Siemens S7-200PLC programming cable with USB interface, USB/PPI , 3 m, with communication indicator.
USB/PPI is the programming cable in which USB interface provided the serial connection, RS232 signal conversion and PPI protocol conversion. Under the control of computer-driven driver, the programming cable makes it possible for the computer's USB interface to simulate the traditional serial (known as COM interface), thus various existing programming software such as communications software, monitoring software and other applications can be normally used. The working power supply of this cable is directly from the USB port, but not the PLC programming interface. The two-color LED on the converter box indicates datas transceiving status.
USB/PPI is applicable to the S7-200 series of Siemens PLC. For the industrial scene which the communications interface is more easily damaged, the photoelectric isolation USB / PPI + programming cable is the choice.

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: blackUsage:
USB device drivers should be installed before using USB/MPI+ programming cable, which are available on the CD-ROM sold together with the cable. And for the specific installation steps, please refer to the instruction files on the CD-ROM drivers, and details are not necessarily listed here.
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", its 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!
