This OPC UA ObjectTypeis used for the root Objectrepresenting a melt pump as part of an extrusion line. It is based on the ExtrusionDeviceType(defined in OPC 40084-1) and formally defined in Table 1.

The instance(s) of MeltPump_InterfaceTypeshall be located under the DeviceSet Objectof the Server (see OPC UA Part 100).

NOTE: If the OPC UA server is implemented in the control of the melt pump so only one instance of MeltPump_InterfaceType will be created. But it is also possible that one OPC UA server is connected to several machine controls as one interface to the MES. In this case several instances of MeltPump_InterfaceType will be created.
