Automation of Things Posted April 8, 2019 Report Share Posted April 8, 2019 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 Brian Quote Link to comment Share on other sites More sharing options...
