Wire Harness Manufacturing
New OPC UA Companion Specification published
The OPC UA Companion Specification for wire harness manufacturing (OPC 40570) has been officially published. The standard is the result of a joint initiative by the VDMA Productronic and Machine Information Interoperability departments in collaboration with the OPC Foundation. The project was supported by the government-funded ARENA2036-VWS4LS project, among others.
The aim of the new specification is to standardize digital communication between machines and manufacturing systems in wire harness production. This should improve interoperability, make processes more efficient and increase overall effectiveness in production.
The OPC 40570 specification is based on the existing OPC UA for Machinery standard (OPC 40001) and also integrates elements from the ISA 95 standard for job control (OPC 10031-4) and the OPC Foundation's basic device standard (OPC 10000-100). Among other things, it includes functions for machine identification, status monitoring and job management.
The first version of the standard focuses on processes in the cutting room, including cutting, stripping, crimping and sealing. An extension to other areas of wire harness production is already being planned.
In addition to wire harness manufacturers, the software provider DiIT and the machine manufacturers Komax and Schleuniger were also involved in the development. The prostep ivip group VES-WF supported the standardization process by providing data models.
The new specification is intended to enable a further step towards networked and future-proof production in the wire harness industry.
