I found one small example with usage of this object in Excel, but some parts are not running in VisualBasic. I'm looking for documentation of activeX "Siemens OPC DAAutomation 2.0". Can you help me, where I could find this? Nice day Marian

But you will surely find this document very usefull. Cheerz. Hope this helps.

On this site (kepware) you can found the VB/VB.NET examples, and you can use them to get access to WinCC OPC server. Just replace 'Kepware.KEPServerEX.V4' with 'OPCServer.WinCC.1'. WinCC RT must be running, when you want to connect to WinCC OPC server. http://www.kepware.com/KEP_KB/default.asp?ToDo=view&questId=84&catId=60 You can download trial version (2 hours running, then you must restart) of Kepware OPC server. Inside is also very good OPC client (writen in VB, with source code), which I always use to test my connections to OPC servers. In fact, it's very simple to connect from VB to OPC server, when your VB application and OPC server are on the same PC machine. But, when you have your VB on one PC and OPC server on another PC (server), there is pain in the ass to configure the connections, because of the DCOM settings (security).... Anyway, on the Kepware site you will found all you need (also for DCOM settings) to run VB application with OPC. Regards from sLOVEnia...
