The value of a variable can be changed while you are in Online mode when monitoring is active. Depending on whether the variable is Boolean or non-Boolean, the procedure of setting the new value varies.
- Open the Change value dialog
- ST editor: Press <Ctrl> and click the variable name.
- LD/FBD editor, IL editor: Double-click the variable name or press the space key twice while the mouse is over the variable name.
- SFC editor: Double-click the variable name.
- Select a new value
- For Boolean variables, select the new value from one of the following options:
Invert: The value of the Boolean variable is inverted. For example, if the variable has the value TRUE, it is set to the value FALSE.
TRUE: The Boolean variable is set to the value TRUE.
FALSE: The Boolean variable is set to the value FALSE.
- For non-Boolean variables, enter the new value in the dialog window that appears and select OK.
