For the communication between different machines, manufacturer independent information models are required. For plastics and rubber machinery, these information models are based on OPC UA, a communication framework developed and provided by the OPC Foundation. While OPC UA provides the technology for the transfer of information, the definition which information is transferred in which form is fixed in Companion Specifications.

This recommendation defines a Companion Specification for general information regarding plastics and rubber machines. The intention is that ObjectTypes which can be used for several machines and applications are defined only once. For specific applications (e.g. connection of injection moulding machines to MES), it is extended by specific Companion Specifications (e.g. OPC 40077).

Please find below the specification and model files of the Release 1.03 (1 June 2021) which is identical to OPC 40083 (Release 1.03) and VDMA 40083:2021-08.
