No Output Control
The Controller outputs measurement results to the external device without
synchronizing communications. Monitor the Controller’s GATE signal from the
external device and read the measurement results at the external device while
the Controller’s GATE signal is ON.

BUSY
Indicates that the Controller is performing an operation such as measuring
or switching scenes. Do not input the next command while the BUSY sig-
nal is ON. If another command is input while the BUSY signal is ON, either
the operation being performed or the command that was input may not be
properly executed.
When the BUSY signal’s OFF timing is changed to Image Input Com-
pleted, the Controller will continue measuring even though the BUSY sig-
nal is OFF. Do not input the next command until the measurement is
completed. Refer to the
6(&7,216\VWHP6HWWLQJV
for more details.
OR
Outputs the overall judgement.
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.
