i also need .net opc dll client files.

Normal OPC da/hda automation dll files can be retrieved from ex. kepware or matrikon opc server after installation.

The files on OPC foundation are only available to registered non free users, not for registered free users.

Hi gmg320,

You need to install SIMATIC NET.
You can find the DLLs and OCXs after that if you are using microsoft visual studio to develope some applications.

with rgds,
