6.3.13 DS207 data set for flexible logbook access
Via data set DS207, the historic data, such as the load profile or the events stored in a
logbook, can be read out of a PAC device.
This data set only applies to the SENTRON PAC devices. The corresponding slot/subslot
address must therefore be used for reading.
You can find more precise information about the load profiles and logbook events in the
Manual (Page 9) of the relevant PAC device.

The "data log identifier" is defined system-wide for all PAC devices. With it, the data memory
in the PAC device to be read out can be selected.
The "Data Identifier" and the "OID (Object ID)" determine which data from the selected data
memory are sent in the response data sets.
