 If the updated value PV  SP, then the special function increases the value of A.
 If the updated value PV < SP, then the special function reduces the value of A.
ith a disturbance, A continues to increase / decrease until the updated value PV again
corresponds to SP. The speed with which A changes depends on the parameters C and
TI.
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 A output is reset. As long as R is set, the input A/M is
disabled.
Sampling time
The sampling time is fixed at 500 ms.

For more information and application examples with application-related parameter sets for
