  • UDP Profibus-Modbus coupler

    UDP Profibus-Modbus coupler Data transmission & Communication

    The UDP PROFIBUS-MODBUS coupler converts the MODBUS RTU telegram data into PROFIBUS DP telegrams. The coupler thus acts as a slave on the Profibus. MODBUS interface configuration via GSD file

    • Configurable for any serial protocol
    • Serial data rate configurable up to 57,600 baud
    • Full duplex
    • Diagnosis options via PROFIBUS


    PROFIBUS specification

    • 93.75 kbaud PROFIBUS FSK
    • PROFIBUS address can be set via rotary switch
    • 27 byte extended diagnosis
    • Up to 244 input and output bytes
    • Supports 'Sync' and 'Freeze'


    Modbus specification

    • Master or slave
    • Up to 20 MODBUS slaves can be queried
    • Data format RTU or ASCII
    • Implemented MODBUS functions: 1, 2, 3, 4, 5, 6,7, 15, 16, 23
    • 600 to 57,600 baud
    • 7 or 8 data bits


    Supply voltage
