IC697PCM711 How-to Troubleshoot GE Fanuc PLC Training Series 90-70 PCM711Programmable Co-Processor

Introduction: GE Fanuc IC697PCM711 Troubleshooting Guide

This troubleshooting guide is a test of a GE Fanuc IC697PCM711 programmable co-processor. It’s in an IC697CHS750 5 slot rack with no other modules with an IC697CPX772 90-70 processor, although you can use pretty much any processor to do this test, and an IC697PWR711 power supply.

Step 1: Add module to Proficy Machine Addition

What you want to do is in Proficy Machine Edition add an IC697PCM711 in slot 2. In this illustration, a battery is not installed as its just a test that the modules work but if you have a battery on yours and you’re trying to keep a program or any information in there, please make sure that you keep your battery connected to this battery slot indicated in the image below.

Step 2: Configure Ports 1 & 2 with RS232

So what you should do now is configure it and on port 1 using an RS232 interface (see below) and on port 2 using an RS232 interface allowing you to use port 1 for the first part of the test to check that the two ports are working.

Step 3: Configure Proficy Machine Edition

What you want to do is In Proficy Machine Addition go to Target > Online Commands > Clear and you want to clear controller fault table and i/o fault table and the processor. This is because the processor may have previous information to clear out so you can make room for this test.
Next you want to click Download and Run. Once you’ve clicked download and run it’s going to ask how exactly do you want to download and it will just be physical configuration and logic the first two selections nothing else.
And you should have this is run mode already so what you are going to do is hit the lightening bolt icon, you are going to take yourself offline which is going to free up the serial port in the back of the computer and you are going to go to File > Exit and go to Exit Proficy Machine Edition and you are going to open up TestCom which you can find online, it’s a PLC communications tester it sends information and receives it back from the PCM or CMM whatever you have.

Now you are going to use the drop down menu on the left hand side and use the CCM protocol and you are going to connect up to the PCM using port 1 first using an IC693CBL305 cable with the connector (pictured above) and you are going to go to the back of the computer and plug into serial port and you are going to hit Try All. It’s kind of like pinging and its going to send the information, a query that has a reply back. Note that if it sends a query and it doesn’t send a reply back and it keeps trying to send and it doesn’t receive then you’ve got a problem with the co processor.

Step 4: Testing Port 2

Next you are going to test port number 2. Try All and then you should have a successful reply. Again, if you don’t have a response then there’s usually a problem. You should usually test both ports to see exactly where the problem is if there is a problem and if you don’t have any reply then you definitely have a problem with the co-processor.

Step 5: Configure Post 1 & Port 2 with RS485

Now the second part of the test is you are going to close out of test com go into Proficy machine edition, go into your configuration, and the interface you are going to choose for port 1 or port 2 will now be the RS485 (see below).

So on theIC693CBL305 you are now connected to the other side, port 2, using the RS485.
And you are going to do the same thing as before and start with port number 1 and you are going to hit Try All and you should have an immediate response and port number 2 Try All and you should have an immediate reply indicating these are working fine.
So that completes the test. So again if you have any failures with port 1 or 2 when you’re using interface RS485 then there’s a problem with the processor.
