principles of remote connections to plcs

Spending a couple hundred upfront on the switchgear will save you a lot of messing around in the future. If all it takes is a router, I'd say that's a small problem to have.

not when you are stuck in the dessert in a foreign country and the client decided on remote access only when you got there. this thread http://www.plctalk.net/qanda/showthread.php?t=48386 names a very good looking product for what i need. will get this when i'm back in south africa. and come to install it afterwards

Ahh yep, I was going to suggest a 3G modem if you got coverage. Depending on which carrier you use, I've found 3G to be fairly reliable. If you need to do some minor monitoring of your network you can always get applications for your Mobile Phone too with 3G. Convenient for when you're on holiday and they want you to troubleshoot something... *Cough*
