Specification :

optoelectronic isolated USB/MPI,Siemens S7-300/400 PLC Programming adapter cable,3 meters,with communication indicator,can replace Siemens 6ES7 972-0CB20-0XA0,automatically adjust the communication speed from 19.2Kbps to 115.2Kbps for the PC port,automatically adjust the communication speed from 19.2Kbps to 187.5Kbps for the MPI interface.It doesn't support profibus function.

USB/MPI+ is the optoelectronic isolated adapter for industrial design. There is anti-surging& anti-lightning protection circuit for the USB and RS485 interface. It support hot plug. It’s suitable for the communication between Siemens S7-300/400 series PLC or other equipments with MPI interface and computer. In particular, it applies to the strong interfere industrial scene and the safeguard in the circuit guarantees the safely running of the system.

USB/MPI+ programming cable simulate USB port as traditional serial port (usually COM3), which enables existing programming software(STEP 7) to communicate through simulated traditional port and PLC devices.
