[[OLE for process control|OPC]] technology follows a set of open standards specifications, created and managed by the [[OPC Foundation]], to ensure [[interoperability]] between devices and systems in industrial automation and within other enterprise systems.
The origins of OPC are based on [[Microsoft]]'s OLE, COM and DCOM technology and today's OPC set of standards allow field systems and other devices, automation and control applications and business applications to communicate acquired real-time and historical data and records to enterprise systems and between production devices from multiple vendors. The standards are evolving and are created or rewritten to account for emerging technologies and trends.<ref>[http://www.opcfoundation.org/Default.aspx/01_about/01_whatis.asp?MID=AboutOPC OPC Foundation, "What is OPC"]
