OPC UA Server Discovery

Discover available OPC UA servers on the network using opcuaserverinfo

When to Use

• Finding available OPC UA servers on the local network
• Getting the discovery URL or endpoint information for a known server
• Querying server security policies and supported authentication types
• Troubleshooting empty discovery results (LDS issues, certificate trust)
• Setting up prerequisites for OPC UA server discovery

When NOT to Use

• Creating OPC UA client connections (use opcua() directly)
• Reading, writing, or subscribing to OPC UA node values
• Configuring OPC UA connection security (message security, certificates)
• Working with non-OPC UA protocols (Modbus, MQTT)
• Discovering OPC Classic servers (OPC DA, OPC HDA)
