24 V auxiliary supply
Recommendations
When slaves use a 24 V auxiliary supply, the disappearance of this supply is not managed by the TSX SAY 100 module.
Information on the disappearance of this supply can be accessed by using a 24 V input.

Multiple addressing
Recommendations
When one or more slaves are connected, make sure that you do not assign an address which is already being used by a slave on the bus.
If slave address is doubled then two scenarios may occur:
1. The two slaves with identical addresses have the same profile and manage identical I/Os: the AS-i master bus does not detect any error.
2. The two slaves with identical addresses manage different I/Os: the AS-i master bus can detect transmission errors when accessing the I/O from one of the two slaves.
