VDMA OPC Machine Vision: OPC UA Demonstrator introduced
Published on : Monday 18-11-2019
Frankfurt, November 18, 2019 – As part of a joint project, members of the VDMA OPC Machine Vision Initiative together with the OPC UA Foundation, have developed a hardware demonstrator that includes the practical implementation of the "OPC UA for Machine Vision (OPC MV) Part 1 Companion Specification".
“From the point of view of automation technology and factory-IT, this specification represents enormous progress. Image processing systems are among the most complex components in machine building. Their integration is considerably simplified by manufacturer independent uniform methods for control and data administration,” says Dr.-Ing. Peter Waszkewitz, Software Project Manager, Robert Bosch Manufacturing Solutions GmbH 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 handles the administration of recipes, configurations and results in a standardised way, while the contents remain manufacturer-specific and are treated as a black box. The demonstrator establishes an infrastructure layer that enables a simplified and uniform integration of all possible image processing systems into higher-level IT production systems (PLC, SCADA, MES, ERP, Cloud, ...). It demonstrates the generalized control of a vision system and abstracts the necessary behaviour via the concept of a "state machine".
Partners of the project are: ASENTICS GmbH & Co. KG, PEER Group GmbH, Robert Bosch Manufacturing Solutions GmbH, VITRONIC Dr.-Ing. Stein Bildverarbeitungssysteme GmbH and VDMA Robotics + Automation.
