Remarks

 

QuickOPC-UA provides static classes with standard Node IDs defined by OPC Foundation: UADataTypeIdsUAMethodIdsUAObjectIdsUAObjectTypeIdsUAReferenceTypeIdsUAVariableIds, and UAVariableTypeIds. You can use properties of these static classes to easily specify “well-known” nodes you need to refer to, for example, the “ObjectsFolder” node which is a common starting node for browsing.

There are following classes with standard Node IDs for OPC-UA:

When you need to pass a standard node to any method, simply use the corresponding property from the static class, such as UAObjectIds.ObjectsFolder.

You can use the command-line OpcCmd Utility (installed with QuickOPC, or downloadable separately) to:

  • Get standard name that corresponds to OPC UA Node Id
  • Get the OPC UA Node Id that corresponds to given standard name
  • Display tables of node IDs and their standard names
  • Filter the tables to find out matching names.

See Using OpcCmd Utility for Static OPC UA Operations.
