Develop OPC UA applications on Android with the Prosys OPC UA SDK for Java. This updated guide shows how to get started with Android SDK API 35, including a simple client example. Please note that testing on Android is limited, so full interoperability with all OPC UA systems cannot be guaranteed.
At Valio, product quality and traceability requirements are at a very high level, highlighting the importance of smooth and reliable communication between different production systems. To meet these requirements, Prosys OPC developed the OPC UA standard based software Valio uses for integrating all their automation and manufacturing execution systems.
This master’s thesis recap examines how OPC UA Role-Based Access Control (RBAC) can be implemented in industrial automation. It compares directory integration with local role mappings, outlines their benefits and challenges, and presents findings from a simulated case study. The results highlight practical considerations for strengthening OT network security with OPC UA.
