For class mapping, there are three different sheets. BaseClassMapping, LeafClassMapping for SCTYPE, and LeafClassMapping for SKEY.

Base Class Mapping

The BaseClassMapping worksheet contains a list of all the AVEVA Diagrams "Types", and corresponding OpenPlant class name values. Values in the column OpenPlant "Class" can be changed.

Example: Aveva Diagrams Component of type <SCNOZZLE> is mapped to OpenPlant <NOZZLE> class

Leaf Class Mapping (SCTYPE)

This mapping tab specifies mapping for the GTYPE property and a pair of properties GType.SCSType, which provides a proper OpenPlant ClassName.

Example: Component with attribute GTYPE = “REDUCER” is mapped to OPPID “PIPE_REDUCER” Component with attributes GTYPE = “REDUCER”, SCSTYPE = “CONC” is mapped to OpenPlant class “CONCENTRIC_PIPE_REDUCER”.

Leaf Class Mapping (SKEY)

This mapping tab specifies mapping for GTYPE property and GType.SKEY combination, which provides a proper OpenPlant ClassName.

Components, not mapped by these 3 attributes are mapped according to BaseClassMapping. GTYPE.SKEY mapping has the highest priority, followed by GTYPE.SCSTYPE, and then BaseClassMaping is applied.
