Hello Pedro; The technical name for the "connector profibus" you show in your photograph is aRS-485 Busconnector with a piggy-back connector called a PG-socket; this allows you to connect a PG or any temporay connection, and you do not need to change the termination resistor setting. Have a look at the attached image, form the Profibus Networks manual to look at various models. Now your photograph shows both interfaces on your CPU occupied by Profibus connectors and cables. It might be that both interfaces are set to Profibus-DP communications; in that case you should try a Profibus setting in your PC/PG interface. Hope this helps, Daniel Chartier |

Hello, Yes you can connect the USB-adapter to the MPI socket. Read more about it in the USB-Adapter manual there is no risk to use the MPI port, on the profibusport with wrong settings you can disturb the Bus and CPU could go to stop. Regards, Marcjan |
