OPC Clients and Servers

Open Platform Communications (OPC) is an interoperability standard for exchanging real-time process data. This software includes a variety of OPC client and OPC server features that you can use to exchange data between your project and other OPC-compatible systems.

"OPC" originally stood for "OLE for Process Control" because the standard depended on Microsoft's proprietary DCOM and OLE technologies. As the standard has evolved, however, it has moved from those proprietary technologies to cross-platform technologies like SOAP for web services. The latest version of the OPC standard is OPC Unified Architecture (OPC UA).
