The page contains information that allows you to get a general view of the features that OpenSCADA can perform at this time. The functions are grouped according to application areas. To get a general picture there also includes scheduled functions or functions that are currently being implemented. The page also contains the requirements of OpenSCADA for its execution and building.

1 Areas of application OpenSCADA

Separating to the employment areas was made to simplify perception of the program functionality in light of traditional area of the project OpenSCADA — automation of technological processes. But also there possible mixed and specialized configuring of the program for real-time data operation, for example into areas: ERP, Billing, Smart House and etc.

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 to work on MS Windows® platform and implementing the work with OPC-DA by system DCOM, there will appear possibility for applying OpenSCADA into the gate OPC-DA -> OPC-UA role, which means free integration of old systems to the new or accumulation systems.
