IC660BBA026 How-To Test & Troubleshoot Genius Block & Proficy* Machine Edition – GE Fanuc PLC

Introduction: GE Fanuc IC660BBA026 Troubleshooting Guide

This troubleshooting guide is a test of a GE Fanuc Genius Block IC660BBA026. This is a current source analog input block. There are 6 inputs. And what you are going to do is test all of the inputs. You are going to test the Serial Connection to the peripheral devices that can control it. And the Monitor Port, and you will be using the monitor to test this device.

Step 1: The Setup

Illustrated here is the controlling rack, an IC693CHS397 5-Slot Rack, an IC693PWR330 Power Supply in that rack, an IC693CPU374 CPU and a very important IC693BEM331.

Step 2: Configuring Setup in Proficy Machine Edition

Now in Proficy Machine Edition (see below), what you will do, is in the BEM331 Configuration table under Global Data, Block #1 is a 6-Analog Input Module. Just for test procedures you can call it Block #1 to keep it simple. And you also configure the block to be Block #1. And you are going to do this using the following setup.(see Step 3 below)

Step 3: Setting Up Block #1

First thing, you are communicating at 153.6k Standard. All the blocks that are in the factory default positions are going to be in the 153.6k Standard, and you are going to OK that. It does a quick self test and it in this illustration it passed.
This handheld monitor (see above) is an IC660HHM501 handheld monitor, Genius Product. So you are going to go to Configuration F3 and F1 Program Block ID, this is the first step. And what you will do is you will select Block F2 #1, and then F3 for Enter. When you do this you will have gotten Block #1. And that is the reason why you should have an I/O Enabled LED on right now, (see below) because this Block is configured the same as the program in Proficy Machine Edition.
IOEnabled LED
And it is in Run Mode. If you were to turn the Run Mode off, the I/O Enable would turn off. That is important because this is telling you that this is communicating with Proficy Machine Edition with the other peripheral devices just mentioned, so you know that this is working.

Step 4: More on How the Handheld Monitor is Configured

Ok, so now you are going to go to Home, F3 for Configuration, F2 for Block Configuration. You always want to stick with the factory default positions. So if you have taken this block you want to test it because you think there maybe a problem it’s not recommended that you change any of your configuration because this illustration is just showing you how this particular example for this test is configured.
Again, if you have a working device that your just questioning because you are not sure of it, do not change your configuration to match what is illustrated here.
Next is Channel active, Yes. Because you want to check all channels. and then there is a scaling. These are set to the factory settings. In this illustration you are going to go to Next, 400 milliseconds. 0 to 25,000 thousand for the low and high alarm. Again, factory standards. BSM present, no. Configuration disabled. Configuration protection you may want to keep yours on.
If you have it on do not change it; in this illustration it is disabled, so if you need to make changes you can.

Step 5: Analyzing the Block

So this brings us to analyzing the block. You are going to go to F2 Analyze. And you are going to go to F1 Monitor Block. And what you are going to get is these values, input 1 and input 2, that are currently zero. What you want to do is you want to probe the “In” and “Common” of each channel. 1, 2, 3, 4, 4, 5, 6 in “In” and “Common”.
And what you will get is the corresponding terminals that you are touching. And your goal is to see the values change, and if all the scaling is the same, then all of your values should be the same through all 6 channels.

Step 6: Testing Using the Milliamp Generator

So what you should have for this test is a 4 to 20 milliamp output generator, if you will. And this is going to generate the type of activity, the milliamp activity, that this block would see in the field. So you are looking for the proper readings.
So if you watch on your screen, and you are going to be touching terminals. 11 and 12, and getting a value of around 12.015. Again you are touching terminals 11 and 12 for Input 1. Input 2, you are going to be touching terminals 15 and 16. Again, your value should be very very close to the same. the major value is 12.
Now to get to 3 and 4, you aregoing to hit F1, toggle over to 3 and 4. You should be touching terminals 18 and 19. Again, your major value, if you can keep the device steady, is 12. Moving on to number 4, you should be touching terminals 22 and 23. Again, if the major value is 12, that is good.
You are going to go ahead and do 5 and 6 now. So for Input #5, you are using terminals 26 and 27. For Input #6, you are using terminals 30 and 31, with the major value of 12.
This also incidentally is powered up with a 24-volt DC. You should have a 24-volt DC Power Supply that
you can use for this test. It is plugged in here and you should see LED lights are on because it is working properly.
If you were able to use the monitor successfully and read values you know that the Serial Port is working and you know that the I/O Enable is working. You also know that all of the channels are reading the proper values, Inputs 1 through 6 which is pretty much the most the important part of the test. So this pretty much concludes your test.

Step 7: Additional Steps if Necessary

Now if you are troubleshooting and you think there might be a problem with the block, first thing is, when you do power it up with the 24-volt DC Power Supply, and you do not have any lights, then there is definitely a problem with the block.
But if you do have lights on and you go to your inputs and your inputs are not able to give you a proper reading, again, this is something commonly encountered.
Finally, another problem is when you go through the configuration information, and you select block #1. If the block does not allow you to save what you selected, then there is a problem with the block.
If you have any of these problems, please see links to help, parts and service below.
