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
