I can not set up comms via Port 1 on a V700 Unit to a Cybertec SMM-400 Modem for SMS purposes.
Have set them Modem Serial Setting to 9600,8,n,1
I have check the Serial Port settings in the PLC via Information Mode. PCOM,RS232,9600,8,n,1
When ever I Init the Mode, It always returns "Modem operation Failed - Modem not connected"
Firstly has anyone used the Cybertec SMM-400 Modem successfully before and if so can you please provide the PIN OUT for the cable.
I have tried using "Putty" on the output from Port 1 when doing a Modem Init but nothing is transmitted..is this normal.?
Thanks in advance
