Signals definition of the RS485-Block (DB9M) of the USB/PPIM+ pin The protection circuit ensures the safe operation of the system. It’s applicable to the entire Siemens S7-200 Series PLC It’s particularly suited to the industrial scene which the communications interface is more easily damaged because of the greater interference. USB port and RS485 ports are equipped with surge protection and anti-lightning protection circuitry, which can be Hot plug. USB/PPIM+ is designed for industrial-type photoelectric isolation cable.

The two-color LED on the converter box indicates data’s transceiving status. It’s easy to extend communications distance of the RS485 without considering the power supply. This cable is 100% compatible with Siemens PPI Multi-Master USB Cable 6 ES7 901-3DB30-0XA0, and the only difference is that the work power supply from the computer's USB port through the DC / DC isolation, no longer powered by the PLC port. The cable support the 187.5 Kbps high-speed communications, and take charge of the Multiple Master Network. But the USB / PPIM + is the real USB interface cable, without installing drivers, directly use the USB option in STEP7 Micre / WIN software, support PPI, Advanced PPI,and Multiple Master Network Protocol. The cable only convert the level from USB to RS485, can only support the normal PPI Protocol. USB / PPIM + is the PPI Multi-Master programming Cable which with USB interface, to realize the level conversion and various of PPI protocol conversion from USB to RS485.Many cheap USB / PPI cable on the market simulate USB to virtual serial (COM port) to realize the communications, it’s commonly known as 'pseudo-USB interface'. Optoelectronic isolated USB Siemens S7-200PLC multi-master station PPI programming cable,directly use the STEP7 MicroWIN software to communicate,no need to install driver,support PPI,multi-master station PPI and advanced PPI,support 187.5Kbps high speed communication,just the same as 6ES7 901-3DB30-0XA0,3 meters,with communication indicator.
