6.21 Setpoint Profiles
Most of the configured control loops can be operated with time-based setpoint profiles („control loop
profiles“). A profile will be entered into a table via the operator terminal. A profile can include step
changes and ramp changes with a maximum of 16 segments. Setpoint profiles can be started and
stopped at any time. At an active profile the current running time is displayed.
