Hi all,
I have a s7-200 plc connected by USB/PPI calbe 6ES7 901-3db30-0XA0 using WINDOWS XP PRO SP3.
I am able to manage and work with plc using MicroWin .
I downloaded the last version of libnodave-0.8.4.6 and I tried to connect with some exe test file as testPPI.exe under "win folder", but I am not able to reach PLC. I used also .cs file in order to create my application but the connection doesn't work. I noted that cable it's not posted (using device managment windows) under LPT/COM but under HID (human interface device): maybe this the problem? If yes, did you have suggestion in order to estabilish a connection with plc? maybe here the error "(libnodave.setPort(args[0],"9600",'E)". any suggestion are welcome!
Hoping for answer and thank you in advance,
best regards,

Luciano
