Modifying variables

The following procedure requires that the Variables pane be opened.

Updating all POUs automatically

Select Auto update of changed declarations under Extras > Options > Program options > Editors > Declaration editors to globally adopt changes made to variables in the global variable list or in POU headers. The changes will be adopted in all POU headers and POU bodies of the current project in which the variables are used. All changes take effect as soon as you save the changes in the global variable list or in the POU header.

NOTE

Global variables must be changed in the global variable list. Otherwise, auto-update has no effect.
