Tag Logging question

Hi Gents,

I might repeat myself but I have an obsession on how to configure a TagLogging archive tag where values are combinations of a continuous cyclic analog tag (1s) and a raw archive tag (10x100ms). I can create 2 distinct archive tags but I want to combine these 2 in one.

Some background might explain the facts:

Both archives are fast (blob compressed format) and each record stores values begin-end archive_id. I don’t know how to insert/change these records to hold both archive values in one archive_id.

I doubt there is documentation about archive blob formats and WinCC ODK is as usual useless.
