Elmerazo Posted April 3, 2018 Report Share Posted April 3, 2018 Hola amigos tengo un problema con los puertos de comunicación rs485 de un plc v350. Trato de comunicar por rs485 con un plc s7-1200 de siemens, pero no funciona el puerto a pesar de haber configurado los jumpers en modo rs485, tiene una tarjeta v100-17-rs4x adicional también configurado en rs485 y tampoco funciona. Los dos puertos funcionan normal con la conexión al pc en modo serial a pesar de estar configurado en rs485. Probé este mismo programa con un v120 para descartar problemas con el puerto del v350 y el programa va bien. Por eso concluí que serían los puertos o algo de hardware. Espero me puedan ayudar, agradezco todss sus respuestas. Quote Link to comment Share on other sites More sharing options...

I try to communicate via rs485 with a siemens s7-1200 plc, but the port does not work despite having configured the jumpers in rs485 mode, it has an additional v100-17-rs4x card also configured in rs485 and it does not work either. The two ports work normally with connection to the PC in serial mode despite being configured in rs485. I tried this same program with a v120 to rule out problems with the v350 port and the program goes well. That's why I concluded that it would be the ports or some hardware. I hope you can help me, I thank you all for your answers. Quote Link to comment Share on other sites More sharing options...
