The two-color LED on the converter box indicates the data transmission and reception status. The working power is taken from the USB port and is not powered by the programming port of the PLC. The driver control running in the computer simulates the USB interface of the computer into a traditional serial port (commonly known as the COM port), thereby using various existing programming software, communication software, and monitoring software. It is a programming cable that provides serial connection and RS485 signal conversion and PPI protocol conversion via USB interface. USB/PPI cable is suitable for the Siemens S7-200 full range of PLCs.
