OPC (OLE for Process Control) is a technology of object linking and embedding for industrial automation industry. OPC technology identifies a universal way to share a data in monitoring and control systems. Developed by the OPC Foundation as an industry standard and published in the form of specifications.
The main and most demanded standard is OPC DA (Data Access). It provides the specifications for communicating real-time data between control devices.
OPC technology defines two classes of programs: the OPC Server that interacts directly with the hardware device, and the OPC Client that retrieves data from the OPC Server for further processing and transmitting commands to the OPC Server.
Any OPC Client can communicate with any OPС Server, regardless of the device which interacts with the specific OPC Server.
Thus, OPC-technology provides consumers the independence of the presence or lack of drivers or protocols. It allows you to select hardware and software that best responds the real needs of the business.
Application of OPC specification in industrial automation eliminates conflicts of access to equipment. It becomes possible to use several OPC-clients to retrieve data from a single source.
