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

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

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
