OPC server development is more difficult than OPC client, the development of OPC server mainly applies COM technology, the main application of books for Pan write "com Getting started and applications", a lot of technology has a great reusability, after the development of a program, Basically all the stuff can be reused and republished.There are three ways of dev

I. Operating environment: WIN7 (OPC interface under the WIN_XP configuration need to install plug-ins, sorry not to fix, now only the Win7 system 32 bit under the tutorial)Because OPC (OLE for Process Control) is based on Microsoft's COM (COmponent Model), and OPC's remote communication relies on Microsoft's DCOM (distribute COM), The security side relies on Microsof's Windows security settings.By communica

When you are doing OPC communication, you often encounter two situations:1) When using a opcclient to connect multiple opcserver on a remote computer on the same computer, one of the opcserver is found to be unobstructed, but the other opcserver do not work anyway. Do not know how to locate the problem? 2) Multiple manufacturers of opcclient connected to the same computer on the opcserver, found some opcclient pass, some do not pass, some can obtain d

I learned a bit about. Net, exactly, but also with this. And many vc6,vb6,vb on the internet. NET but, few C # 's. Now look at this and give an example: Test platform, is Vs2008,kepserver,opcnetapi.dll and OpcNetApi.Com.dll. Of course I also installed at the same time, Siemens Net2006 and STEP7, where Net2006 is responsible for OPC, may create some DLLs in the system, and so on, because my program to switch to a machine without Net2006 sinc
