IC660BBA103 How-to Troubleshoot & Test Genius Block I/O Tutorial GE Fanuc PLC Training

Introduction: GE Fanuc IC660BBA103 Troubleshooting Guide

This troubleshooting guide is a test of a GE Fancu IC660BBA103 Genius Block thermal couple input analog block. What you are going to do is test all the functions and features of this block.

Step 1: The Setup

First, the hand-held monitor which is the IC660HHM501.(see below)



You are going to make sure that the port works (see above) and it can communicate and program the block. Second, the Serial Port (see above) which is connected to the peripheral devices which is connected to a Genius Bus Controller. That part number is IC693BEM331. And that bus controller is an IC693CHS397 5-slot rack and is being powered by an IC693PWR330 High capacity power supply and the IC693CPU374 Processor.

Step 2: Setup in Proficy Machine Edition

For this test and illustrated here is Proficy Machine Edition. (see below)


All of you configurations in Proficy Machine Edition are the same as what is in the Genius Block. What you are trying to do is once you have configured everything in Proficy Machine Edition and put the CPU into Run Mode, the Genius Block will have matching information including the block number, and you should get an I/O Enabled light. This tells you that the serial port, coming through serial 1 and serial 2 and shield in and shield out, and going back and forth to the Genius Bus controller  is communicating and that this port is working fine. (see below)


The next thing you want to check is the inputs: Thermal couple 1 through 6. Now in this illustration there is a thermal couple (see below) with positive and negative leads for two different types of metals. It is a J-Couple and it creates a mili-volt type signal which can be read by the IC660BBA103.


So, following is the way to configure this block. You power up the hand-held monitor (see below) and you should normally keep all the blocks and your test equipment at 153.6K Standard.



You may have a different application which is fine. So you check that it matches what you’ve got. Select OK. Now select F3 Configuration, F1 Pro Block ID. And what you would normally do is F2 which changes the block number to 1 and Enter. And again, this is how you can get the LED light on because this information matches Proficy Machine Edition.

And now you go back to Home, F3 Configuration, F2 Configure Block and you illustrated here is having everything set to factory settings on the Genius Block but you may have different settings which is fine. But you do want to test every channel, so you have all these toggled for Yes. And the Thermal Couple you are using is type TC Type-J.

You may be using different settings for your purposes which is just fine. Ok, so you are going to go back to Home, and you want to analyze all 6 channels. F2, F1 to Monitor Block. You can monitor two channels at a time and then you have to move on.

You are now going to touch the leads to the thermal couple so you can see the reading. And since all of the channels are set to the same settings, all of your readings should be the same or close to it. So the first one you are going to go to thermal couple one, that is TC1 plus and minus. And you should have a reading of almost 35, touching terminals 13 and 14. And you go to thermal couple number 2, should have a reading of almost 34, very close to the same.

Now you are going to switch over to 3 and 4. I am touching terminals numbers 21 and 22 to get channel 3. Again, you should get very close to the same reading. Channel 4 is 33.1 while touching terminals 23 and 24. You are now going to toggle one more time F1, get to channels 5 and 6. Channel 5 using terminals 29 and 30 and channel 6 using terminals 31 and 32.

So all of the readings in this illustration are pretty much the same, which is good to see. They are all within one degree and that is good

Step 3: Additional Steps if Necessary

Now if you power up your Genius Block and you don’t get any lights on or if you using the hand-held monitor and you go to program the ID and you get a question mark and are unable to store or program any information that is able to be saved in the Genius Block and not responding you very likely have a troubled device. If that is the case with you, please see links to help, parts and service below.
