OLE for Process Control

OPC (originally OLE for process control) is an industry standard created with the collaboration of
a number of leading worldwide automation hardware and software suppliers working in
cooperation with Microsoft. The standard defines methods for exchanging real-time automation
data between PC-based clients using Microsoft operating systems. The organization that manages
this standard is the OPC Foundation.
The OPC Specification is a non-proprietary technical specification that defines a set of standard
interfaces based upon Microsoft's OLE/COM/DCOM platform and .NET technology. The
application of the OPC standard interface makes possible interoperability between
automation/control applications, field systems/devices and business/office applications.
Traditionally, each software or application developer was required to write a custom interface, or
server/driver, to exchange data with hardware field devices. OPC eliminates this requirement by
defining a common, high performance interface that permits this work to be done once, and then
easily reused by HMI, SCADA, Control and custom applications.
Previously: Drivers must be installed several times to connect to different devices
With OPC: OPC Client/Server creates a common interface for connecting to different
devices
