Hi
I am using Siemens s7-300 and I amtrying to work out how to read the output data from a sfb 52 block.
I have a IM151-8F CPU connected trough PROFINET to a IM151-3 PN

ID:2042 (7fa(hex)) whitch is my diagnostic address for the IM151-3 PN unit
INDEX: 800A
RECORD: P#DB2.DBX0.0 BYTE 50

I need help to interpret the data in my DB. what does it say???

The whole reason for this is to have a "watchdog" of the node and modules. It might be the wrong sfb to use for this? I woul'd be greateful for any suggestions you might have.

I attatched a screenshot you could have a look at.
