Profibus or MPI

[denise01]

Hello, I have a S7 313 CPU connected to a TP170B via MPI. I have just ordered and recieved a 6ES7-972-0BB12 0XAO Lead so that I can plug in my Laptop and monitor programme without disturbing the HMI connection. The lead is Profibus connection ie two wires A1 and B1 and my existing CPU-TP170B is four wire pins 3,4,5 and 8. is it possible to use two wires for MPI or is there a special Lead that I would need to get. I only need to connect one Screen so would Profibus be okay for connection. Regards Peter
