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).

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
