So it is very necessary to use the same standard to communication for both user and vendor.BR _fckxhtmljob=9OPC Data Access primarily provides vertical data integration and interoperability between measurement and automation systems on the manufacturing floor and client application. OPC client applications can communicate with one or more OPC servers from different suppliers. OPC Data exchange makes it possible by defining a set of interfaces that provides interoperability and allows data exchange among devices and controllers connected to Ethernet networks using different field bus protocols. BR _fckxhtmljob=9This text first analyzed OPCs general situation and its advantage, and understands various OPC carefully. On the base of understanding the structure of the OPC server and the realization procedure, designed an imitate true model experiment. Included the register and realization procedure of the server, and carried on a simple imitate true experiment, and proved the OPC software techniques openness. p class=Geg615/p BR _fckxhtmljob=9
