Control Loop
Single Loop Control provides basic feedback control using three term PID or On/off control. The controller output is calculated from the differenc
e
between the process variable and the control set point. The control set point can be a fixed value entered by the user, a value
from a remote source or a
value derived by the profile control algorithm.
