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.
