Desenvolvimento de uma interface de comunicação entre servidores OPC DA e clientes OPC UA.

Abstract

The OPC UA standard was developed to replace Classic OPC to eliminate dependence on the Windows platform and allow users to handle complex data and systems. However, the implementation of the Classic standard was very successful, especially the OPC DA specification. Because of this, the OPC UA is designed to allow smooth migration from the Classic OPC. One of the migration strategies is to use applications that allow the exchange of information between the two standards. In this work, a Wrapper application was developed to allow an OPC UA client to access data provided by an OPC DA server. The development was performed in the Visual Studio IDE using the .NET platform and specific SDKs for OPC UA and OPC DA.
