The Historian module performs automated data logging to SQL databases, and others. You can also use the Datasets module to store data in SQL, but the Historian module has a simplified configuration, with the database tables automatically created and a built-in connection with the trend charts.

The system can also use the information on the historian on the .NET scripting, get past values on tags or graphic displays or export the data.

The following sections describe how to configure data logging:

Adding Tags for Data Logging.

Configuring Historian Tables.

Historian Tables Schema.

Visualizing Trend Charts.

Customizing Getting Samples.

You can select any SQL database, such as Microsoft SQL Server, Oracle, MySQL or any OLEDB or ODBC compliant database to store the data. By default, FactoryStudio uses an embedded SQL database (TatsoftDB) that has a maximum capacity of 10 GB, for information on how to select the historian database, see Historian Database Provider.

When using OSIsoft(tm) PI System, there is no need to do any Historian configuration to access the data stored in the PI System, see Using OSIsoft(tm) PI System.
