Examples for module 1
10593
Task 1:
The digital input signals of the AS-i slaves 1...3 are to be transmitted. To which value must
module 1 be set at least?
Solution:
The highest used AS-i slave address is 3. According to the table, the data of the AS-i slave 3 are
stored in byte 2 of the module. Therefore, module 1 must be at least set to the value 2.
Task 2:
The digital input signals of the AS-i slaves 2, 13 and 28 are to be transmitted. To which value
must module 1 be set at least? Where can the data of slave 13 be found?
Solution:
The highest AS-i slave address used is 28. According to the table, the data of the AS-i slave 28
are stored in byte 15 of the module. Therefore, module 1 must be at least set to the value 15.
The data of slave 13 are stored in byte 7 in the bits 0...3.
