6ES7 972-0CB20-0XA0,USB/MPI+V2.0:USB isolated adapter for Siemens S7-300/400 PLC
This is USB/MPI+ V2.0 only for Siemens S7-300/400 PLC.
Optoelectronic isolated USB/MPI V2.0,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.
Long-distance communications:
For USB/MPI+, the largest communication distance is up to 1000m at the communication speed of 187.5Kbps. It needs to splice 120ohm terminal resistance between 3 and 8 pin on the RS485 port(DB9 Male) to eliminate signal reflection, and connect 24VDC power between 7 and 2 pin. But requires one PFB-G for each PLC.
Please Note: USB interface cable cannot be extended.
The quality is guaranteed.It's tested before shippment.Not made by Siemens,OEM product as the replacement.
New: A brand-new, unused, unopened, undamaged item in its original packaging
