How-To Troubleshoot GE Fanuc PLC IC660BBD110 Genius Block Training Tutorial

Introduction: GE Fanuc IC660BBD110 Genius Block Troubleshooting Guide

This troubleshooting guide is a test of a GE Fanuc ICC660BBD110 Genius Block. This is a 16 point Input discreet block with 115 volt AC.

Step 1: The Equipment Setup

What you are going to do today is test the functions and features of the block. First one is the hand-held monitor. (see below)


This handheld monitor is part number IC660HHM501. You want to make sure that this monitor, or programmer if you will can communicate with the Genius Block.


The second thing is the Serial Port connection 1 & 2 (see above), shield in and out which is communicating back and forth with the Genius Bus Controller. That part is IC693BEM331 and it is connected to an IC693CHS397 5-Slot Rack, is being powered by an IC693PWR330 Power Supply and controlled by an IC693CPU374 Processor.

Step 2: Setting Up Proficy Machine Edition

You should be using Proficy Machine Edition as illustrated (see below) in this test and what you are going to do is in the Proficy Machine Edition to make sure that your configuration in the IC693BEM331 is the same that is what is represented in the Genius Block.


The reason you have an I/O Enabled light on (see below) is because that information has been stored to match what is in Proficy Machine Edition, and you are going use the IC660HHM501 Hand-held monitor to do that as detailed below.

IO Enabled LED On


In the handheld monitor you are going to go to F3 Configuration, F1 Program Block ID, F2 for Block Number, and you can always use number 1 for your test to keep it simple, and F3 for Enter.

The next thing you want to do is go back to Home, Configuration F3, F2 for Configure Block. In this illustration everything is set to factory standard settings. Now for your test purposes, you might NOT want to reset any of your settings. In fact, its recommended that you don’t if this is a Genius Block you have working in the field.

Another thing is that in this illustration the configuration protection is disabled so changes can be made if necessary. Again, if you have settings you need to keep, then leave this configuration protection enabled so nothing changes.

Now on the handheld monitor (see above) you are going to go back to Home, then F2 and F1 to Monitor Block. F2 is Analyze, F1 is Monitor Block. And you want to touch the lead probe to all of these and make sure the 0’s turn to 1’s.


What you should have is a 115 AC going to the hot and the neutral from that going to terminals 31 and 32. You can place a piece of electrical tape over terminals 31 and 32, this way you don’t inadvertently touch the hot lead to the neutral, you don’t want to do that.


Part of your test, you also have in terminal 13, a lead coming off. This is a hot probe. This has live power going through it, so if you do have this set up the way illustrated here but sure to exercise caution, because this probe is hot and it has 115 volts, and if you touch it it will shock you, so please keep that in mind.


OK, now you will be touching terminals 15 through 30 to turn on each input. And you will read your results in the hand-held monitor and you’ll see the 0’s change to 1’s and you can go through them pretty quickly.

For user interface, there are also LEDs to take note of that correspond with the touching of these probes to each channel. You do not want to go by just the lights. The lights coming on do not necessarily mean that the information is being carried over to the bus controller.

So do not go by the lights, please use the hand-held monitor to get an accurate reading, but note, the lights will come on. That is the feature of the product.

Step 3: Additional Steps if Necessary

So, if you power up your Genius Block and you do not get any lights on or you are using the hand-held monitor and the monitor is unable to store the program ID information and it leaves the question marks, or if your channels are not working then these are signs of problems with the Genius Block.
