Web based control


Thread Starter


I'm doing a project about remote access to the PLC. I need to display I/O and also able to control it from the website. The PLC I use is FC640 from FESTO.

I'm thinking to use VB6 to read the data by using DDE server provided by FESTO. But I have no idea how to make it as a web application.

Is it possible to use VB.NET instead? I heard that .Net is no longer support DDE and I counldn't find any free OPCserver for festo too.

So these are the question
How can I make a web application from VB6?

Or What's the best way to communicate with the PLC if I use VB.NET?

Or any other suggestion
