PROFIBUS DP
10.1.3 I/O Data
10.1.3.1 Process data
In V2.1 mode the AS-i I/O data are mapped in the process data as known from
the Siemens and AS-i/InterBus masters. This means that the lower nibble de-
scribes the data of the AS-i slave with the higher slave address. The ec-flags or
hi-flags are additionally mapped at the nibble of AS-i slave 0.
