24.1 PIDParameters

PID Parameters as array if several input signals (sensors) are used for the control.

0:DoubleD parameter

24.2 AutomaticControllerMode

Determination if PID Parameters are determined by auto-tuning itself (TRUE) or can be manually adjusted (FALSE).

24.3 AutoTuningActive

This Property informs if the automatic tuning is currently active. TRUE during automatic tuning, FALSE when automatic tuning is finished (new PID parameters are set, if necessary). If an error occurs during automatic tuning, the PID parameters will not be changed, AutoTuningActive goes back to FALSE and an alarm may be sent.

24.4 AutoTuningOn

Description:Starts the self-optimisation of the controller.

Signature 

	AutoTuningOn ();

The method has no Input- or OutputArguments.

24.5 AutoTuningOff

Description:Stops an already active self-optimisation process (no control parameters are changed)

Signature 

	AutoTuningOff ();

The method has no Input- or OutputArguments.
