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.
