tss Posted February 19, 2013 Report Share Posted February 19, 2013 I am trying to get a V120 to send an SMS message using a Wavecom WMOD2 modem but the port is never properly initialised. The error code is 2 (reply error). I have verified that the modem itself is working by sending SMS messages using Hyperterminal. One thing that might be an issue is that there is no built-in configuration for this modem, so I had to make my own which may not be correct. Does anyone have experience using this modem? If so, which commands did you use to initialise it? Should the PLC-side modem configuration just be the same as the port initialisation? Thanks in advance.

MVP 2014 Simon Posted February 20, 2013 MVP 2014 Report Share Posted February 20, 2013 Is this quite an old modem? I googled it and found a datasheet. It looks like the predecessor to the Wavecom Fastrack family. Have you tried any of the Wavecom profiles that Unitronics do support? I would start with the Fastrack M1206/1306 profile. Another handy tool is the COM sniffer, see link below: http://www.unitronics.com/Data/Uploads/Miscellaneous/Communications%20Sniffer.pdf This will show you where the communication sequence fails. If you keep hitting brick walls I would go looking for one of the modems that is on the supported list. Quote Link to comment Share on other sites More sharing options...
tss Posted February 20, 2013 Author Report Share Posted February 20, 2013 Thanks. Ultimately I just decided to send the AT commands using protocol send blocks which works well. Will need to get a more modern modem next time. Quote Link to comment Share on other sites More sharing options...
MVP 2014 Simon Posted February 20, 2013 MVP 2014 Report Share Posted February 20, 2013 I think your solution is a good one. Even though you lose some of the nice automation features of the built-in SMS, at least you have full control of the situation. Quote Link to comment Share on other sites More sharing options...
