Select fixed setpoint by direct or binary selection
The converter distinguishes between two methods for selecting the fixed setpoints:
1. Direct selection:
You set 4 different fixed setpoints. By adding one or more of the four fixed setpoints, up
to 16 different resulting setpoints are obtained.
Figure 8-13 Simplified function diagram for directly selecting fixed setpoints
Additional information about direct selection can be found in function diagram 3011 in the
List Manual.
2. Binary selection:
You set 16 different fixed setpoints. You precisely select one of these 16 fixed setpoints
by a combination of four selection bits.
