USB/PPI:programming cable for S7-200PLC

USB/PPI interface,programming cable for Siemens S7-200PLC ,3 meters,with communication indicator,can replace 6ES7 901-3DB30-0XA0,the largest communication distance of up to 2 kilometers.Not support multi-master station

Not isolated,so it doesn't support hot plug,if need isolated cable,pls choose USB/PPI+,you can click the following website for USB/PPI+:


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 of this cable is from USB port,not provided by the communication port of PLC.The LED of the adapter indicates the sending and receiving status of data.
USB/PPI is applied to Siemens S7-200 PLC,NOT support hot plug.For the industry scene of strong interference and easily destroying communication port,pls choose optoelectronic isolated USB/PPI+ programming cable.

Outline configuration:

Features and technological index:

● Support USB/PPI operating system: Windows2000/XP (WinNT4/95/98/Me/DOS not included ) 
● Support USB/PPI programming software version: STEP7 Micro / WIN V3.2 and above. 
● Fully compatible with USB V1.1 norms and USB CDC V1.1 
● USB-bus powered, with current consumption is 50 mA 
● Baud rate: 300 bps ~ 1Mbps automatically adapt to the standard baud rate 
● Support UART data format: data bits: 7-8; stop bit: 1, 2; check-bit: odd / even / no parity 
● Support long-distance communications, the largest communications is two kilometers (9600 bps) 
● Each PC only supports one USB cable programming 
● Working temperature: -20 ~ +75 ℃ 
● Cable length: 3m; Color: black


 USB device drivers should be installed before using USB/PPI programming cable.    After completing Driver installation, the corresponding COM port for the USB/PPI  programming cable will be displayed in the “Device Manager” of Window. The step next is just to choose this COM port in the programming software and other application software and keep other communication parameters as in the Default settings. And the following steps are exactly the same as in the traditional programming cables with RS232 interfaces. Here are requested to indicate that "USB" option in the local communications interface setting which the software is not support to the programming cable.

    If the COM port in the programming software with "*" symbols, such as "* COM3", it’s shown that the COM port have faults. Quit the software and plug a USB plug or re-install the USB driver.

    This cable do not support the 187.5 Kbps baud rate as the same with the Siemens PC / PPI programming cable which with the RS232 interfaces.

    Please note that Siemens COM port in programming software is up to support the option to COM8.But the ports more than COM8 are able to choose but in fact can not be used!

Long-distance communication:

    The largest communications range between the USB/PPI and PLC are up to 2 kilometers (9600 bps),when external plus terminals 120 ohm resistance is needed to connect between the pin3 and pin8 of the RS485 ports (DB9 Male) to eliminate signal reflection. And a PFB-G Bus Isolators is needed to install at the end of PLC. 0.22 mm2 or more unshielded twisted pair lines are used for Communications. When the distance is Over 2,000m, a RS485 repeaters (model: E485GP), can be installed for extending the distance.
