OPC is designed to deliver open connectivity via open standards
in industrial automation and the enterpris
e systems, and is based on a series of standards specifications. Originally based on Microsoft's OLE
COM (component object model) and DCOM
(distributed component object model) technologies, the specification defined a standard set of objects, interfaces and methods for use in process control and manufacturing automation applications to facilitate interoperability. OPC is supported by the OPC Foundation.
