USB/PPI+:optoelectronic isolated USB/PPI adapter for S7-200,replace 6ES7901-3DB30-0XA0

Product Code: USB/PPI+

Availability: In Stock

Price: $49.00


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

The working power supply of this cable is from the USB port and PLC programming interface. The two-color LED on the converter box indicates data’s transceiving status.

USB/PPI+  is optoelectronic isolated,suitable for Siemens S7-200 series PLC,especially for the strong interfere and easily damaged communication interface industry scene.The safeguard in the circuit guarantees the safely running of the system.

USB/PPI+ principle and figure structure:











Data signal B(RS485+)



Data signal A(RS485-)



24V power positive



24V power negative(RS485 logic ground)


signals definition of the RS485-Block (DB9M) of the USB/PPI+
