3.1.6.2.4 Processing of the SUPI3 Input StatERR
The StatErr input of the SUPI3 is used for detection of errors in the periphery
by the PLC. The bus coupler switches the input to active (=0) when an internal
error or a diagnostics message has been detected. This input remains active
until the cause for the error has been eliminated. This is the case for standard
bus couplers when a data bus error is no longer present. In a bus coupler with
advanced diagnostics function the input is not de-activated until the error
buffer has been exported completely.
