Store the number of the slave
station (n = station number), for
which the device-related diagnostics
are to be requested, in the
”Diagnostics address” byte; store
the code for ”device-related
diagnostics” (individual
diagnostics) for 8DI, 8DO and
8DO/2A” (code = 4) in the
”Diagnostics a 1” byte.
Load diagnostics word
Fault?
Evaluate fault in FBx.
The structure of the diagnostics word is as follows after requesting the de-
