Hi all,
I'm wondering if it is possible to connect a cellphone direct to the plc communication port#1 and let it send out a sms with a custom function.
I have try this with the cellphone connect to the pc serial port and this works fine.(at-command via hyperterminal)
Is there somebody who knows how to write a custom function so that the following command is sent out to the plc communication port#1
AT+CMSS=1,,145[enter] so that the cellphone sent out an sms from memory 1.
Thanks in advance
GREGOR
