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

6 Calender_InterfaceType

6.1 Calender_InterfaceType Definition

The Calender_InterfaceType is used for the root Object representing a calender 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 Calender_InterfaceType shall be located under the Machines Object of the Server (see OPC UA for Machinery).

NOTE: If the OPC UA server is implemented directly in the control of a calender then only one instance of Calender_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 Calender_InterfaceType will be created.

The BrowseName of the object instance shall start with “Calender”. It may be extended with additional information, e.g. a number (”Calender_1”) or manufacturer/serial number (“Calender_Bandera_0123456”).

NOTE: Clients will browse the root node by type and not by BrowseName.

6.2 DeviceClass

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

6.3 HorizontalPosition, VerticalPosition

Position of the calender from a reference point (e.g. floor for vertical position, centre of exit of feeding device (e.g. flat die) for horizontal position).

Unit: mm or inch

6.4 ProductForce

Force of outgoing product.

Unit: N or lbf

6.5 ProductTension

Tension of outgoing product.

Unit: N/mm² or lbf/in²

6.6 CouplingProductForces

Force of ingoing “sub product”

Unit: N or lbf

6.8 Rolls and Gaps

These containers represent the calender rolls and the gaps between them. The RollsType and GapsType are defined in OPC 40084-1.
