HaulOff_InterfaceType – OPC UA interfaces for plastics and rubber machinery – Extrusion

6 HaulOff_InterfaceType

6.1 HaulOff_InterfaceType Definition

This OPC UA ObjectType is used for the root Object representing a haul-off 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 HaulOff_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 halo-off so only one instance of HaulOff_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 HaulOff_InterfaceType will be created.

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

Example: “HaulOff_Weber_0123456”.

6.2 DeviceClass

The DeviceClass Property in the Identification Object inside the ExtrusionDeviceType shall have the value “Haul-off”.

6.3 Distances and contact pressures

The distances and contact pressures of the caterpillars/belts/rolls/… in the haul-off shall be put into the Object AdditionalMeasuringDevices which is part of the ExtrusionDeviceType.

6.4 Drives

This container collects the objects that give information about the drives of the haul-offs. The DrivesType is defined in OPC 40083.

6.5 Force

This Object controls the pulling force of the haul-off. The MonitoredParameterType is defined in OPC 40083.

6.6 ClampClosed

This Property describes the State of the haul-off.

6.7 OpenClamp/CloseClamp

These Methods are used to open/close the clamp. They have no input or output arguments.

Signature

	OpenClamp ();

Signature

	CloseClamp ();
