Functional characteristics and demands of OpenSCADA system

The page contains information allowing to receive general representation about functions which the OpenSCADA system can carry out by the current moment. Functions are grouped on spheres of application of OpenSCADA system. For reception of a picture as a whole of functions planned or make now are included also. The page also have demands of OpenSCADA system for it building and execution.

1. The employment area of system OpenSCADA

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


OpenSCADA system's roles (96 Кб)
Fig. 1. OpenSCADA system's roles


1.1. SCADA system's server



1.2. Station of the operator of technological process, the board of the dispatcher, the panel of monitoring, etc.



1.3. The environment of execution of controllers (PLC)

1.4. Universal OPC-UA server

Due implementation of the protocol OPC-UA into agent mode, OpenSCADA can provide 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 by 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.

2. Requirements for OpenSCADA

2.1. Execution

The demands to apparatus for OpenSCADA system execution at different roles viewed into table 1. The demands to programs for OpenSCADA system execution and it modules allow into table 2.


Table 1. The demands to apparatus for OpenSCADA system and it modules.

Role Demands
