B.1 Adding or Removing a Component to/from a Compressed Air System

During the lifetime of a Compressed Air System, the manufacturer, integrator, or operator may wish to replace, add, or remove Components to or from the system. The OPC UA provided Services AddNodes and DeleteNodes can add or remove Nodes from the AddressSpace during runtime of the OPC UA Server and are described in OPC 10000-4. If the manufacturer of a Compressed Air System wants to enable an integrator or operator to add or remove Components while the OPC UA Server is running, at least those two Services shall be available to both the Server and the Client. To additionally support the edge case B.2, the whole NodeManagement Service Set, defined in OPC 10000-4 shall be supported by both the Client and Server.

If the used Server or Client does not support the Services AddNodes and RemoveNodes, the modelled Compressed Air System shall be changed while the OPC UA Server is not running. The OPC UA Server shall only boot up after the required mechanical work is done.
