Why are the values of some resources overwritten by the HMI Editor?

FAQ #101629

 

Reason
In an earlier version of the HMI Editor it was possible to give an initial value to the resources using the following window (2x click on the symbol) in the HMI Editor. This value is written in the resource when the CPU goes in RUN!

Now it isn't any longer possible to modify those global symbol inside the HMI Editor because this practice prooved to be confusing and created more probelms than it solved.

Solution
In order to delete the HMI initialisation of the ressource in the HMI Editor the following work around is needed;

• create a new HMI Editor file in another empty CPU
• import the HMI Project into this new one; Menu (in the new HMI file): File/Import (click: select all + Ok)
• open the window above in the Object Attribut / Ressource with 2 x click on the ressource
• delete the initialisation, click: ok
• save and compile the HMI file
• import this modified HMI file into the original CPU; Menu: File/Import (click: select all + Ok)
