Trend and Historian
The Historian Module allows an easy setup to log process variables in SQL databases. A built-in embedded SQL database is supplied for small and medium size databases. Large systems can be configured to use Microsoft SQL Server, Oracle or any database compatible with OLE-DB, ODBC or ADO.NET.
FactoryStudio also has the option to use the OSIsoft PI System for the Historian server, with no programming required, complete integration and seamless access.
The graphical tools include a powerful Trend chart object with support for quality information, annotations, vertical charts, batch comparing and more.

The Trend Modulo allows you to compare two (or more) curves on the same chart from two different start times, ideal for batch and process analysis. Trend charts can be added to web and PDF reports, image snapshots and value data table exports are available upon operator commands or any process event.
 
Trend charts are out-of-box fully functional, yet completely customizable with Real-time SPC calculation.
