Function Introduction AS-i data
51
Data distribution of the single slave with profile S-6.0.x in the M4 controllere (analogue mode)
The slave modue contains 2...4 successive slave addresses with binary data which together represent
an analogue value.
Slave:
Number slave
addresses
Data length
bit stream
Slave profile for …
1st slave 2nd slave 3rd slave 4th slave
2 8 bits S-6.0.A S-6.0.5
–– ––
3 12 bits S-6.0.B S-6.0.6 S-6.0.5
––
4 16 bits S-6.0.C S-6.0.7 S-6.0.6 S-6.0.5
Controllere:

1 input c 1 output channel (if less than 4 slave addresses only partly used and always
filled from left (D15) to right (D0))
Example: first slave address = 3 and data length = 12 bits

* Data bit D15 = bit with sign

therefore the highest slave number always provides the sign of the
analogue value and the 3 most significant bits of the analogue value.
