What is OPC?
OLE for Process Control (OPC™) is a set of specifications defined by the OPC Foundation. These specifications define a standard way to connect any field device to a generic man-machine application.
This standard consists of a set of software interfaces based on Microsoft OLE/COM technology.
The OPC specification uses a client-server approach:
- The OPC server provides a software interface to handle OPC objects.
- The client application monitors and controls the objects using standardized methods.
An OPC compliant client application is able to communicate to any OPC server. For example, sensors, valves and PLC systems.
