Hello, in the S7-200 there is an FB to for sending an SMS to the MD720-3 modem. But I cannot find an FB the received or acknowledge SMS.
The idee is when the S7-200 sends an alarm-SMS, the receiver GSM needs the send an 'acknowledge SMS' back to the S7-200 program. When not, the S7-200 will send an SMS to another persons GSM and so on...
Maybe with S7-300 ?
Thanks and kind regards
