The term Active Setpoint is used to describe the currently selected setpoint of a controller. Some controllers can use the main Local Setpoint or an Alternative Setpoint.
The alternative setpoint can be another local setpoint or a remote setpoint sent from an external device. Only one setpoint can be active at a time.
On controllers that incorporate a Profiler / Programmer feature, the active setpoint value is controlled by the profiler function when a profile program is active.
