How-to Troubleshoot IC697CPM790 GE Fanuc PLC Programming & Proficy Software 90-70 CPU

Introduction: GE Fanuc IC697CPM790  Troubleshooting Guide

This troubleshooting guide is a test of a GE Fanuc IC697CPM790.

Step 1: The Setup

The IC697CPM790 should be powered up. Note in this setup there is, to the right, a BEM713 (image 1 below) and there is an extended rack to the right, powered up. with a BEM711. (image 2 below)
Illustrated here is an IC697CHS750 5 Slot Rack and a BEM711CPM790, being powered by an IC697PWR711. The same rack and power supply is to the right and it has a BEM711 with extension cable. (see image 3 below)
This setup is going to be required for the IC697CPM790 in order to get this processor into Run Mode which is your ultimate goal.

Step 2: Power Up & Check OK LED

Note that in this illustration the door is off to the CPM790 just so that you can see more clearly.
So, first thing to do is power up and you should have an OK LED light and as usual, if you don’t have an OK light or your OK light is blinking and you don’t have communication, that means that there’s a problem with your processor and you won’t be able to follow this test. If that’s the case, please see the bottom of this page for links to parts and service.

Step 3: Connect Up to Processor Using AS693232SNP

Okay, so now that you do have it powered up, you want to connect up to it using an AS693232SNP serial cable (see image below) and open up Proficy Machine Edition.

Step 4: Configuring for Build

What you are going to do is go ahead and connect up to the controller using the lightening bolt icon connector and using the hand print and you are going to go Online into program mode.
Alright, now that you’re there the next thing you are going to do is you’re going to go to Target, go to Online Commands. In the Online Commands window you’re going to go to Clear and what you’re going to Clear here is the Controller & I/O Fault Table it’s just the bottom two selections.
Don’t click on anything else you don’t want to clear or any information that you may need, that could be dangerous, so again just the Controller and I/O Fault Table. So once that’s selected, go ahead and Clear that and you’re going to hit Download and Run which is the Download Information & Run button icon.
Okay so as you are doing that it will ask you what you want to build. You want to build the Hardware Configuration and Logic, nothing else. You don’t want to put anything to Permanent Flash Memory or anything like that. Okay, so select that and Build in Progress. Your ultimate goal is to get this into Run Mode. Once you do get it into Run mode there are two other features to note.

Step 5: Checking the Toggle Switch

You should now be in Run Mode. To review, there are no other ports, just the one port and the toggle switch. (see image below)

The toggle switch is the Output Enabled, Run and Module Stop.
In this illustration the setup begins in 1) Run with Outputs Enabled (all 3 LEDs light up solid) and by clicking the toggle switch down one level to 2) Outputs Disabled, (the top 2 LEDs light up solid) and clicking down one more level  to 3) the Controller is Stopped (only the top LED lights up). This tells you that the LEDs work and the toggle switch works.

Step 6: Checking the Memory Protect Switch

The last feature is of course the Memory Protect key on the top, it’s the Memory Protect Switch and when you turn it on, the LED turns on to indicate the memory is protected telling you that that feature
works. (see image below) This completes the test.

Step 7: Additional Steps if Necessary

So, if this is a processor that you feel is giving you problems what you should typically do is let the processor Run overnight or over a weekend, or for a couple days. What you’re hoping for is that the processor is still in Run Mode when you return.
If for some reason it kicks itself out of Run Mode voluntarily you want to go into Proficy Machine Edition go to Target and one of the features there is Diagnostics, click on Diagnostics and your Info Viewer table will come up and tell you what the reason is that the processor kicked out of Run Mode.
So, if it’s something that you’re able to understand and get through, that’s great. If not, sometimes the errors can be confusing to understand that’s something you can contact us about.
