OPC-UA APPARATUS AND METHOD FOR UNIDIRECTIONAL DATA TRANSMISSION BASED ON OPC-UA

摘要

Disclosed is an OPC-UA based one-way data transmission apparatus and method. One-way data transmission apparatus for transmitting data from an OPC-UA server to an OPC-UA client according to the present invention receives information of a management target node from the OPC-UA server, and corresponds to a management target node by the OPC-UA server. A transmission proxy for receiving real-time data and historical data corresponding to the management target node by requesting the data to be managed, and the management target node information from the transmission proxy to establish an OPC-UA server proxy, and the transmission Receives the real-time data and the historical data from a proxy, and updates the real-time data and the historical data for the management target node using the established OPC-UA server proxy, and the OPC-UA client It includes a receiving proxy for transmitting data corresponding to the request of the OPC-UA client.
