Historian Variable Problem

Joao

Hello all,

I configured all my trend variables with "TRUE" in the column "Historize" and the values are inserted in the database correctly.

After that i configured some variables in variable list with "TRUE" in the column "Historize" but the values are not being entered in the database.

Any reason for not being in database?

Regards,

Parents
  • It would be good to raise this as an enhancement request. There is no technical reason why INT, REAL, etc. are not supported by the Variable tags to be Historized. I think the intention was that Customers would create Trend Tags for these. And for data types not possible to Trend, they provided access directly via Variable tags.
    Be warned though, with Variable tags, you don't have backfill capability like you get with Trends. So you want to make sure the Connector is online all the time.
