Hi Florian,

here at DESY we have a couple of S7-300 and S7-1200/S7-1500 PLCs. All of 
these
are connected to EPICS via the s7plc Support from PSI. More info you can 
find at

http://epics.web.psi.ch/software/s7plc/

This works great for us, but you need to have a communications processor 
connected
to your plc. For the S7-1200 this is built in. For the S7-300 you need, for 
example, the
CP 343-1 respective the CP 1543-1 for the S7-1500.

In my opinion the s7plc is the more secure way, because you send a dedicated
number of variables to your plc. The s7nodave writes directly to the memory 
of the
plc. If I am wrong here please correct this, but I don’t like the idea that 
someone
writes into the memory of my plc ;-)

Greetings, Joachim
