Dear All,

I am working with an ET 200SP remote station:

ET 200SP

CPU 1512SP-1 PN

(6ES7512-1DK01-0AB0)

with an Analog Input module, Voltage:

ET 200SP

Analog input module

AI 8xU BA (6ES7134-6FF00-0AA1)

In the manual and in different multimedia sources it appears that when the detection of open cables or lack of voltage in the modules is configured, if the OB82 is not present, the CPU goes to STOP. In my case, this doesn't. I generate the fault, the fault indication LEDs light up, in the CPU and the module, but the CPU does not go to STOP, I attach a screenshot. What am I missing to configure or if the ET 200SP station has the characteristic of not going to STOP when it detects this fault? I clarify that in these tests, the OB82 block is not loaded in the program.

The other query, when I place the OB82 block with the load of the variables to determine which is the faulty module, what type of fault it is and in which channel. I generate an overflow fault in channel 6 and in the variable CHANNEL = 32768 = 0b1000 0000 0000 0000, not coinciding with the channel in which I forced the fault. Could it be that this module does not identify the channel in which the fault occurs? Do you have any document to recommend studying on the subject of the different OBs and in particular the OB82?

Thank you very much

Cheers

Juan

I didn't find that info in the manuals. I am not finding the correct manuals.

Thanks again, Stefan
