Integration with other AVEVA products

The Historian is an open relational database for plant and process data. Many of the features of the Historian allow it to be used with many other products from AVEVA.

The Historian can store data from any application that supports SuiteLink™. Examples of AVEVA applications that can send data to the Historian are Application Server, I/O Servers, and InTouch WindowViewer™.

Any client application that can retrieve information using SQL can retrieve data from the Historian. For example, some AVEVA products that can retrieve data by means of SQL queries are the InTouch HMI, Historian Client applications and controls, Manufacturing Execution Module, and AVEVA Batch Management products. The Historian further extends SQL to improve the ability to handle time series data.

Also, the Historian I/O Server (aahIOSvrSvc.exe) is an interface for clients to access current data values from the Historian by means of the SuiteLink protocol. The Historian I/O Server can update items with current values for given topics, providing "real-time" I/O Server functionality.

Finally, you can use InTouch to configure the Historian by importing tag definitions and I/O Server definitions from the InTouch Tagname.x file into the Runtime database.
