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.
¿Qué es 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.
Lo que soporta el driver de ScadaHud
- OPC Foundation .NET Standard SDK (the canonical reference stack)
- Browse the address space, subscribe to nodes by NodeId
- Anonymous, username/password, and X.509 certificate authentication
- Sign and SignAndEncrypt security policies (Basic256Sha256, Aes256_Sha256_RsaPss)
- Configurable publishing interval, sampling interval, and queue size per monitored item
- Auto-reconnect with session restore
- Boolean, scalar numeric, string, DateTime, and array types
- Deadband filtering for analog tags
Casos de uso comunes
- Modern PLC integration (Siemens S7-1500 OPC UA server, B&R, Beckhoff TwinCAT, Rockwell ControlLogix via OPC UA module)
- Edge gateway northbound (Kepware, Matrikon, ProSys, Cogent)
- Building automation via BACnet-to-OPC UA gateways
- OPC UA over MQTT (PubSub) for cloud-bound deployments
- Vendor-neutral data acquisition replacing per-vendor proprietary stacks
