[?]: Send Sms from S7300

[Pokajy]

Hi

I want to send sms from s7-300. WHich hardwares do I need for that?
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.

Previously I made communications between c# and s7300.
Is there any sinaut or siemens hardwares for this work? Also if it's possible to send sms without pc,it'll be better.
What do we need? gsm modem and a simcard?
Or a membership to gsm company and internet connection?
What is best solution?

Hello. thanks for answer.
I'll try these.

I also found another cheaper solution. 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

Well, "cheaper" means a lot of things. If you spend a month to make it work, instead of a few days, then it's not cheaper.
The cost of the materials is one thing, but what Umencho said is what you asked for:

Also if it's possible to send sms without pc,it'll be better.

Keep in mind also that your system is not really very self-sufficient, since it depends on a PC (and we all know how reliable PCs are...)

Good luck

P.S. If possible, try SCL. You will make your life a lot easier working with strings (among other things)

Don't be angry my friend. It was just another idea.
I know with pc, system sux.That's why I wrote at the beginning:

Working a pc, For only sms works does not sound good also
