Configure the engineering units catalog

Engineering units can be application-specific, so AVEVA Historian must know how to relate these units to canonical definitions of engineering units. The Engineering Units Catalog is used to define the relationships between different units of measure, enabling support for converting between related units of measure.

Using the Engineering Units Catalog, you can define dimensions, unit systems, and how to convert between units within the same dimension. Defining these entries and correctly specifying unit conversions can take some care, so AVEVA Historian has preconfigured the catalog with the entries we expect most applications will need.

You can hide units for unit systems and dimensions that aren't used at your site, making it easier to configure the association between engineering units and their canonical units in the catalog.
