Parameter sets (controller parameters)

The parameters for the controller channels determine the control characteristics of the
respective control loop. These parameters must be adapted to the prevailing conditions of
the process for stable control behaviour. So that conditions can be changed for each
controller channel to be adapted in order to keep the control performance stable.
The best parameter settings can usually be found by the automatically adjusting the
controller. However, this only works for linear processes.
For operating the controller, see
For nonlinear processes (control systems), it is recommended to set the parameters
manually.
The following table provides an overview of the parameter sets of the controller channels.
