How to send and receive sms using omron CPM1a PLC

[arcon_reveal]

Hello, I am using syswin 3.4, and I am unable to send and receive sms using omron cpm1a PLC.

My questions is, can anyone tell me or give me an example of a ladder diagram used to activate my serial port of my PLC when an output is activated?

For a start the CPM1A is pretty antiquated now. I do not even know if you can send an SMS with - probably could with a lot of work.
I would suggest you upgrade to the CP1L and then I can point you to some ladder for sending SMS and even how to set up the modem.
