      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

        Hi

        Here's a screenshot of the experiment with image unipian-neuron-os-2018-06-15-beta.zip

        The same procedure, the error (maybe) the same.

          Hi Ludwigj,
          I'm sorry to say but there was a compatibility issue with the version of UniPian that you are using. If you use the version referenced in the datasheet then you should see no problem.

          UniPi have released a new Version of UniPian V1.9 today that I believe resolves the issue.

          regards David
