Busy Signal Operation
The operation of the BUSY signal can be changed in the SYS/Measurement
control window.
• Set the point in processing when the BUSY signal is turned OFF. The
BUSY signal can be set to go OFF when the image input is completed,
the measurement is completed (default setting), or the display is com-
pleted.
• Set whether or not the ERR signal will be turned ON if another STEP sig-
nal is input while the Controller is still measuring.

DO Outputs the results of the expressions that were set in Do judge and DO
data.
There is a parameter in the communications settings window that allows
the user to select whether the ON signal is output when the judgement
result is OK or NG. Refer to
6HWWLQJ&RPPXQLFDWLRQV6SHFLILFDWLRQV
for details.
GATE Use the GATE signal to control the timing for the external device to read
measurement results. Set a GATE ON time that is long enough for the
external device to read the measurement results properly.
Set the output period so that the total output time is shorter than the mea-
surement interval (STEP input interval.)
Signal Function

STEP Input a measurement trigger from an external source such as a Photoelec-
tric Sensor. Synchronize the STEP signal’s rising edge (OFF-to-ON) tran-
sition and make one measurement. Keep the STEP signal ON for at least
0.5 ms.
