5.4 Control via INTERBUS
Data exchange between the INTERBUS master and the UFI11A takes place using the
I/O area. The process data for all inverters connected to the UFI11A are located in a
contiguous block in this area.
If there is more than one inverter, the associated process data words are appended at
the end (see Fig. 23). The number of process data words per inverter is 3 words with
Autosetup.
The inverters are located in ascending (SBus) address sequence with their associated
process data lengths in the process image, for example an inverter with address 1 and
3 words, then an inverter with address 2 and 3 words, then an inverter with address 3
and 2 words, etc.
