Database Provider

The database provider stores SQLTags in an open format in the specified database. This provider type does not execute tags- it simply models tags and monitors values driven by a different tag provider elsewhere, such as an Ignition gateway using the database driving provider or FactorySQL.

Settings

Database

The database connection where the SQLTags configuration is stored.

Poll rate

The rate (in milliseconds) at which to poll the tag database for changes in tag value or configuration.

Poll overlap

The amount of time to overlap polls by. If set to 0, the config scan will look for changes only since the last execution. However, on databases that do not support millisecond resolution or are performing less-than-optimally, this could result in missed changes. This setting will expand the window in order to avoid missing these changes.
