Since EIB/KNX presence detectors are available from a variety of manufacturers, the
name of the S-mode output communication object varies accordingly.

The state of the local presence detector on the digital input is mapped in the building
automation and control system via the following S-mode output communication object:

Master/slave applications:
Bindings are required in S-mode, in order to transmit the slave
presence detector status
to the master.
