Base Query (Base Query)
A base query feeds base components to a schema, which the query resolves against the schema one at a time. When used with
a relative schema, the base query allows you to limit the scope of your query and to scale within that as you add new points
or components.
The Base Query component is located in the palette as part of any of the relative schema components (for example, BasicRelativeSchema, RelativeHistorySchema, and others).
In addition to the standard properties (Status and Fault Cause), these properties support the Base Query.| Property | Value | Description |
|---|---|---|
| Base Query | text | Defines the scope of the query. |
| Publish Interval | hours, minutes, seconds | Specifies the amount of time between query executions. It triggers a complete publish output (of every returned component) at the interval selected. |
| Last Publish Count | read-only | Indicates the number of times the query executed. |
| Last Publish Time | read-only | Indicates the last time the query executed. |
