Hi, you are a little bit wrong in this thread. Because the Micro Automation Sets are only for S7-200! But, in principle, the function is the same like with S7-300 PLC. You need this things: - 2 GPRS-modems f.e. MD720-3, each PLC one modem - 2 Quad Band Antenna - SINAUT MICRO SC or SINAUT ST7 Software for managing GPRS-Connections on a PCwith Internet access - programming S7-300 (please ask in S7-300 forum for a solution) The way how it works is this one: You connect your S7-300 PLC's via GPRS-modem to the Sinaut Micro SC Server. The Server manage the connections and allows communication between the PLC's. YOu also can set a visualization system, like WinCC or WinCC flexible, on the Server. It's allows you to watch and control process variables of all the connectet PLC's. You can read the documentation of the Micro Automation Set 21 or 31 to understand the working method, but you can't use the libraries because they are for S7-200. regards Robster Edit: I just found some links für S7-300 GPRS communication http://support.automation.siemens.com/WW/view/en/27038105 http://support.automation.siemens.com/WW/view/en/25545680 |
