Examples for module 2
10597
Task 1:
The digital output signals of the AS-i slaves 1 and 2 are to be transmitted. 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 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.
