Welcome to AVEVA Historian

With AVEVA Historian, you can:

• Acquire data from a various sources
  Historian’s Data Acquisition subsystem offers high-speed data capture to acquire plant data from AVEVA I/O Servers, DAServers, InTouch HMI software, Application Server, and other devices.

  AVEVA Historian optimally acquires and stores analog, discrete, and string data. In addition, the SuiteLink protocol used by AVEVA I/O Servers and DAServers provides time and quality stamps as data is added to the system.

• Store lots of data efficiently
  The Storage subsystem compresses the data for maximum storage efficiency. In addition to your plant's data, AVEVA Historian stores alarms and events, summary data, configurations, security information, backups, and system monitoring data.

• Retrieve data when you want it
  The Retrieval subsystem responds to SQL requests for plant data and allows you to retrieve large amounts of data very quickly. It also supports REST and SDK data retrieval.

• Replicate your stored data for security
  The Replication subsystem replicates tags' values to other AVEVA Historian servers with high fidelity or calculates and replicates summaries of those values.

• Query data using time domain extensions to SQL
  AVEVA Historian builds on the capabilities of the SQL query language by supporting time-series data and controlling the resolution of returned data in SQL (for example, to give an evenly spaced sampling of data over a period of time).

• Create, save, and share graphical content
  AVEVA Historian includes a tool called Insight that lets you quickly search for data and generate clean, clear graphical content that you can save and share.
