Re: Connection to Siemens S7 PLC

[Pavel Masloff <pavel.masloff@gmail.com>]

Hello all,

Concerning Dirk's s7plc driver (SLS) which is written for linux only, has anyone tried to rewrite it for windows?
I am not that expert in drivers development, but I would be grateful if anyone could help me. 
>From what I can see, there are some header files (and corresponding libraries/functions) which are linux specific. For example, <unistd.h>,<sys/socket.h>, <netinet/in.h>. Perhaps, <winsock2.h> might do the trick?

Maybe someone has already tried to port s7plc to Windows platform?

Hi,

just a few thoughts about the S7. It is not possible to open a Step7 Project for the S7-300
or S7-400 with Step7 MicroWin. These system do not have anything in common than the
name and the vendor. S7-200 has a different architecture than the 300/400 system. And
therefore a completely different programming environment.

I have not tried yet, but I think the S7plc driver should also work with a S7-1200 System
because it is also TCP/IP.

With the CP 243-1 on a S7-200 it should also work, but you cannot use the example project
delivered with the S7plc software.

Greetings, Joachim
