6 Filter_InterfaceType

6.1 Filter_InterfaceType Definition

This OPC UA ObjectType is used for the root Object representing a filter as part of an extrusion line. It is based on the ExtrusionDeviceType (defined in IOC 40084-1) and formally defined in Table 1.

The instance(s) of Filter_InterfaceType shall be located under the Machines Object of the Server (see OPC UA for Machinery).

NOTE: If the OPC UA server is implemented in the control of the filter so only one instance of Filter_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 Filter_InterfaceType will be created.

The BrowseName of the object instance shall be “Filter_<Manufacturer>_<SerialNumber>”.

Example: “Filter_Erema_0123456”.

6.2 DeviceClass

The DeviceClass Property in the Identification Object inside the ExtrusionDeviceType shall have the value “Filter”.

6.3 FiltrationFineness

Fineness of the finest screen in the filter. (Example: 24 µm)

6.4 Area

The sum of all screen and filter areas [cm², inch²]

6.5 WasteOutput

Information on the filtrated material which is filtered out of the melt [kg/h, pound/h]. The MonitoredParameterType is defined in OPC 40083.

6.6 SpecificWasteOuput

Information on the filtrated material which is filtered out of the melt regarding to the throughput [%]. The MonitoredParameterType is defined in OPC 40083.

6.7 Drive

This object gives information about the drive of the filter. The DriveType is defined in OPC 40083.

6.8 BackflushPressure

With this Property the backflush pressure of the filter is set.

6.9 HydraulicPressure

This Object controls the hydraulic pressure of the filter. The MeasuringDeviceType is defined in OPC 40083.
