OPC - What is it?
OLE for Process Control (OPC) draws a line between hardware providers and software developers. It provides a mechanism to provide data from a data source and communicate the data to any client application in a standard way. A vendor can now develop a reusable, highly optimized server to communicate to the data source, and maintain the mechanism to access data from the data source/device efficiently. Providing the server with an OPC interface allows any client to access their devices.
There are 3 standard types of OPC servers available on the market:
- OPC Data Access server , i.e., the efficient reading and writing of data between an application and a process control device flexibly and efficiently;
- OPC Alarm & Event server , i.e., the mechanisms for OPC Clients to be notified of the occurrence of specified events and alarm conditions, and
- OPC Historical Data server ,
i.e., the reading, processing and editing of
data of a historian engine.
