Example: Communication object EkrIn_Setpoint
The figure below shows the allocation of the different parameters
to the Parameter Selection Bit Field using the example of the
EkrIn_Setpoint communication object. A description of this commu-
nication object can be found in chapter EkrIn_Setpoint, page 37.

Fig.9: Using the Parameter Selection Bit Field with the EkrIn_Setpoint communic-
ation object
The EkrIn_Setpoint communication object is used to write the set-
point values for the different guiding modes.
For example, using the Parameter Selection Bit Field it is possible
to transmit a telegram to the controller in order to change the set-
point for edge 3 (Setpoint E3) via Parameter Selection Bit Field
Bit2 = 1, without changing the setpoints for edge1 (Setpoint E1)
and edge2 (Setpoint E2) via Parameter Selection Bit Field Bit0 = 0
and Bit1 = 0.
