Visual Basic Driver for Siemens S7-200


Thread Starter


Looking for a Direct communications Driver for Visual Basic 6.0 To communicate with Siemens S7-200 PLC's. Does anyone know if one exists?

We have recently added a driver to support the PPI protocol in our TAS-HMITalk ActiveX software. Feel free to download our product at so you can test how the driver works for you.

Let us know if you need any further assistance from us.

Can someone tell me how to use libnodave to communicate between and s7-200 CPU 226? I downloaded the file but I am not familiar with using dll in At least if I can get some references to use that it will be helpful.

I read the documentation in the libnodave package but couldn't use it for programming.

I look forward for a reply.

Thank you.
