Is it possible to connect Siemens S7-224 to GSM modem (Siemens TC35i) through RS 232? Does anyone have an application or technical data about connection S7-224 with GSM modem to send SMS?
 
Yes, it is possible to connect CPU224 to TC35I GSM modem then you can send SMS to a cellphone or to another CPU. Actually, I have already installed a system of this kind and the programming is very simple, you can find the example at the siemens website, or you can email me then I will send you a copy of the program.
