VDMA OPC Machine Vision
Image processing - interoperable and manufacturer-independent
Together with the OPC UA Foundation, members of the 'VDMA OPC Machine Vision Initiative' have developed a hardware demonstrator that includes the practical implementation of the 'OPC UA for Machine Vision (OPC MV) Part 1 Companion Specification'.
"Machine vision systems are among the most complex components in mechanical engineering. Their integration is considerably simplified by standardized methods for control and data management across manufacturers," says Dr. Peter Waszkewitz, Software Project Manager at Robert Bosch Manufacturing Solutions and member of the core working group.
OPC MV Part 1 describes an abstraction of the generic image processing system, i.e. a representation of a so-called 'digital twin' of the system. It takes over the management of recipes, configurations and results in a standardized way, while the content remains manufacturer-specific and is treated as a black box. The demonstrator establishes an infrastructure layer that enables simplified and standardized integration of vision systems into higher-level IT production systems (PLC, SCADA, MES, ERP, cloud, etc.). It demonstrates the generalized control of a vision system and abstracts the necessary behavior via the concept of a 'state machine'.
Partners of the project are: Asentics, Peer Group, Robert Bosch Manufacturing Solutions, Vitronic and VDMA Robotics + Automation.
