IC693CMM311 How-to Troubleshoot Communications Module GE Fanuc PLC Proficy GE IP Support

Introduction: GE Fanuc IC693CMM311 Troubleshooting Guide

This troubleshooting guide is a test of GE Fanuc IC693CMM311 communications co-processor. You’re going to test the module and do some troubleshooting if necessary and configure in the Proficy Machine Edition software.

Step #1: Power Up Module & Place Into Run Mode

In this illustration is an IC693CHS397, 5-slot rack powered by an IC693PWR330 power supply. And the processor is an IC693CPU374. Place the processor in run mode using the Proficy Machine Edition and opening up a new, clean, fresh file and selecting the CHS397, 5-slot rack, PWR330CPU374 and the test model IC693CMM311 module in slot number two. The configuration illustrated is also set up in the Proficy Machine Edition under main rack.

Step #2: Configurations for Test

So the first thing you want to do is….on slot number two there is no real configuration, but you can open up by right clicking on slot two and select open or double clicking. Your parameters under configuration mode should be CCM only for this test.

Step #3: Setting Up Cable for Test

See port number two above. It’s a twenty five pin connector that goes to an IC693CBL305 cable which you will be using for this test. It’s a short cable approximately a foot long.

Step 4: RS232 port & RS485 port

Now under port number 2 on Proficy Machine Edition under interface you’re allowed to select a new value. If you right click under values, the standard setting is RS232 port. If you double click on that a window will pop open that will allow you to change to RS485 if you wish to connect with an RS485 port.

Step 5: Run Tests for RS232 and RS485

So for this test you’re going to use the standard default setting which is RS232 and when you’re testing this of course you want to test both ports unless you’re only using one port RS232 and you’re securely using that only. It’s recommended that you test both RS232 and RS485 to make sure that you have a perfectly working device.
So now that you have this in run mode you’re going to click the lightning bolt icon on the far left. Which is the online/offline button. Then you’re going to disconnect from the processor allowing the serial port on your computer to be used for something else…for a test com.
Then you’re going to exit out of Proficy Machine Edition and open up your test com software. The Test com software is going to send up a packet of information to this. You’re going to see if any information is received back to see that this port is live and active. It’s similar to pinging an Ethernet device.

 

Step 6: Select CCM Protocol

Now that you’re in your tests com you’re going to select CCM protocol on the left hand side of the test com screen. There’s a drop down menu underneath the com one serial. It says it should be starting with SMP protocol, but you’re going to use CCM for this.
The next thing you have to do is connect your CBL305 mentioned above. Note: the IC693CBL305 comes with IC693CMM311 as standard with new and re-manufactured products. The other end of the cable is plugged into the serial port

Step 7: Click Try All

The next thing you do is click try all and it’s going to send what’s called a query and then there will be a reply. So it should be query which sends out a signal and then a reply back from the CMM to test if it is actually working.

Step 8: Additional Steps if Necessary if Failed Test

If it’s not working what will happen is you’ll connect up, your light will be on and everything will be in run mode and you’ll hit start or try all and when it sends the information nothing comes back.

It it is not working it will continue to send queries until something comes back but in this case you won’t actually get a response if there’s anything wrong with CMM311. And that’s how you know that your communication port is bad. Sometimes you’re able to hit the reset button and that may help you out a little bit. Usually not though.
Another thing is if you plug the module in and right off the bat you don’t have an okay light….if it is blank, there’s usually something wrong with it.
