The USB programming cable is a programming cable that uses a USB interface to achieve serial connection and peripheral port signal conversion. This cable programs through a USB interface connector and a serial peripheral signal converter. Under the control of the computer, it simulates the computer's USB interface as a traditional serial port (commonly known as a COM port), allowing the use of existing programming software, communication software, and monitoring software. The cable's power supply comes from the USB port and the programming port of the LOGO controller. The USB-LOGO cable uses opto-isolation technology and is suitable for LOGO controllers, especially in industrial environments with high interference and where communication ports are easily damaged. Various protection measures in the circuit ensure safe system operation. The USB-LOGO cable abandons the bulky adapter design of the first generation, adopting a new design with a built-in high-speed communication micro-integrated chip and a 6-pin square port on the side. It is more portable and offers more stable and powerful functionality. Application: Suitable for Siemens LOGO series PLC programming cables.
