IC697CMM711 Troubleshooting Test GE Fanuc PLC Training Series 90-70 SNP

Introduction: GE Fanuc IC697CMM711 Troubleshooting Guide

This troubleshooting guide is a test of a GE Fanuc IC697CMM711 communications co-processor.

Step 1: The Setup

Just to give you an indication of these LED’s here (see above) first this is OK LED Port 1 if you’re using Port 1 or Port 2. That refers to the two ports: port 1 and 2 also indicated by this door card (see below).

The IC697CMM711 communications co-processor is in an IC697CHS750 five slot rack. From left to right illustrated is an IC697PWR711 power supply and an IC697CPX772 processor and the rest of the slots are empty as this is just a simple test on the CMM.
Now, you should normally have an OK light on pretty early with this particular module, if you don’t then there’s likely a problem with the CMM. If you don’t get the OK light see links below for further help.

Step 2: Configuring Proficy Machine Edition

First you’re going to go to Proficy Machine Edition and set up the configuration that matches what you see illustrated here with all these modules. Proficy is now set up to read RS232 port and that’s a configuration that you can do. And once that’s set on both port 1 and port 2 under interface, you want to go to Target > Online Commands > Clear and you want to clear Controller Fault Table and I/O Table and nothing else. And then you want to Download and Run that Configuration. 
When it asks you what you want to Download just Configuration and Logic, the top two selections. So once that’s done you have to open up a program called Test Comm so what you will do is you’ll hit the Online and Offline command which is the lightening bolt. And so that you can detach the computer from the processor go to File and hit Exit out of Proficy Machine Edition and you are going to open what we have here called Test Com.
And Test Com is for GE Fanuc PLC test and then on the bottom left hand side you are going to go to a CCM type protocol and what this does, this is kind of like pinging the Ethernet, but there’s a signal exchange between this software and the computer and the CMM. In order to get that signal over the CMM you are going to be using this shielded cable (see below) you are probably familiar with if you’re using this device.

Step 3: Running the Tests

Go ahead and plug the shielded cable into the computer and this is set up for port one RS232 and it’s going to go to the CMM. Once that’s properly connected you’re going to plug your other end into the computer and then you are going to hit that port with this information by clicking a button that says Try All and immediately you should have a response.
If that’s good then you are going to put the cable onto port number 2. Once that’s securely on there and you’re going to go ahead and hit Try All again and if that’s good go to the next step.

Step 4: Reload Configuration

Now power this system down and then go back in and reload the same configuration except where it comes to the protocol you want to switch Port 1 and Port 2 to read the RS485 which is the other side, the other port, and make sure that it can read that value as well.
If you do have any problem, if you try to attach a signal to this and it doesn’t respond then you do have a problem with the CMM.
