Data interpretation
In each transmitted byte, the digital signals of 2 AS-i slaves can be transmitted. The position of
the data in this memory range depends on the AS-i address of the corresponding slave.
Therefore the value to be set is based on the highest AS-i slave address of the used digital
output slaves and not on the number of used slaves. The following table shows the allocation of
AS-i slave addresses to the module settings. The data range of the AS-i slave address 0 is not
used.

Examples for module 2
Task 1:
The digital output signals of the AS-i slaves 1 and 2 are to be transmitted. To do so, to which
value must module 2 be set?
Solution:
The highest used AS-i slave address is 2. According to the table, the data of the AS-i slave 2
are stored
in byte 2
of the module. Therefore, module 2 must be at least set to the value
2
.
Task 2:
The digital output signals of the AS-i slaves 5, 17 and 30 are to be transmitted. To do so, to
which value must module 2 be set?
Solution:
The highest used AS-i slave address is 30. According to the table, the data of the AS-i slave 30
are stored
in byte 16
of the module. Therefore, module 2 must be set to the value
16
.
