IC693BEM331 Proficy Machine Edition Training GE Fanuc PLC Bus Controller 90-30 & GENIUS Block

Introduction: GE Fanuc 90-30 Troubleshooting Guide – Testing a Genius Bus Controller

This troubleshooting guide is a test of a Genius bus controller, an IC693BEM331. There are two ways to test it and configure it in Proficy Machine Edition.
Illustrated is an IC693CHS397, 5-slot rack powered by an IC693PWR330 power supply and an IC693CPU374 plus processor. Also illustrated for this test is an IC660BBA020.
You don’t have to have this specific Genius block, but it is illustrated because it has both inputs and outputs and are needed for the illustration. Also illustrated is the IC660HHM501 handheld monitor.

Step 1: In Proficy Machine Edition Open New File and Select Main Rack

To begin go into Proficy Machine Edition for a moment. open up a brand new file and select a main rack. Switch to the CHS397, 5-slot rack, PWR330, and CPU374 plus. In slot number two is the BEM331.

You should see the same physical configuration in front of you that you’ve got in your Proficy Machine Edition software. You’ll do two configurations.

Step 2: Navigate to CPU Settings

First, with slot number 1, CPU374. If you double click on slot number one, the tab will pop open so that you can make adjustments to the settings of the CPU. Under settings and under subcategory parameters the fourth selection from the bottom is key switch run stop.

Key switch run stop activates so when the processor is in run mode and you turn it on, it goes into run mode, but you are able to shut it off from the processor.

Step 3: Configure BEM331

Now you should have that set as enabled. And the next thing you do is to double click on slot number two to configure your BEM331.

And under the device type, for this particular configuration, the way it is configured, the hand held monitor, the Genius block, is as a 4 analog input, 2 analog output serial bus address. Which is SBA number 1, just for simplicity sake.

Step 4: Test Genius Block Bus vs. Genius Block BBA020

So….the first thing you’re going to do to test this is to test the Genius block bus controller against the Genius block, BBA020.

Currently the block is powered up and it’s okay. There’s only one LED on. The I/O enabled circuit is not on right now. There’s a serial cable connection that’s terminated with a 150 ohm resistor. At the other end of that serial is the actual genius bus controller. If you look, screw 4 is going to serial 1 and screw 6 is going to serial 2, and again you have it terminated with a 150 ohm resistor and shielded. Your shield cable is on number sixteen. Your shield cable is shield in on the Genius block.

Step 5: First Test

In this illustration the Genius block has been configured using the handheld monitor as a serial bus address number 1 or block number 1. What you’re looking for is two things when you are using a Genius block for this test.
First thing is that when you turn the key into the on position, you should get an I/O enabled LED. This tells you that the Genius bus controller is actually communicating now with the genius block when you’ve turned this switch on.You should have an IO enabled LED on.

 
The second part of the test, more importantly, is whether the Genius block in your particular case is analog in and analog out. And the purpose for that is that when you touch the analog input with voltage, you should be able to see that voltage being read through the analog input, through your default analog input tables.
So that tells you that you’re able to put a power source here, 0 to 10 volts, and you are able to see that value go through the Genius bus controller to the Proficy Machine Edition. Then that verifies that that part is working.

 
The other thing you want to do is the analog output. You can do the reverse effect, meaning are you able to put a value in the analog output table and read it through the voltage out of the Genius Block itself.
And that way you’ll know it can communicate both ways. It can tell the Genius Block what to do and the Genius Block can send a signal through the genius bus controller, the BEM331, to Proficy Machine Edition. So that is the first way to test it and that is a pretty thorough and complete way to test it.

Step 6: Second Test

The second way to test it is using UMK-SE11,25-1 from Phoenix Contact.
You have the same serial connection as noted above on the BEM331 (see below). Illustrated are slightly different terminals, but still the use of serial one and serial two.

And then that’s connected through the Phoenix Contact. Which has a 9-pin connector (see below) that will go to the handheld monitor.

Step 7: Connecting the Handheld Monitor

Once the hand held monitor is connected, the hand held monitor should be able to read the same exact configuration address and the version, the firmware version of the Genius Bus controller through the handheld monitor.

Step 8: Use Handheld Monitor to Analyze

Now you should still be in run mode and you should have this communication light on, the okay light on. This shows you that this is a working unit. Now go ahead and turn your handheld monitor on. Select okay. And the next thing you want to do is select analyze, which is F2 and block bus status F3. (see below)

You’ll see: 1) bus address number 31 and 2) version 1.7, Series 90.
So that’s another way to test it to see that it is actually communicating. It’s showing you that is actually in the Genius block and in the handheld monitor and the Proficy Machine Edition configuration.

Step 9: Additional Steps if Necessary

So that completes the test. If all has worked you can be sure that this is a good working unit with either of these tests depending on what types of props you have in order to test, whether it’s a Genius block or this Phoenix Contact communication circuit that we have illstrated here.
Also, of course you can see that the okay light is on and the communication light is on.

There are a few things that you might see that are wrong right off the bat

• a unit that you plug in and power up and doesn’t show any lights on at all. You do not get an okay light. That’s a very quick and immediate observation that there’s something wrong with the module.
• if you have the processor in run mode and you don’t have a communication light. If the communication light is off, that could technically be a problem and of course if you do either of the two tests described, with the Genius Block or the handheld monitor, and it is not giving you any type of response that there is anything there and communicating, that’s another problem.
