    Thanks for your helpful information. It helps a lot for my modbus project with multiple registers conversion to float.

    Hello Geeky-Gizmo-Guffaws, 5.5.2024 calling from Germany. Thank you very much for your Video. I was looking for a long Time to convert/read as a Human the readings from a CINT DTSI666 over Modbus. Now i got it, so many thanks. Sincerly Konrad

    Hello. I have a qeustion about using this lib.
    When I disconnect (physically) slave device from hardware where Node-red server runs, whole Node-red server goes down. In console window I see next message: "Error: Writing to COM port (GetOverlappedResult): Operation aborted". To solve this problem I should restart Node-red server. What wrong I do? Any ideas?

    Very good video ...
    But what can we do if we want to write a float 32 bits from node red to a real Modbus server (PLC for example)?
    How can we save them inside the PLC in two 16-bits registers?
    Thanks in advance

    Worked great for reading iSMA modes TCP modules. No I just need at guide to write to it.

    how to split
    words into 2 bytes

    • @automationcontrolhub
      @automationcontrolhub  7 месяцев назад

      You can use bit shift operation in javascript, something like:
      data[0] = (byte) (number & 0xFF);
      data[1] = (byte) ((number >> 8) & 0xFF);

    • @automationcontrolhub

      Yes it can, but it required ieee754 double floating package to convert 64bit modbus data

    Hello,
    I want to set the parameters of an industrial drive using a node through RS485 serial communication.
    In this project, I need to use the hex codes of an industrial drive and control the drive using the hex codes.
    Can anyone help me with this project?

    • @automationcontrolhub
      @automationcontrolhub  7 месяцев назад

      Hi, yes you can do it using Hex to decimal pallette on node red.
