8-6-5 Controlling BOOL Variables, Changing Present Values, and Using
Forced Refreshing
Right-click the variable name to delete in the Watch Tab Page and select Delete from the menu. Or,
press the Delete Key to delete the variable name directly.
The variable name and the row it was displayed on are deleted.
You can debug the safety program by controlling BOOL variables (Set/Reset), changing present val-
ues, and executing forced refreshing from the Sysmac Studio.
This function allows you to change the values of BOOL variables in the FBD editor or Watch Tab Page
to debug safety programs.
Controlling BOOL Variables in the FBD Editor (Set/Reset)
1 Click the present value for the BOOL variable to change.
Example: To set variable a, click the present value of FALSE.
The value changes to a temporary status.
A light blue triangle is displayed at the lower left of the value. This indicates that a temporary
TRUE/FALSE value is in effect.
Each click toggles the temporary value through Present Value − TRUE − FALSE − Present
Value.
