    Hello there,
    I am linking ModBus with the ModBusTCP node on the nodered control, but I could not read the values and display them on the web page. Could it be that the experience is helpful to you?

      Are you able to read modbus data in other ways?

        Yes, I can read with the DAQFactory program, but I can not transfer it to the web environment.

          If you can read data from serial port you should be able to handle it with node red

              use the serial port node, it should be in node-red (if the modbus data is coming in on the serial port of course)
