Description
SAMPLE TIME. The time between block calls has to be constant. The input "Sample time" indicates the time between block calls.
INTERNAL SETPOINT. The input "Internal setpoint" is used to specify the setpoint.
PROCESS VARIABLE IN / Actual value input. At the input "Actual value input", a startup value can be parameterized, or an external actual value can be wired in the floating point format.
PROCESS VARIABLE PERIPHERy / Actual value Periphery. The actual value in the periphery format is wired to the controller at the input "Actual value Periphery ".
MANUAL VALUE. The input "Manual value" is used to specify a manual value by means of the operator interface function.
PROPORTIONAL GAIN /Proportional coefficient. The input "Proportional coefficient" indicates controller gain.
RESET TIME / Integration time. The input "Integration time" determines the time response of the integrator.
DERIVATIVE TIME. The input "Derivative time" determines the time response of the differentiator.
TIME LAG OF THE DERIVATE ACTION / Delay of the
DEAD BAND WIDTH. The system deviation is taken via a dead band. The "Dead band width" determines the size of the dead band.
