Digivis connect to Variable in control buider F: Can we write value of kind REAL to variable ?
I have a question about digivis and variable in control buider F. When design HMI in digivis, and run, we can display value from variable of kind Real with Self animated Object. So can we write a radom value of kind REAL to variable?
Hope someone know that and answer for me.
Thanks for your helping.

use alphanumeric display to read and write analog value or datatype (real,integer,float) in FGR under animate menu option you can find alphanumeric display > drag and drop > goto parameterisation, in tab 'process value' enter same variable name as in tab 'General' >acion > action type 'write variable' > press F2 and select variable. Check image below, suggested to read through manual for operatior station configuration. doc no 3BDD012518
Are you asking how you can test your Graphic display?
One way is to write the variable (residing in a controller or the Emulator) from Contriol Builder in commissioning mode (which only works if the variable is not connected to an output of a function block, otherwise it will be overwritten cyclically).
Another way is to write a small program for the controller/Emulator to create a sinus wave and feed that into the variable you want to test.
In both cases you need to plausibility check the DigiVis station and download your New Graphic display to DigiVis. The Graphics Editor in CBF does not have an online mode.
Hope that helps.
