Slave lists
For the diagnosis of the AS-i system the controllere provides lists for every master:
LAS = list of active slaves
LDS = list of detected slaves
LPF = list of slaves with periphery fault
LPS = list of projected slaves
Each of the different slaves lists is stored in four words (word no. 0...3).
In the following table you will find the addresses of the four words in which the corresponding slave
lists are stored.
Word no.

*) LAS and LPS have no slave 0, so these values are set to 0 by default!
Examples
:
Information about standard slave 16 is stored in word no. 1, bit no. 0.
Information about slave 28B is stored in word no. 3, bit no. 12.
