I need to send sms from M340 plc through a gsm modem(simcomm). can anyone provide a program to do this? I am having doubts regarding what to send in place of the ENTER and CTRL-Z commands (in hyperterminal)
I don't have any experience with Schneider PLC-systems but CTRL+Z and ENTER are easliy represented by hex-codes:
CTRL+Z = 1A (HEX)
ENTER (Carriage return) = 0D (HEX)
Hope this helps, if you need more help let us know!
