OPC - Client


A software program that is used to contact and obtain data from a Server software program either on the same computer or on another computer. A client makes a request and the server fulfills the request.

An easy example of a client would be an e-mail program connecting to a mail server or an Internet browser client connecting to a web server.

In the case of OPC,
  • an HMI/SCADA Screens may be a client application that connects to an OPC sever.

  • an HMI/SCADA's Database may be a client application that connects to an OPC sever.

  • OPC Client driver from any vendors may be a client application that connects to an OPC sever. So in this case the OPC Client may be I/O driver that provides the interface and communications protocol between OLE for Process Control servers and your process control software.
