The basis of OPC is provided by several Microsoft technologies These technologies are. explained in the following section,OPC stands for OLE for Process Control. OPC is a standardized vendor independent software interface that allows data to be. exchanged between hardware and software One system can provide another system with. process data via OPC, OLE means Object Linking and Embedding the technology for embedding objects in.
COM means Component Object Model and is necessary for the use of OPC. COM is a central component of Windows operating systems and controls the interaction. between multiple software components By using COM the OPCserver effectively becomes. part of the Windows operating system and is therefore not dependent on file names storage. locations and versions, COM defines a standard that allows objects to be defined as self contained units in Windows. Basic knowledge of the general use of the PC programming device and of the use of the Windows operating system is required If you want to develop an OPC client application you will also need to be able to work with Microsoft Visual Basic or Microsoft Visual C Scope of the manual
