Transitions
Transitions can be executed or stopped forcibly, by force-setting/force-resetting, as
long as the PLC is not in the RUN mode.
Force-setting turns a transition flag ON, and force-resetting turns a transition flag OFF.
The ON/OFF status will be maintained until the forced status is cleared, or until another
force-set/force-reset operation is performed. It will not be changed by external inputs or
by program execution results.
Force-Setting/Force-Resetting a Transition
1 In the SFC editor, select and right-click the transition to force-set/force-reset.
2 Select

The transition will be marked to indicate that it has been force-set/force-reset, as
shown below.

Force-resetting Transitions
If the Transition Flag following a step that became active when step status changes is
force-set, the step status will immediately change again and the actions will not be
executed. Unless you want to force the status of the previous step to change when you
force-set a Transition Flag, always cancel the force-set status in advance.
