1.4 Universal OPC-UA server
Due implementation of the protocol OPC-UA into agent mode, OpenSCADA can provide a popular function of the OPC-server to client's protocols, which supports and direct implemented into OpenSCADA. The function common uses on platform MS Windows®, and many SCADA-systems on the platform work exclusively with OPC—servers, as the data sources. Thus OpenSCADA can act as an universal OPC-server on Linux platform (Fig.2).
In plans. With adapting OpenSCADA for work on MS Windows® platform and implementing work with OPC-DA by system DCOM, there will appear possibility for applying OpenSCADA into gate OPC-DA -> OPC-UA role, which means free integration of old systems to the new or accumulation systems.
