OLE for Process Control (OPC), which stands for Object Linking and Embedding (OLE) for Process Control, is the original name for a standards specification developed in 1996 by an industrial automation industry task force. The standard specifies the communication of real-time plant data between control devices from different manufacturers.As of November 2011, the OPC Foundation has officially renamed the acronym to mean "Open Platform Communications" although they also use the tagline "Open Productivity & Connectivity" on their website.
