(hibernate mode). Function The SIMATIC PC Adapter USB connects a PC to the MPI/DP interface of an S7/M7/C7 system via USB. A slot is not required in the PC, which means that the adapter can also be used for non-expandable PCs such as notebooks.
Properties of the PC Adapter USB Performance specifications The PC Adapter USB can be used on MPI and PROFIBUS networks. Starting at firmware V1.1, the PC Adapter USB can also be operated on homogeneous PPI networks. The following table shows the transmission rates and network types supported by the PC Adapter USB.
MPI cable (0.3 m) A5E00164946 You can forward your spare parts orders to your local Siemens partner. Supplies (not included in the PC Adapter USB) To operate the PC Adapter USB to MPI/DP interfaces which do not have a 24V supply voltage, you can order an external power supply (order number: 6ES7 972-0CA00-0XA0).
