Basic Operation
Measurement Mode and Measurement Start Timing
The procedure for specifying the measurement start timing can be selected from the following three modes.
Use these modes to synchronize the measurement timing between sensors or to perform synchronization
control
with a servomotor or other external devices.

• Measures one by one input the external Trigger signal in External synchronous measurement mode.
• Need to input the external Trigger signal depending on the setting content of the filtering process
.
Example)
When you set the Average number to 128, need the external Trigger signal to input 128 counts.
• When you set the Exposure control mode to Auto, multiple inputs of e
xter
nal Trigger signal are necessary after
adjusting the measurement object within the measurement range for optimization of exposure status.
• The following items use parameters from External/PDO synchronous measurement
mode, or outside of the Internal
synchronous measurement mode so separate settings by mode is possible.

mode
Internal synchronous
measurement mode (initial
value)
The measurement start timing is automatically determined
according to the set measurement cycle intervals.
Use this mode to perform measurements cont
inuously with a sensor
only or to shorten the measurement cycle as much as possible.
External synchronous
measurement
T
he measurement start timing is specified by TRIG input signals.
Use this mode to perform measurements in synchronization with
external signals from parallel I/O.
One measurement is performed for each TRIG input signal. In the 2
area mode
, measurements for 2 areas are performed continuously.
PDO synchronized mode The measurement start timing is determined by Sync0 signals*
automatically se
nt from the EtherCAT master. Use this mode to
perform measurements by synchronizing the EtherCAT slave and
EtherCAT master slave.
