Note
To execute a measurement trigger after changing the scene, first confirm that the Command Completion (FLG)
signal and the BUSY signal that turned ON for execution of the Select Scene command have turned OFF.
Also, if the BUSY signal is ON for too little time and the external device cannot read it, increase the time that the
BUSY signal is ON for changing scenes so that the external device can read the ON state. To do this, change the
[Add time] setting for the [Scene switch time]. Refer to
during Measurement in the Vision System FH/FZ5 Series User's Manual (Cat. No. Z365).

When the Sensor Controller detects that the Command Request (EXE) signal is OFF, it
automatically turns OFF the Command Completion (FLG) signal and the BUSY signal.
