are:
List of active slaves (LAS)
The AS-i/INTERBUS gateway adds an entry for every slave, that can be ac-
cessed to.
List of detected slaves (LDS)
This list has an entry for every slave found while activating the network.
Liste der projektierten slaves (LPS)
This list was written by the INTERBUS master to configure all slave expected
by the control program of the master.
The AS-i/INTERBUS gateway switches the LED CONFIG ERR on, if a slave was
projected or detected during the start-up, but is not active. This means in normal
operation mode the failure of a slave.
