Wow no replies? Anyone know about this here?
Hi,
Sorry to reply lately.:cry:
You can use OPC ActiveX to connect to your OPC Server.
You can create application to read/write OPC tags in OPC Server.
There are many of OPC ActiveX you can find. A low cost ActiveX control with unlimited tags capable I know is COPC32. Pls visit http://www.scadathai.com to download it and try. You can see the tutorias how to use it with VB,VB.NET and C# too.
