Data content

Analogue input data of the slaves of the AS-i masters 1 + 2
The data of analogue input slaves with the following AS-i slave addresses can be directly read via the
modules 14 and 16:
1...31 (setting = 4 channels per slave),
1...31 (setting = 1 channel per slave).
Change of the setting:

So, module 9 only has to be used if the data cannot directly be read via the modules 14 or 16.

Data interpretation
10628
Using module 9, analogue input data of an AS-i slave with any AS-i address can be retrieved.
The information which channel of which AS-i slave on which master is to be read must be given to the
controller via the fieldbus interface. The controller replies to such a request with a copy of the request
data and the corresponding analogue value. As a result, only one specific analogue value can be
transmitted at a time by module 9. This process is called multiplexing.
