Mean Value Forma-
tion
The synchronisation instant within one hour, the time interval and the time interval for
averaging can be set via parameters.
The selection of the time period for measured value averaging is set with parameter
7611 DMD Interval in the corresponding setting group from A to D under MEA-
SUREMENT. The first number specifies the averaging time window in minutes while
the second number gives the frequency of updates within the time window. 15 Min.,
3 Subs, for example, means: Time average is generated for all measured values with
a window of 15 minutes. The output is updated every 15/3 = 5 minutes.
Under address 7612 DMD Sync.Time it can be determined whether the point in time
for averaging selected under address 7611 is to commence on the hour (On The
Hour) or is to be synchronised with another point in time (15 After Hour, 30
After Hour or 45 After Hour).
If the settings for averaging are changed, then the measured values stored in the
buffer are deleted, and new results for the average calculation are only available after
the set time period has passed.
