Offsetting the Timing of Outputting Measurement Results
The measurement result is output when the TRIG signal turns ON the number of times set for the [Number of
delay] parameter.
This allows you to delay the output timing of the measurement result from the Sensor according to the actual
processing timing of the line.
Example: Sequential Feed Line That Uses a Star Wheel
In a line like this, you can synchronize the output timing of the measurement results and the discharge timing of
NG products that are detected.
If you set the [Number of delay] parameter to 4, the measurement result output is delayed by four TRIG signals.
• With synchronized output, the number of times that the TRIG signal turns ON is counted. Therefore, use synchro-
nized output only when only one measurement result is output for each measurement. (Output either the parallel
judgement or data.)
• Use a measurement trigger only for single measurements.
If you perform continuous measurements by inputting a command, the output timing will not be correct and the
Sensor may malfunction.
