OPC UA Methods
The OPC UA client can control the system using OPC UA methods. Methods are called (invoked) and return the result after the functions are completed (whether they are successful or not). Each function call requires specific input arguments.
The following function calls are available:
SetAreaPreset sets the preset lighting scene in an area. A preset scene recalls all the lighting channel levels in an area at once. Fade time is in milliseconds.
