The SIMATIC S7-200 components used in this application example are currently phased out.
This application can be realized as easily and quickly with the new SIMATIC S7-1200.

Furthermore, many useful applications with SIMATIC S7-1200 are available here: 35923253

Task description and Solution  
Several remote S7-200 controllers are to be managed from a central station using the SINAUT MICRO SC remote control system. Data exchange is to take place via GPRS using the GPRS modem MD720-3. In the central station, the WinCC flexible 2008 RT HMI system is to allow to visualize and operate the remote S7-200 stations.

At the same time, important process data is to be editable on a PDA. Changing the process data is to be possible only after entering a login consisting of user name and password.

To operate a SIMATIC S7-200 with a MODEM MD720 along with the Telecontrol Server Basic, revised/new block libraries are available under the following link 99522310.
