Detailed Description

OPC UA node component for accessing individual data points on an OPC UA server.

Represents a single OPC UA node with read, write, and subscription capabilities for real-time data exchange. Automatically synchronizes node values between Unity and the OPC UA server based on configured read/write settings. Use this component to map OPC UA server variables to Unity game objects for visualization and control. Configure the NodeId to match your OPC UA server's node identifier and set read/write/subscribe options as needed.
