Termination of the force mode
The force mode can be terminated in the following ways:
 manually through the user
 automatically after the defined time delay
 automatically after 30 seconds if the MELSEC-WS safety controller detects an error
(e.g. if the connection to the PC is interrupted)
When the force mode is terminated, the safety controller switches all outputs to Low
and the active application is stopped.
Ensure that no dangerous situation can occur when the force mode is
terminated!

Ensure that your machine or system is transferred to a safe state and can not be
damaged when the force mode is terminated.
 While the force mode has been active, the actual value of an input may have
changed (e.g. button pressed, safety door opened etc.). Ensure that this can not
cause any dangerous situation before restarting your machine or system.
 Click on the Stop force mode button. A safety message will appear. Click on Yes
to confirm and terminate the force mode or click on No to keep the force mode
active.

If no force action (e.g. forcing of an input) has occurred for the time defined when
the force mode was started, the force mode will be automatically terminated. During
force mode, a timer in the top right corner shows the time remaining until the force
mode is automatically terminated. Each action resets this timer. You can also reset
the timer using the
Trigger force mode button on its left. 15 seconds before the
timer expires, a dialog is displayed that reminds you of the imminent termination of
the force mode.
 If you ignore this dialog, the force mode will be terminated after the defined time
delay has expired.
Or :
 Click on Cancel . The dialog will close and the force mode will be terminated after
the defined time delay has expired.
Or :
 Click OK in order to close the dialog, reset the timer and keep the force mode active.
