What does OPC stand for in the context of process control?

In the context of process control, OPC stands for Object Linking and Embedding for Process Control. This standard was developed to facilitate interoperability in industrial automation by allowing different software applications and devices to exchange data seamlessly. The inclusion of "Object Linking and Embedding" in the name highlights the standard's roots in Microsoft's technology, aiming to create a common framework for accessing real-time and historical process data from different sources.

Understanding this context is essential, as OPC has evolved to include various specifications like OPC DA (Data Access), OPC HDA (Historical Data Access), and OPC UA (Unified Architecture), which enhance its capability in modern industrial systems. OPC has become a vital component for integrating disparate systems, ensuring that various hardware and software components can communicate efficiently in a process control environment.

Other options do not accurately represent the official meaning of OPC in this context. For example, while "Object Linking and Control" might sound relevant, it does not encompass the specifics of process control. Likewise, "Open Protocol Configuration" and "Operational Process Connection" do not align with the established standard recognized in the industry.
