Hello all,

I would like to build an application, who will send and receive SMS (M874-3 <-> mobilephone). Hardware S7-300 (IM 151-8 or other), M874-3 without CP. For sending, I have found an example, but not for receiving. For receiving, are examples in TiA, but Im working with Step7 v5.5.

I already made an FB for receiving, but it doesn't work. Sample (FB18).

 Hi Otto_O

We are trying to use M874-3 to send a SMS. We used the sample project available in Siemens website. But we couldn't get it to work in a S7-300 PLC. were you able to send an SMS using a M874-3 and a S7-300 PLC?

If you have can you please upload the sample project you used?

Thank you very much
