Hi Luis, I forgot to tell you that if you want to access through WWW you could have to forward ports of the router where the PLC is conected. |

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 |

Dear friends EUREKA, I just tried to access to s71200 over internet and web server works great!!!! I sugest the following procedure: Step 1. Create a web server application and download it to S71200 Step 2. Testing web server application in LAN
Example: IP address of my PLC is 192.168.0.12 (Subnet mask 255.255.255.0., Router 192.168.0.1) I type in URL tab: http://192.168.0.12
Step 3. By Static IP address from your Internet provider,
Step 4. Router settings
(My router settings in attachments)
Step 5. Remote testing
(80 - port number) Step 6. ENJOY!!!... Dragan MarinkovicGreetings from Belgrade, Serbia

I tested again, and web server works... Today I tested two CPU-s: 1. CPU 1212C dc/dc/dc (6ES7212-1AE31-0XB0) - Firmware V3.0.1 2. CPU 1215C dc/dc/dc (6ES7215-1AG31-0XB0) - Firmware V3.0.1 I use simple router D-Link DI-524 If you wish to access only to default S71200 web page (not user define page), you just need to enable web server and you must correctly setup IP adresss, Subnet mask, Gateway(router adress) in PLC Properties. Also, you must correctly set the router as we have previously noted.... Best regards Dragan Marinkovic AttachmentPLC settings.zip (2071 Downloads) |

Thanks on explanation, only after forwarding port 443 my web server started to work over static IP address. Svaka čast na objašnjenju, spasio si me danas! :-) Pozdrav, Miloš |
