  Be sure that the I/O outputs change during error, or at Emergency Stop or Safety Door Open when designing the system.

• Error Handling

  As this program, finish the task promptly after completing the error handling.

• Outputs OFF during Emergency Stop

  As this program example, when the task executes I/O On/Off after the Emergency Stop, uncheck the [Setup]-[System Configuration]-[Controller]-[Preferences]-[Outputs off during emergency stop] check box. If this check box is checked, the execution order of turn Off by the controller and turn On using the task are not guaranteed.
