Tags in Ignition

Description

Tags are points of data and may have static values or dynamic values that come from an OPC address, an expression, or a SQL query. They also offer scaling, alarming, and meta information facilities. Historical Tag data is stored in the database connection associated with the selected history tag provider. Ignition creates and manages several tables within the Tag database that the historian uses to not only store your data but also make it easily available within your Ignition projects. There are several types of Tags that are similar in their configurations, but differ in how the value is generated. The different types of Tags are: OPC Tags, Memory Tags, Query Tags, Complex Tags, System Tags, and Client Tags.
