Support Questions / Modbus 16bit addresses Read and hold value and display value in set time
« Last post by cajunman64 on February 17, 2024, 08:40:52 AM »I am working on updating my HMI project on a "BasicTrendChart" on the 2nd page with 3 Basiclabels; 2 with the same registers address; 1st Label will display the current valve and the 2nd Label will display the current valve in a set time period (say in15 minute) note: the pressure values will be live data and all the labels will be updating every second, and the 3rd Basiclabel will display the difference value between the first and second label.
I know I will have to write a code to achieve my goal but not sure when to start.
Thanks for any help
