Limitations

Limitation Description

Optional object instance declarations are not created

For example, WSMachineType is an object of the Weihenstephan specification. It contains an optional object instance declaration (Counters), which is not created.

EU variables are duplicated when they are shared by different parents

When vendors declare an Engineering Unit variable and reference it from multiple nodes, the Engineering Unit variables are duplicated for each node that references the Engineering Unit.

Only one parent node is displayed

If you import an information model with nodes referenced by more than one node with an Aggregates reference or Organizes reference or inherited references, you import only one node.
