When this option is activated, the current value of the data point, which can be set by the
master, is mirrored back from the station to the master. Furthermore, the trigger options
of the data point can be enabled to configure the triggering of the transmission.

Configuration of the data point index
The following rules apply to configuring the data point index.
● Data point indexes must be unique within each of the following object groups:
– Binary Input / Binary Input Event
– Binary Output / Binary Command
– Counter / Counter Event
– Analog Input / Analog Input Event
