● If the updated value PV = SP, then the special function does not change the value of AQ.
● Dir = upwards (+) (timing diagram numbers 1. and 3.)
● Dir = upwards (+) (timing diagram numbers 1. and 3.)
– If the updated value PV > SP, then the special function reduces the value of AQ.
– If the updated value PV < SP, then the special function increases the value of AQ.
– If the updated value PV < SP, then the special function increases the value of AQ.
● Dir = downwards (-) (timing diagram number 2.)
– If the updated value PV > SP, then the special function increases the value of AQ.
– If the updated value PV < SP, then the special function reduces the value of AQ.
– If the updated value PV < SP, then the special function reduces the value of AQ.
With a disturbance, AQ continues to increase / decrease until the updated value PV again
corresponds to SP. The speed with which AQ changes depends on the parameters KC and
TI.
If the input PV exceeds the parameter Max, then the updated value PV is set to the value of
If the input PV exceeds the parameter Max, then the updated value PV is set to the value of
Max. If the PV falls short of the parameter Min, then the updated value PV is set to the value
of Min.
If the input R is set to 1, then the AQ output is reset. As long as R is set, the input A/M is
If the input R is set to 1, then the AQ output is reset. As long as R is set, the input A/M is
