Configures the basic type of control required and the PID (see page 32) and Autotune (see page 30)
settings.
Selects the basic type of controller required.
Standard proportional, integral and derivative control.
A simple 2-state control.
Note. Loop 1 output type must be set to Time Prop – see page 35.
If the required controller action is known it can be set using this parameter. Otherwise it can be set to
Unknown and Autotune (see page 30) determines and selects the correct action.
For applications where an increasing process variable requires an increasing output to control it.
For applications where an increasing process variable requires a decreasing output to control it.
For applications where the control action is not known (run Autotune to set the control action
automatically).
