OPC.UA_Register.Nodes.Request

Description

This indicates detection of the OPC Unified Architecture (OPC UA) RegisterNodes Request command.
OPC Unified Architecture is a communications and data modeling standard for the exchange of information. It is a set of OPC specifications that unifies the older specifications into a new set. It provides the capabilities of Classic OPC and is backward compatible with it. It uses multiple data transportation methods like TCP/IP, HTTP and XML SOAP.
The RegisterNodes Service can be used by clients to register the nodes that they know they will access repeatedly (e.g. write, call).
