Information
This component writes scalar data to the specified node as part of the request defined by the WriteNodeList it is connected to.
Data is written as the type specified by uaRealType, and the node must hold data of that type.
See OPCUA.Interfaces.Node for how to specify the node identity and handle errors.
Parameters (5)
