You need SINAUT hardware at the S7-300 (TIM-Modules) and the modem. (GSM or GPRS) Then you need SINAUT ST7cc which is an Add-on WinCC for your pc, plusa modem (dial up or gsm) for telephone lineor if you use IP-based network like GPRS at the remote CPUs then you need a DSL modem at the pc. You also need the SINAUT ST7 Configuration software to configurate your connections. Have a look at the following links where you can find schemas and description of these solutions. GPRS Solution (cost-optimised) http://support.automation.siemens.com/WW/view/en/38698845 GPRS Solution wich high data security (see 2nd picture and volume 2) http://support.automation.siemens.com/WW/view/en/23810112 FAQ, How to configure the GSM Modem for SINAUT ST7 (Telephone /GSM solution) http://support.automation.siemens.com/WW/view/en/29586028 More examples about SINAUT ST7 (Here you can find Info on how to conigure connections with SINAUT ST/ etc) http://support.automation.siemens.com/WW/view/en/22340652

SSE Posts: 45 Rating: (8)	Dear Ahmed Majeed, If non-Siemens solution is acceptable, I would suggestan EDGE-GPRS modem ER-75i. I have had several projects, including WinCC and PLC communications, and everything worked fine. A single hardware requirementyou need isan ethernet connection to WinCC station or PLC or whatever you want to access via GSM/GPRS.The modemsupports standard Windows VPN client, freeware OpenVPN software Best Regards
