it sees or what is happening physically here through the port.

Step 5: Additional Steps if Necessary

So that doesn’t completely conclude the test.
If this is a processor that you think potentially has a problem with, what you would normally do is let this processor run overnight for a couple of days, maybe over a weekend, or two or three days, to make sure that it’s able to sustain itself in run mode and that it doesn’t fail or fall out of run mode for some reason.
In the event that you are able to keep it in run mode for that length of time, a couple two or three days, then you can be confident you have a good functioning working processor.
If for some reason it fails and it falls out of run mode, there’s a couple things you can do. It usually means that it’s a problem with the processor. So now go to target, go to the drop down menu. Towards the bottom is diagnostics and in your info-viewer a fault table viewer will pop up and it will describe any faults or errors that the processor had and the reason that it fell out of run mode.
Sometimes these are understandable problems the way that the fault is described. Sometimes it’s not. It could be some technical information that would only help if you had a manual to describe what default means.
So at any rate, if you do have a problem with your processor, this is something that we do repair here at PDF Supply. We offer remanufactured products and new and same day shipping.
