2.3.5 Using the Parameter Selection Bit Field
Changing parameter values in the ekr CON 600 net web guiding
controller is made using special communication objects, which are
named with EkrIn_.... The parameters whose values are to be
changed in the controller are selected by means of the Parameter
Selection Bit Field.

Fig.8: Using the Parameter Selection Bit Field
To change the value of a specific parameter in the controller, the
corresponding bit in the Parameter Selection Bit Field of the associ-
ated communication object (EkrIn_...) must be set to the High state.
The values of parameters whose bits have the Low state in the
Parameter Selection Bit Field are not changed or evaluated in the
controller.
