Using a GSM Modem attached to your ClearSCADA Server doesn't require any third party software and the communication can be two way. You can send SMS messages out of ClearSCADA and you can also receive SMS Messages into ClearSCADA. Recommended Hardware: Schneider Modem SR2 MOD02Note: Not all GSM Modems work
I altered the ClearSCADA pager communications channel settings as follows to match the modems defaults. The paperwork that came with the modem didn't give me this vital information. So I found this information in SR2MOD02 and SR2MOD03 Wireless Modem User Guide 11/2013 on page 45 of a manual that I downloaded.
Baud Rate = 115200
Data Bits = 7
Parity = Even
Stop Bits = 1
Flow Control = RTS/CTS
To send and receive SMS Messages you need to use the Pager Driver in ClearSCADA.
The online help gives some good information regarding this and can be found here
