LKY2020 Posts: 21 Rating: (1)	Hi ChristophD, I'm struggling with the PC adapter USB. My OS is Win7 x64 and I've downloaded STEP7 V5.6+SP1. At the PG/PC interface I can't find the PC adapter (AUTO or MPI or PROFIBUS) option. I've tried a few drivers download and installation such as PC adapter USB A2 etc but none of them work. I've also connected the adapter 6ES7972-0CB20-0XA0 but not detected b my WIN7 OS.

If the MPI Interface connected with the Cable from the package to PLC MPI Interface and PLC is powered one? The adapter need a powersupply on the MPI Interface, only connect to USB is not enough.
