This is a new minor release of Prosys Sentrol. It improves minor details of the OPC UA server implementation.
The traditional PLC, Historian, and MES stack no longer meets the needs of modern industrial software. This article explores how an Industrial DataOps layer simplifies system architecture, centralizes data modeling, reduces integration complexity, and creates a scalable foundation for cloud analytics, AI, and future manufacturing applications.
Mipro worked with Prosys OPC to enable advanced OPC UA diagnostics for Finland’s first commercial digital railway project. Using Prosys Forge, Mipro extended the capabilities of safety PLCs to meet EULYNX SDI requirements, providing features such as OPC UA Reverse Connect, standardized information models, event-based communication, and automated data mapping. The solution improved interoperability, reduced integration complexity, and enabled reliable collection and transmission of railway diagnostic data, supporting safer and more efficient railway operations.
