New PC Adapter USB Now Available

  • Entry
  • Associated product(s)

The new SIMATIC PC Adapter USB connects a PC via its USB interface with the MPI/DP interface of a S7/C7 system. No slot is required in the PC, i.e. the adapter is also suitable for non-expandable PCs, such as notebooks. 

In to-day's PCs the USB port has gained more and more importance. To list the advantages of the USB port compared to the serial (RS 232) port would be superfluous here. Many notebook computers are supplied without serial port already. We are following the trend away from the serial port with the new PC Adapter USB, which will replace the PC Adapter with serial port in the medium term. 

The new PC Adapter USB can be used to program all S7-300 and S7-400 CPUs via the MPI/DP port and the S7-200 CPUs via the PPI port.

Features and new functions:

  • Automatic baud rate and profile search
  • Up to 16 communication connections, of which up to 4 can be to slaves
  • Routing supported
  • The adapter is supplied via the MPI port (24V). The previous PC adapter required a separate 5V supply.
  • The firmware of the new PC adapter can be updated at a later stage for additional functions or error corrections.
  • Compatible with USB V1.1.
  • Considerably increased performance (factor 3)
