Address assignment of the AS-i slaves

Address assignment can be done via the AS-i master or via an addressing device. AS-i slaves are usually supplied with address 0. Slaves that were added later are searched under this address, and an address is then assigned. Address 0 is not permitted during the data exchange phase.

The extended addressing is supported from AS-i specification 2.1, so that corresponding slaves can also be given the addresses 1B to 31B. 0B is not permitted.

Normal address assignment

New AS-i slaves usually have address 0. An addressing call command can be initiated via the parameter 0x2000 (AS-i command interface). However, the addressing call command only works if precisely one AS-i slave with address 0 is connected to the bus. A further addressing possibility is shown in the Quickstart section
