IC693ALG222 How-to Troubleshoot Test GE Fanuc PLC Proficy Machine Edition Programming Tutorial

Introduction: GE Fanuc IC693ALG221 Troubleshooting Guide

This troubleshooting guide is a test of a GE Fanuc IC693ALG222 high density analog voltage input. It measures voltage and is high density because you can select from one to 16 channels or more realistically. Either eight or sixteen channels. I am holding up the 16 channel door card and i will show you the other side.

Step 1: Check Configuration & Door Cards

This (above) has two different wiring schemes. The A channel has a different wiring scheme from the 16 channel, and that is something to note. It is important because depending on what you select in Proficy
Machine Edition is how many channels you are going to get and where you are going to get the information, ie: to what terminals, in order to get a reading for your program.

Step 2: Configure Proficy Machine Edition of the Test

What you are going to do is test this module and configure it in Proficy Machine Edition since this requires a bit more configuration than most of the other analogs.

Physical Setup & Proficy Configuration

What you have in front of you is an IC693CHS397 5-slot rack powered by an IC693PWR330 power supply and the processor is an IC693CPU374 plus. The system is already in Run Mode. You have put it in Run Mode and you download the information through Proficy Machine Edition. To do this open a new open file.

In the main rack select the same rack power supply, CPU and ALG222 as you see physically illustrated here. What you want to note is that under slot number 2, if you right click and select configure or double click on slot number 2, a tab will pop up next to your info viewer that has the settings and the configuration for this analog card.

Step 3: Testing the Channels

And this is something that you want to pay close attention too. Under perimeters it says active channels. How many channels do you want active. When you first start this system it is just going to say one. And what you want to do is go in there and change that to eight or sixteen, depending on how many channels you want to test. (see below)

It’s a good ideas to start by selecting eight channels (see above) to start with and test this first door scheme that you see illustrated here . . . all these channels and there corresponding terminals. And then when you are done with that test and that test is good, go ahead and test the 16 channel version.
Again, under active channels where it says values, you can either right click and use the data entry tool. An active channel window will pop up and you can select or you can just manually input next to the blinking cursor the number of channels you want.

Step 4: Checking Your Reference Address

The next thing is to check where your reference address is, where you are going to be seeing these readings. This is a new file, it is an empty file that you are using just to simply test the IC693ALG222 so your reference address will obviously start on percent A/I 0001 Analog input reference address 1.
And the next thing is that the other bit of information that is adjustable on the IC693ALG222: if you go to input channel data, which is the third tab underneath IC693ALG222. For each channel you can select the range of voltage. Go ahead and go with -10 to +10, the full scale range. But for your purpose, 0 to 10 might be sufficient.

Step 5: Selecting the Voltage for Each Channel

You want to select the voltage for each channel. (see below) Every channel has to have the same voltage, whether it is 0 to 10 or -10 to +10, so that when you probe these channels they all give
you the same reading, if they are working properly.

So that is the configuration of the IC693ALG222 and Proficy Machine Edition.

Step 6: Doing the Test

Next thing you want to do (see above) is select,under in the navigator bar, Reference View Tables, then go to Default Tables, and select Analog Input. You can double click on that or right click and click open. Once you have that open and your configuration is correct and you have downloaded it and the processor is in Run Mode, you are ready to do your test.
You are going to want to have the analog input table open in front of you.
You are going to use a 3-volt lithium battery (which is what PDF Supply uses). The positive and negative leads coming off. And this way you can probe each channel. Again, it is 3-volts and it is going to give you the same exact value for each channel, or it should if the channels are working properly.

So you are going to go ahead and test each channel. Again, check your door card for the wiring diagram.There are 8 channels all together. So if you are satisfied that all of the channels are working properly on the eight channel configuration repeat that same process on the 16-channel. And if all of these check out, then i am 100% sure that it is a working card.

Step 7: Additional Steps if Necessary

So others things you want check:

• is the OK light on?  The PS OK light on this is not necessarily a power supply but it is the voltage that is coming from the back plane. So if that is working, that light will be on if its a powered up module.
• if for any reason any of the channels are not working on either of the two door schemes, the 8 channel or the 16 channel or if the OK light is off and not working, those are all things we see with troubled modules. In this case there is something definitely wrong with the module.
