"010146AF251D0BA9".
mydatalog4id

10.3.1.2 Data record compression
Data record compression can be activated via the optional
period=...
setting. This means that all
of the data records within the specified period are compressed with the per field adjustable
calculation method.
The calculation method must be specified in brackets after each field in the field list (see "Fields"
on page 98) of the xPath query:
https://{IP address}:{Port}/{xPath Query Table selection}/
(ch0(method=1)|ch0(method=2)|ch0(method=16;sum_mode=4))?{login}&period=15
