The light-emitting diode on the conversion box indicates the status of data transmission and reception.ĦES7901-3DB30-0XA0 can communicate with S7-200PLC and also supports communication with Siemens touch screen. It is easy to extend the communication distance of the RS485 terminal without considering the power supply. The difference is that the working power source is taken from the USB port of the computer and is powered by DC/DC isolation. This cable is 100% compatible with the original Siemens USB multi-master cable 6ES7 901-3DB30-0XA0. And USB/PPIM+ is a real USB interface cable, no need to install a driver, directly use the USB option in STEP7 Micro/WIN software, support PPI, advanced PPI (Advanced PPI), multi-master PPI (Multiple Master Network) protocol, Support 187.5Kbps high-speed communication, and can hold tokens in multi-master PPI network. This kind of cable is only a level conversion from USB to RS485 and can only support ordinary PPI protocol. At present, many cheap USB/PPI on the market communicate by converting USB into the virtual serial port (COM port), commonly known as a “pseudo-USB interface”. Siemens s7-200plc multi-master ppi programming cable with isolated USB interface, directly use the usb interface in step7microwin software, no need to install drivers, support ppi, multi-master ppi, advanced ppi protocol, support 187.5 kbps high-speed communication, with communication indicator.ĦES7901-3DB30-0XA0 is an intelligent multi-master PPI programming cable (PPI Multi-Master Cable) with a USB interface, which realizes level conversion from USB to RS485 and various PPI protocol conversions.
