1 Scope

OPC 40082-4 describes the data model for dosing systems as part of a plastic & rubber production cell/line (e.g. extrusion/injection moulding) for data exchange with manufacturing execution systems (MES) and other components of the cell/line. Dosed materials may be granulate, powder or liquids. For liquid silicon and rubber dosing systems, please refer to OPC 40082-3: LSR Dosing Systems. This specification is applicable for dosing systems mounted directly on the machine as well as for systems not directly mounted on the machine (e.g. floor-mounted).

The target of OPC 40082-4 is to provide a unique interface for dosing systems from different manufacturers to ensure compatibility.

The following functionalities are covered:

General information about the dosing system (manufacturer, model, serial number…), current configuration and status.

Process information like throughput for monitoring and process optimization.

Closed loop controls between the components of the production cell/line.

Following functions are not included:

Safety related signals like emergency stop
