IO station failure (PROFIBUS DP or PROFINET IO)
The OB_DIAG1 / OB_DIAG1_PN block detects the failure of the station, and evaluates it
based on the event class and event number (see table).
In the event of a fault, the identifier for "higher-level fault" (OMODE = 16#40xxxxxx) is
entered for the OMODE output.

= 1
).
