OPC UA (IEC 62541) is the modern, secure, vendor-neutral protocol for industrial data exchange. ScadaHud ships a first-party OPC UA client built on the OPC Foundation .NET Standard SDK so you can connect to any compliant server without a side-load runtime.
Czym jest OPC UA?
OPC UA is the successor to classic OPC (DCOM-based). It runs over TCP and HTTPS, supports encryption (Basic256Sha256, Aes256_Sha256_RsaPss), certificate-based authentication, hierarchical address-space browsing, subscriptions with monitored items, historical data access, alarms and conditions, and a rich type system. Every modern PLC vendor (Siemens, B&R, Beckhoff, ABB, Rockwell, Schneider) ships an OPC UA server in its controllers, and most edge gateways expose data via OPC UA as the default northbound protocol.
