3.7.1 Find function for checking the archive entries
The measurement period has more than a thousand and a few hundred entries respe c-
tively. In order to be able to display individual values from this amount of data for checking
purposes, the device has a find function for archive entries. Values can be sought in the
following columns:
·
Block number
·
Date and time
·
Counter reading
First, the search occurs by choosing the desired column (block number, date/time or
counter reading) in any archive line. Then pressing the "ENTER" key-combination enables
the input of the desired value in this column. After terminating the input with "ENTER" the
display skips to the archive line containing the entered value. If the entered value does not
exist, it skips to the entry most closely resembling the sought value.
3.7.2 Measurement period archive 2
Measurement period archive 2 is used for saving redundant measurement period archive
data. These are archived at intervals of the measurement period
MPer . The structure and
content correspond to the measurement period archive ArMP for standard parameterisa-
tion (see above). The archive structure cannot be changed. The archive has approx. 100 0
data rows which corresponds to a memory depth of approx. 40 days for a measurement
period of 60 minutes.
Measurement period archive 2 is not displayed on the device and can be read out with the
aid of the "WinPADS" parameterisation software.
3.7.3 Flexible archives 1 to 4
The archive structures of these archives are flexible and can be parameterised with the aid
