Hello, A possible solution is to use GPRS for the remote stations. And an Internet connection at the central location. Have a look to the SINAUT ST7 system in this example: http://support.automation.siemens.com/WW/view/en/23810112 and more specially the volume 2 using GPRS For smaller CPUs (S7-200) there is also a SINAUT Micro solution: Here an example. http://support.automation.siemens.com/WW/view/en/22537809 |
