Automatic addressing via the AS-i master
Single Slave
For automatic addressing, the address is specified by the AS-i master. For a Single Slave, the
master checks which slave has address 0 and assigns it the next free address. This address is
also written to parameter p2012. If more than one slave has address 0, an automatic
addressing is not possible.
Dual Slave
For automatic addressing, the address is specified by the AS-i master. If both slaves have
address 0, the second slave is hidden and the control assigns a valid address for slave 1.
Slave 2 then becomes visible with address 0 and can be addressed.
Automatic addressing is not always possible for older AS-i masters. In this case, use the
manual addressing and set the address from an addressing device, via Startdrive.
Further information is contained in the AS-Interface system manual, Section "Setting the AS-i
address"
Addressing via the addressing device (e.g. 3RK1904-2AB02)
Addressing via the addressing device is made offline.
Further information is contained in the AS-Interface system manual, Section "Setting the AS-i
address"
Addressing via parameters
The address assignment is made with the p2012[0] and p2012[1] parameters.
If you assign the address via a commissioning tool, you must back up the settings so that they
are not lost if the power fails.
