Experimental Physics and
Industrial Control System

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
