Thanks, It works!

[Compare tag data current vs previous scan]

I need to calculate the difference between the current tag value and its value during the previous scan.

The tag value originates from a Formula using analogue data from  a UIA-0402N Analog input and stores a Real value.

Is there a easy way to do this without using a Data Table or other FB that uses the SD card memory? 

[Link combo box to data table]

Is it possible to fill the list of an HMI Combo Box with the string data which is stored in column of a data table?

Thanks,
Marco

["Store" Ladder function does not work]

Hi,

I want to store the int16 value of an analog input into a global tag int16. The value of the input is correct but the Store Integer function does not work. The value of the global tag remains 0. I tried to find info on the subject without success. Can anyone help me?
