Example 3: Two-setpoint mode with a synchronization controller without local / remote
switchover:
1. One variable setpoint w1 = c2 ∗ wE + c1
2. The setpoint w2 = c1 defined by parameterization and not affected by
the front controls
Both setpoints are thus linked by the fixed component c1; the switch-over
from w1 to w2 takes place simply by external switching off of w2. A setpoint
ramp Tw > 0 is provided.
