Raymond Santiago Posted August 3, 2013 Report Share Posted August 3, 2013 Hi, Please, I need help. I have a problem initializing modem using visilogic modem service. This is the first time I will be using modem that is not on the list of choices in preparing the modem for PLC side (I usually use enfora and siemens modem). My boss want me to use F1103 GPRS modem on our next project which is scheduled this month. I have to connect the modem to V350 but I keep on having modem initialization error when preparing the modem using the modem services of visilogic. I study a bit of AT commands and I did successfully initialized the modem on hyperterminal. Below are the instruction command I used for initialization: AT AT+CSMP=17,167,0,0 AT+CSCA? AT+CMGF=1 AT+CNMI=1,1,0,0,0 AT+CSAS I test all the settings (even "other modem") already available in the software, but as I said, none work without an error. Below is one of the code where the modem keeps on having an error: ATE0&C1&D0&S0X4Q0S0=0V1 (just one of the sample) I don't fully understand what the command does but I hope someone could help me understand what are the parameters that I should consider to successfully initialize the modem so I can use it in the PLC perfecly without having any issues or problem. Thanks in advance and hope for your response. Any idea is gladly appreciated. Best Regards, Raymond Quote Link to comment Share on other sites More sharing options...
