I found the example program the get this from the CPU, no problem. I know that for the DI and DO, there is not much to say about. But for the analog, I don't just want the SF led, I want to get the fault for each single channel. I read through the manual to find about the SFC51 but I think with this CPU there is nearly nothing. Then I went to the OB82 and find that there is some Temporary bit/byte but I can't get a clear idea how to do it. And as well for the IM360 and 361 and channel problem of the FM350-2. I red on the module manual that there is data record, but I can't get my hand on it... Thanks for your help. PS: I hope to understand better how to the diagnostic can be read in every module

When a fault occurs, OB 82 is triggerd (must be in PLC or PLC will stop) In this OB you can write a program to show witch module has an error. see the attached helpfile for more information.

ArmandBaule Posts: 19 Rating: (0)	Hi, Thanks for you reply. I had already a look at it. But lets say I have an error on one of the following AI module (1,2,3,4) located in rack 3 slot 7... How can I know which one is faulty? I can get the module address (how to decode it) and how do I know which channel? Thanks for your help
