An initialization value can be set at the PV_IN input
or an external process variable in floating point
format can be connected.
Default: 0.0
Range of Values: -100.0...100. 0 (%) or phys.
value 1
The process variable in the I/O format is connected
to the controller at the PV_PER input.
Default: W#16#0000
The GAIN input sets the controller gain.
Default: 2.0
Range of Values: ³ CYCLE
The TI input determines the time response of the
integrator.

Range of Values: ³ CYCLE
A dead band is applied to the error. The DEADB_W
input determines the size of the dead band.
Default: 1.0
Range of Values: 0.0...100.0 (%) or phys. value
The PV_FAC input is multiplied by the process vari-
able. The input is used to adapt the process vari-
able range.
Default: 1.0
The PV_OFF input is added to the process vari-
able. The input is used to adapt the process vari-
able range.
Default: 0.0
A minimum pulse duration can be assigned with the
parameter PULSE_TM.
Default: T#3s
Range of Values: ³ CYCLE
A minimum break duration can be assigned with
the parameter BREAK_TM.
Default: T#3s
Range of Values: ³ CYCLE
