Dear Oscar, I work these procedure (in following text)with some industrialdevices several monts ago. I'm not sure,but I think that S7-1200 is also one of these devices. Router creates a firewall between your internal LAN and the internet. A firewall keeps unwanteddata from the internet away from your computers or industrial devices (S7-1200)in LAN network. You must configure router so that the computers on the Internet can communicate to computers on LAN. Usualy, most router have capability that alove you to communicate from internet only with one computer (device) on LAN. This feature they call DMZ (De-Militarized Zone). A DMZ allows aS7-1200 on your LAN toexposeto the Internet. But first you must configure your router.You mustwrite in DMZ settings IP adress of LAN port (IP adress of your S7-1200) when you connect S7-1200. Ofcourse your internet providermust give to you static IP adressfor your router (not dinamic) and when you access to that IP adress you will automaticaly access to your S7-1200. When you want to setup your roter, you must connected him with ethernet cable to your PC, and then open some internet browser (Internet explorer, Mozzila, Opera...) and in address bar write address for router settings(you will find these adress in router manual: usualy http://192.168.0.1), and after that you must enter username and password (usualy Username is:Admin, password: Admin).

Also used VPN and Remote Desktop Connection. Good and easy solution to connect remote LAN. |

Hi Here is a link to a VERY useful site: http://www.portforward.com/ , which is - you guessed it - about Port Forwarding. Port Forwarding is the procedure you use in order to bypass the Router Firewall so you can access specific (IP addresses/ Ports/ Machines) inside a network. You've got to have a basic understanding of computer networks, but fortunately for those of you who don't, there is plenty of information online (try google, wikipedia, etc.) @OP, you can also use Wireless Antennae, in order to create a one-on-one link through wireless. No router configuration, no VPN, no port forwarding, just you and your PLC. I have succesfully used Ubiquity Networks NanoStation, to create a remote SCADA over Wireless, using PLC S7-1200 and a Basic Touch Panel. Although deifferent from your application, I don't see a reason why this shouldnt be working flawlessly in you situation That way, you completely avoid any wired LAN, so if there is no Internet access available, you solve your problem. If you are concerned about security (which you should, IMHO), then you shouldn't be using any connectivity at all, but if you absolutely must, take care to secure your network. Encryption is your friend here. HTH |
