One is MPI and can be connected to the 1st PC with baud rate up to 187.5kbps and adjust the PG/PC interface in the control panel to PC adapter (Auto) / MPI The second is DP and can be connected to the 2nd PC with baud rate upto 12Mbps and adjust the PG/PC interface in the control panel to PC adapter (Auto) / profibus And the above solution is valid only with PC adapter USB as it supports both MPI and Profibus. Here's under the Part No. and description of adapter: *6ES7972-0CB20-0XA0* 1STANN10.526ST792614064False00SIMATIC S7, PC ADAPTER USB F. CONNECTION OF S7-200/300/400 C7; WITH USB-CABLE (5M) CAN BE USED UNDER WIN 2000/XP306.00EUR With best regards,
