If someone calls plc phone number, plc won't accept the call and it'll be missed call. then plc will send actual informations to phone number. Is there any sinaut or siemens hardwares for this work? What do we need? gsm modem and a simcard? Or a membership to gsm company and internet connection? What is best solution? if it's possible to send sms without pc,it'll be better.

I tried it but it did not work yet. 1-Connecting nokia phone to pc with usb data cable 2- installing gsm modem drivers. then pc see it as gsm modem (com3 forexample.) 3- connecting to plc and reading plc values with a c# project. 4- sending sms with c# project via gsm modem. I found several c# project for sending sms. program finds phone but it doesn't work well. anyway. I'll try with md720-3. In my head I have two questions. 1- I want to analyse which number calls. There will be a number list. Forexample Phone1-Mr Arnold Phone2-Mr Jack.. etc. if arnold calls, it'll send the sms for arnold. if someone which is not in the list calls, it won't send sms. they won't have to send sms to get sms.they will just call the number. plc wont accept and it'll be missed call. then plc will analyse the number. otherwise it'll be bad programming. 2- Also I want to read integer values from messages. forexample arnold will send sms, he will write "pump3 40" then pump3 will be setted to 40Hz. etc. Indeed sms is great. But we have to spend some time on programming. I hope someone can help about this two messages. Code examples will be great. Thanks

The GSM data must be data card, so there isn't possible to call it. Take a look deeply in this example. Unfortunately this is not regards C#... Best regards, Hristo Mihalev
