SE&Aflunkie Posted September 11, 2004 Report Posted September 11, 2004 (edited) S7-200 How do I triger or diagnose my modem, I have already utilized the modem wizard to set up the rest of the program. I am trying to send a text message to a cell phone to indicate that a "machine down" situation has occured. I can trigger the modem to achieve a tx/rx via the "leds" but no ringing on the receiving phone. Does anyone have a simple modem program to achieve the above desired results?

Chris Elston Posted September 11, 2004 Report Posted September 11, 2004 I don't program Siemens, but modems are modems. I assume you'll want to setup an ACSII driver from your PLC to your modem. The only way I know you can do this is use modem AT commands. In my example: Read here: http://www.mrplc.com/kb/index.php?page=ind...x_v2&id=67&c=12 Download here: http://forums.mrplc.com/index.php?&act=Down...&CODE=02&id=293 I load up AT commands in the ACSII string regsiters of my PLC and send them to the modem. I am sure you can do the same. The only part I don't know is sending a "text message" I am sure that can be done through modem AT commands and ASCII, but I am not sure off the top of my head. Quote
