Interface type: The Profibus interface usually uses an RS485 serial port, and generally uses a SUB-D female interface. The pin definition and connection mode of the PROFIBUS interface are similar to that of a standard RS485 interface.

Features and performance: Profibus cable connectors support a wide range of baud rates, from 9.6Kbit/s to 12Mbit/s. It supports single-master or multi-master systems, and provides cyclic user data transfer, dynamic activation, configuration check, powerful diagnostic functions and other functions. In addition, the Profibus cable connector also has reliability and protection mechanisms, such as the transmission of all information according to the hamming distance HD=4, the DP slave station with Watchdog Timer (Watchdog Timer), the input/output of the DP slave station access protection.
