AS-i phases (status machine)
Offline phase: No AS-i data traffic takes place during initialisation.
Detection phase: In the detection phase, the AS-i master first of all searches for existing slaves -
irrespective of whether they are projected or not.
Activation phase: In this phase, the found slaves are activated depending on the operating mode.
Data exchange phase: The AS-i master carries out cyclical data exchange with the activated
slaves.
Management phase: At the end of a cycle the AS-i master goes into the management phase,
during which the master can send a command to a specific slave (if requested).
Inclusion phase: After this, the AS-i master goes into the inclusion phase, during which it sends a
command to a free slave address to detect new slaves.
