Chapter 7 OPC Server

OPC Server

7.1

Introduction

OPC (OLE for Process Control) is the first standard resulting from the collaboration of a
number of leading worldwide automation suppliers working in cooperation with Microsoft.
Originally based on Microsoft's OLE COM (Component Object Model) and DCOM
(Distributed Component Object Model) technologies, the specification defines a standard
set of objects, interfaces and methods for use in process control and manufacturing
automation applications to facilitate interoperability.
There are many different mechanisms provided by various vendors that allow access to a
variety of devices via specific applications. However, if an OPC server is provided for the
device, other applications will be able to access the OPC Server via the OPC interface.
