Tip
All addresses in these further examples can only be retrieved as WORD ad-
dresses. A breakdown into single bits is only possible by copying the word to a
symbolic address and retrieving this bit by bit.

Query:
master 1, slave 16 / 16A
in the list of active slaves
output to LASSlave16M1
Example
Query:
master 2, slave 22B
in the list of projected slaves
output to LPSSlave22BM2

Tip
A flag word consists of two flag bytes.
Flag word %MW(n) corresponds to the flag bytes %MB(2n) and %MB(2n+1).
Example:
Flag word %MW21 corresponds to the flag bytes %MB42 and %MB43.
