siemens s5 + s7 on ethernet want acess each plc program via modem

hello

Currently have 4 x s7 400's and 3 x s5 115u's all conected via coms cards to ethernet going back to a scada.

What I need to do is find the best or most pratical way of being able to get online to each plc via a modem from a remote site.

Can I do it through the ethernet or do I have to do it through each individual plc's programing port.

Would appreciate any info on ethernet and conecting to plcs via modem and about any special siemens cards that could help us out

I know you can do what you want with the S7's, not sure abouit the S5's though, you might have to trawl your way through the Siemens support site to find the answer.

The S7 TS adaptor has been discused here before, here some links to those threads:-
