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.
i-GuSystem Ltd., a Finnish specialist in CNC program transfer and production data acquisition, adopted Prosys OPC UA Forge to extend its data integration from MTConnect into the OPC UA era, ensuring future-proof and scalable solutions. To meet the growing demand for OPC UA, i-GuSystem integrated Prosys OPC UA Forge as a future-proof layer. Forge enables direct OPC UA connectivity with output in XML, ensuring full compatibility with iguXMLsync and downstream systems like VisualFactory, MES, Azure cloud, and Power BI.
The first Forge deployment was completed in just two hours, delivering reliable results and proving the scalability of i-GuSystem’s solutions. By adopting Forge, i-GuSystem has seamlessly extended its CNC data expertise into the OPC UA era, future-proofing its architecture while continuing to provide rapid, hands-on results for its customers.
This is a new minor release of Prosys Sentrol. It improves minor details of the OPC UA server implementation.
