[Doğan Çiğnaklı]

Hi there, I am trying to communicate with s7-1200 plcs over python. And i am using this library. My system is w7-64bit and python3.7.1 amd64.

I installed snap7 using pip3 install and i downloaded the file named Misc and pasted snap7. dll my python folder after all i added this locations to path.

But when i add to my code plc1 = c.Client() or sth about snap7, i got this error :
OSError: [WinError 126] The specified module could not be found

Can anyone help me to fix it?

Regards.
