This document is made to understand how the Tag Values can be logged for reporting and historical purposes by using Wonderware Historian, the same results can be achieved through using InTouch functionality. Historian provides an easy way to import InTouch tags for recording historical data to an SQL Server database, but this ease of use comes at a price through the licensing. With a bit of scripting InTouch can provide the same historical logging results without the need for Historian, plus the flexibility of using different data sources through ODBC.
InTouch version 7.1 or higher. For this example, version 10.0 will be used.
An ODBC data source. SQL Server 2005 will be used for this example.
