3.4 Address assignment
Before connecting to the AS-Interface bus: assign an
unused address to each slave.
Note
Permitted address range for each slave:
– Standard slave: 1 ... 31
– Extended address mode slave: 1A ... 31A, 1B ... 31B
Factory setting (address allocation):
– Slave 1: 1 or 1A respectively
– Slave 2: 2 or 1B respectively
No parametrisation of the AS-Interface slaves
(not necessary).
Address both slaves one after the other at the plug
"AS-i In"
Warning
Never assign the same address to both slaves.
The assignment of the data bits to the inputs and outputs
of both independent slaves is shown in the following
diagram.

Outputs:
I/O = Bidirectional (B)
The address mapping depends on the configuration of the
master.
