Introduction to the OPC standard

“

- [Narrator] OPC stands for Open Platform Communications. It is the interoperability standard for the secure and reliable exchange of data in industrial automation and manufacturing. OPC is a platform that ensures the seamless flow of information among devices from multiple vendors. An example you see on the screen showing two devices, one from Siemens and one from ABB. The OPC Foundation is responsible for the development and maintenance of this standard. Here is an example. If I have data coming from sensors connected to a PLC to a local computer within the factory floor and I want to display the data in a display monitor in the control room. In this case, I can use an OPC software to enable and facilitate the exchange of data between the two devices. So OPC stands for Open Productivity and Connectivity in industrial automation. It is a powerful tool that is used in the applications where they need to access data from any data source and then present them in any other devices.
