Hello,
who can help me? I am a German student and I have to programm a simple, but asyncronous working, OPC client. The Example from the Borland-website is very difficult and I can't start it, because there are a lot of errors. I want to use this client to communicate with a Siemens S7-300. I have installed the OPC-Server and I have converted the VB examples from the SimaticNet-CD.
The simple example works, but I should use the asyncronous read and write. And what do the Callback-function?
I hope someone can help me or have any informations!
Regards,
Patrick Bruder
