TRND Graph in HMI



  • Hi All,

    Is it possible to combine several TRND blocks in to one graph? I have four TRND blocks logging and would like the HMI to display all data in one graph not four.

    Cheers

    Mike



  • Hi Mike,

    you can use function block called TRNDV. To combine the signals from all four TRND blocks use block RTOV.

    If you need any help, let me know.

  • Hi Tomas,

    Thank you, that looks like exactly what I need. Does the TRNDV block still work in the same with the TRND HMI component? Can you label each individual data stream etc.

    Cheers

    Mike



  • Hi Mike,

    yes, you can combine the TRNDV with TRND HMI component in the same way as with classic TRND. All settings should be also available.

    Cheers,
    Tomas
