parameter in the function block General, the sign of the following measured values
of the respective function group can be inverted (see Chapter 10.2 Structure of the Function Structure of
the Function, section Inversion of Output-Related Measured and Statistical Values):
•
Minimum/maximum values of the active and reactive power:
Min:Ptotal, Max:Ptotal, Min:Qtotal, Max:Qtotal
•
Minimum/maximum values of the average values of the active and reactive power:
AverageMin:Ptotal, AverageMax:Ptotal, AverageMin:Qtotal, AverageMax:Qtotal
Application and Setting Notes for Minimum/Maximum Values
The minimum/maximum values functionality is not preconfigured. If you want to use the functionality, you
must load it from the library into the respective function group.
The following settings listed for the calculation of the minimum/maximum values can be set with DIGSI or at
the device. You find the setting parameters in DIGSI in the project tree under Settings > Device settings.
