NOTE
With the P, Q sign parameter in the function block General, the sign of the following measured values
of the respective function group can be inverted (see Chapter 9.2 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.
Parameter: Min/Max cyclic reset
•
Default setting: (_:107) Min/Max cyclic reset = yes
Parameter Value Description
Yes Cyclical resetting of the minimum and maximum value memories is activated
No Cyclical resetting of the minimum and maximum value memories is deactivated
None of the following parameters are visible
Parameter: Min/Max reset each
•
Default setting: (_:108) Min/Max reset each = 1 day
Parameter Value
Description
1 day to 365 days Resetting of the minimum value and the maximum value, cyclically on all specified
days, for example each day (1 day)
Parameter: Min/Max reset minute
•
Default setting: (_:109) Min/Max reset minute = 0 min
Parameter Value
Description
0 min to 1439 min Resetting the minimum value and the maximum value at the specified minute of the
day, which is stated in the parameter Min/Max Reset takes place every, for
example 0 min (= 00:00)
Parameter: Min/Max days until start
•
Default setting: (_:110) Min/Max days until start = 1 day:
Parameter Value
Description
1 day to 365 days Indication of when the cyclical reset procedure of the minimum values and
maximum values begins, for example in 1 day (after the parameterization)
