Hello,

We want to send / receive SMS between a GSM Modem (wavecom) and a SCADA (Wincc - Siemens).

So, we have the following questions:
1. How can we establish connection between modem and SCADA?

2. What scripts do we have to use to send and receive SMS?

Thanks in advance for your time

With Regards

First you need to install Cygwin, instructions here. Then install SMSTools3, instructions at the same page.

After those installations you have two folders: c:\cygwin\var\spool\sms\outgoing for outgoing messages and c:\cygwin\var\spool\sms\incoming for incoming messages. See the SMS file format for details.

You can simply put the message file into the outgoing folder, and SMSTools3 will send it.

To integrate SMSTools3 with WinCC you need to create suitable Add-on using languages and possibilities provided by WinCC. In case of alarms, Add-on could create a SMS message file into the outgoing folder. Also it could check if there are new messages available in the incoming folder, and do the actions based on the content of SMS. The scripting is done in the WinCC side, not in the SMSTools3 side. Therefore I cannot give any detailed instructions or sample scripts.

Thanks for the useful reply,

At the moment we have a little difficulties connecting the modem

So, when this part is done, I will inform you about the steps you suggested us
