Data content
10639
Analogue output data of the slaves of the AS-i masters 1 + 2
The data of analogue output slaves with the following AS-i slave addresses can be directly written via
the modules 15 and 17:
1...31 (setting = 4 channels per slave),
1...31 (setting = 1 channel per slave).

So, module 10 only has to be used if the data cannot directly be written via the modules 15 or 17.
If an analogue output is written simultaneously via the modules 10 and 15 or 17, the modules 15 or 17
have priority.

Data interpretation
10640
Using module 10, analogue output 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 written must be given to
the controllerE via the fieldbus interface, in addition to the analogue value. The controllerE replies to
such a request with a copy of the request data. As a result, only one specific analogue value can be
transmitted at a time by module 10. This process is called multiplexing.
