CODESYS to Neuron comm problem

  • Hi
    I have a problem with running modbus communication between CODESYS and Neuron S103.
    I performed the installation according to the instructions on the web CoDeSys. The screenshot shows an unipi_modbus_server error message.
    I tested the last unipian image, and mervis OS image.
    Please tell me where I'm making a mistake.

                                                                        thank you
