Modem with FX2N

[maccxim 0]

I need to connect US Robotics 56K modem with FX2N plc using FX2N-232BD. Anybody know the AT commands to setting modems on pc side (same US Robotics) and on plc side? I have to use only Melsec Medoc to communicate. Best regards Max

Hi Max, Here is the European Telecom Standard list of AT commands. I downloaded this a while ago when I was researching the communication to a gsm modem. Good luck. etsi0707.pdf

Thank you for your .pdf. But your documentation is about GSM modem. I have an analog modem. Max

Hello, You can try the following init-strings: Modem connected to PC: AT&F&D0&K0&W Answering modem - connected to FX-system: AT&F&D0&K0Q1E0S0=1&C1&W I've tested these strings when using PowerBit-, Westermo- and SixNet-modems and they have worked fine every time! I hope that you can connect to the PLC using the above mentioned strings, if you have more questions don't hesitate to ask, I've worked a lot with modems. /sirPLC
