How To Troubleshoot GE Fanuc 9070 Processor, Part IC697CPX782

Introduction: GE Fanuc IC697CPX782 Troubleshooting Guide

This troubleshooting guide is a simple test of the 9070 processor, part number IC697CPX782.

Step 1: Power Up, Connect Cable & Verify Port Light Blinking

Go ahead and power it up: The processor is in an IC697CHS750 rack, it is a five slot rack, it is empty, and it is being powered by a IC697PWR711 power supply.

Connect using a AS693232SNP cable (see image below) which has LEDs that will blink showing the communication. If you’ve plugged into Port 3, for example, you’ll be looking at the Port 3 LED blinking to make sure that it is working.

If you are unable to connect then there is a problem with your processor (CPX782) and this is something that is commonly repaired at PDF Supply or provided via the exchange program that ships used parts, new parts, and re-manufactured parts quickly to you.

Step 2: Clear Controller & I/O Faults, Download & Run Processor

Next clear any controller faults or I/O faults. You do NOT want to clear any other information from your processor, you do NOT want to clear all memory or any hardware configuration, logic, or anything like that. Just controller logic and I/O fault. Once you’ve done check to make sure that the slots are empty.

Next, go ahead and download and run. Only download your hardware configuration and logic, nothing else, nothing to the permanent flash memory. Use your Proficy* Machine Edition GE Software in the background here and once this build is completed, it will allow you to get the processor into run mode.

Step 3: Check LED Lights

Note the LED lights in the image below. The first one (on top) is processor, second one is RUN or RUN mode and the third is I/O enabled or Inputs Outputs enabled.

There’s also a toggle switch that you can use right below the LED’s to turn on and off so you want to make sure that that’s working. Second, test the memory protect switch to make sure it works. Now that you’ve turned that to the ON position see that you have a solid memory protect switch. (second image below).

Step 4: Check To See if Communication Ports are Communicating

Next is to check the 2 ports to see that they are communicating. If you used Port 3 try plugging into Port 2, that’ll be the middle LED on the right side. You’ll see that it’s blinking and communicating so you’ll now Port 2 is good too.

Step 5: Check To See If Cable IC693CBL316 is Communicating in Port 1

Lastly, check cable IC693CBL316. It looks like a phone jack on one side and on the other side is a serial connection that’s going to go to your computer. So, go ahead and plug that in on the back of the computer; you should have communication out of Port #1 blinking LED.

Step 6: Now that the Test is Complete, is your Processor Still Falling Out of Run Mode?

That’s a complete test! If you still feel like the processor may not working correctly you might want to leave it running overnight or over a weekend. What you’re trying to do is make sure the processor stays in run mode over a few days on its own.

If it doesn’t, then go back into your Proficy Machine Edition, go to the top menu bar target, hit the drop down and then there’s Diagnostic. Open the diagnostics table and it should tell you what happened and why it fell out of run mode.

If you still can’t figure it out, this is something that we commonly look at.
