Micrologix 1200 I/O error

4 posts in this topic

I am trying to troubleshoot a Micrologix 1200 error from afar....and am not having too much luck. Does anyone have any suggestions as to what could cause and 0189h error (I/O module error)? There is only the ML 1200 and an 1762-IF2OF2 module on the rack. Thanks in advance!

I very much appreciate your response. I have seen that somewhere, but my problem is that I had this unit working and set up correctly and my boss had gone out to train on site. So therefore, I don't know if he or the customer changed anything. But I will certainly have him check the dip switch settings....it's not possible to change the program without RSLogix right?

Change the 1762-IF02OF02 module. If bit S:1/8 is set, the error will be clear at power-up. good luck
