Vinicator Posted December 11, 2015 Report Share Posted December 11, 2015 My SMS Configuration shows that the modem is busy and it has the status message 7 which is modem reply error. I checked my program and it seems fine. Could anyone help? I cannot find the cause. Link to comment Share on other sites More sharing options...
s.pratt Posted December 18, 2015 Report Share Posted December 18, 2015 Hello, What modem are you using? Have you initialized it for PLC communications? Was this system working previously or is this a new project? Does the modem have a status light on it? If it has a SIM card, please ensure the service provider has given access to the network.
