Hello guys!

I need help to do a backup (using prosave v15) on a tp 170A.

First: i'm using windows 7 professional

second:  i have with me two cable, and i don't know wich one to use:

USB PPI MULTIMASTER CABLE ( 6ES7 901-3DB30-0XA0) 

SIMATIC S7 ADAPTER USB (6ES7 972-0CB20-0XA0

In first image i can't select the com port because dont appear in my pc.

if i select mpi profibus, i have to add an op address according hmi.. but anyway fail..

I checked on hmi and i see dip switch but idk if i need to change it...
