Invalid values to RDB archive

[giorgiob]

In my project (wincc-oa 3.14) RDBmanager archives dpe value changes to Oracle db.

If I query HISTORYVALUES tables, I can't find values with invalid property set: in fact, no column exists for storing this attribute.

How is possible to archive on RDB also invalid values?

Thanks.

For a value not every status bit is saved on its own. Status information is saved as 64 bit word.
