5.3.11 Module 10
– analogue multiplexed output
Data content
Analogue output data of the slaves of the AS-i masters 1 + 2
Note
The data of analogue output slaves with the following AS-i slave addresses can be written
directly via the modules 15 (master 1) (
→ page
49
) and 17 (master 2) (→ page
56 ):

1...31 (setting 4 channels per slave),

1...31 (setting 1 channel per slave).
Change of the setting "Channels per slave" (→ page
93 )
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.
Direction of data
Bidirectional (2 words = 4 bytes in both directions)
Module settings
Value range 0 / 1
0 module is deactivated
1 module is activated (details → data interpretation)
Data interpretation
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.
Syntax:
Requirement: 4 bytes from the fieldbus interface to the controllerE

byte n 0 0 0 0 0 0 C C
byte n+1 M M X S S S S S
byte n+2 not used

MM master number (1 or 2)
X 0 = single or A slave
