Failed to write csv files to Proficy Historian 5.0

894 Views Asked by At

I was able to import the csv files containing the tags for the data collector of the proficy historian 5.0. However, every time I tried to import data formatted in csv, it always failed and the error was "Error adding value [OUTSIDE ARCHIVE ACTIVE HOURS, -12]". I doubt this issue comes from wrong formatting of the CSV file and I'm guessing if I change some setting of the historian, it could be fixed. Am I on the right track here? Thanks for your ideas!

Propably Proficy Historian isn't letting you to write data to a read-only section. You should increase the archive parameter Data is Read-only after. Its a parameter of hours, prior to now, for which data can be stored in a read/write archive. After the time expires, that portion of the archive file is automatically made read-only. Incoming data values with timestamps prior to this time are rejected. A single archive file, therefore, may have a portion made read-only, another portion that is read/write containing recently written data, and another that is unused free space.

The simplest way to change the Data is Read-only After (Hours) is to run the Proficy Historian Administrator, click Data Stores then Data Stores Options and then increase the number of Data is Read-only After (Hours)
