To integrate Plant SCADA data into AVEVA Historian, you initially need to identify the variables you would like to include within your Plant SCADA project.
The following variable types are supported:
-
Variable tags (digital and string types only)
-
Trend tags (SPC tags not supported)
-
Digital alarms
-
Time-stamped alarms
-
Analog alarms
-
Advanced alarms
-
Multi-digital alarms
-
Time-stamped digital alarms
-
Time-stamped analog alarms.
For each variable you would like integrated into Historian, you need to set the Historize field to "TRUE".

You then need to set up the AVEVA Historian Plant SCADA Connector to send your Plant SCADA data to AVEVA Historian. This includes configuring a Plant SCADA CtAPI server to provide data to the connector.
