TimeSeries Configuration

The TimeSeries Configuration table is the master registry of historian tags. Historian tags are digital IDs which relate to a specific measurement on a specific well. The TimeSeries History table is related to this configuration registry table by sourceId.

Each timeseries configuration entry belongs to a single well. The well is specified in this table as sourceWellId. Each well can have 1 tag of each measurement type (e.g., WHP, OILRATE).

The unique constraint on this table is sourceId, meaning that the sourceId (tag identifier) must be globally unique.

TimeSeries Configuration for a given sourceId must be added to the system before attempting to add TimeSeries History to that sourceTimeSeriesId
