IC693MDL240 How-to Test PLC Training GE Fanuc Proficy Programming Input Module

Introduction: GE Fanuc IC693MDL240 Troubleshooting Guide

This troubleshooting guide is a test of GE Fanuc IC693MDL240, a 16-point 120-volt AC input module so it’s a discrete input, 8 A channels, 8 B channels and it’s 120 volts AC.

Step 1: The Setup for the Test Procedure

Illustrated here, according to the wiring diagram, is a neutral connection from a 120-volt AC Wire connected to terminal number 19, as described here. The is a hot lead, or load 1, connected to a probe.
When you are ready to do the test you’re going to plug this in and you’ll be able to touch all the corresponding points, terminals 1 through 15, in order to initiate all these inputs.(see below)

 

Step 2: Physical Configuration & Setup of Proficy Machine Edition

The physical configuration that’s illustrated here is an IC693CHS397 5-slot rack, IC693PWR330 power supply and the processor is an IC693CPU374 plus.
In Proficy Machine Edition (see below) what you’re going to do is open a new blank file. You’re going to select the CHS397 5-slot rack, PWR330 power supply, CPU374-plus CPU and the MDL240 that you’re going to be testing.

The same configuration you are putting in your navigator bar under Main Rack is the same physical configuration that is illustrated here. Once you’ve done that you’re going to click the lightning
bolt icon in the upper left hand corner which is the toggle online/offline button. Once
that’s connected to the CPU you’re going to click on the hand print, which is toggle to online
mode, or put it into programmer mode.
Before you go any further what you want to do is take a look at your slot number 2. You can either double-click on slot number 2 where the end yield 240 resides or you can right-click on it and select Configuration.
You want to see, under Values and Parameters on the Settings tab, where the reference address is. In this particular file, illustrated here is % I00081. For your reference it may start with just 00001. Just make sure that you know where your reference address is, that you know where to look for the inputs being turned on and turned off as you probe them.
The next step is you’re going to go to Target, top of your screen, and go to Online Commands. Another screen will pop open; you want to go to Clear. When you get the Clear Memory screen up, you just want to make the bottom two selections which is Clear Fault Controller/Fault Table and I/O Fault Table. You don’t want to clear any memory in the CPU that you may want to keep or is important to you so, again, just the Controller/Fault Table and I/O Fault Table. Select okay.

Step 3: Select Download & Run

The next thing, of course, is to select Download and Run, which is the button that looks like downloading information with a green arrow going and a play button in the same button.
You’re going to get a screen that pops up that says Build in Progress and it’ll ask you what exactly you want to download to the controller. For our sake, for this test, we just want the top two selections, which is Hardware Configuration and Motion and Logic. We don’t want to write anything to permanent flash memory or any initial force values. This will be sufficient for our test. Select okay.
After this build is complete it’s going to ask you if you want to start the controller, Enable the Outputs to yes or okay. Now it’s in Run mode so what you can do at this point is go to your navigator bar, open up your default tables or expand your default tables, which is under Reference View Tables and double-click on Input or right click and open your input table. (see below)

 
Then you need to go to the corresponding bit, which are now only 0s but they’ll turn to 1 as you turn them on, and find out where yours begins. I have to start at 81 so I have to find out where that location is first. Once you have found it you’re going to go ahead and try and turn all these bits on by touching each terminal point with the corresponding channel.

 
Start with A1. For user reference, you can see that the LED under A1 is on and as you go through you’ll continue to see these LEDs go on. However, just because the LED is coming on doesn’t necessarily mean that the information of this input is being sent through the CPU to your program, so just make sure that you are able to see it on your reference view table as you go through and test all these.
Again, these numeral LEDs that come on are good for user reference but they don’t mean that everything is working perfectly.
In the input view table you’ll be able to see all the address locations turning on and off
as you proble each one. That’s exactly what you want to see. It’s a very simple module;
it’s on or off.

Step 4: Additional Steps if Necessary

A couple common problems that we see aqe:

• the light comes on when you probe it and you don’t get any information to your reference
  table or,
• when you touch it you don’t get a light on at all.
• Those are pretty much the only two problems that you’re going to see with this module. It’s a pretty simple module.
