OPC UA Methods are defined by the method trigger of the OPC UA Server Plug-in. The methods appear with names and parameters in the OPC Router’s own OPC Server data point space and can be called by clients.
When a client calls an OPC UA Method defined in this way, the trigger is triggered in the connection that contains this method trigger. The input parameters of the trigger can be used in the connection and the output parameters can be described. The connection itself thus serves as implementation of the OPC UA Method.
