Measurement Mode And Measurement Start Timing - Omron ZW-7000 Series User Manual

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.

Important
• 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 external 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.

Setting value Description
Internal synchronous The measurement start timing is automatically determined
measurement mode (initial according to the set measurement cycle intervals.
value) Use this mode to perform measurements continuously with a sensor
only or to shorten the measurement cycle as much as possible.
External synchronous The measurement start timing is specified by TRIG input signals.
measurement 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 sent from the EtherCAT master. Use this mode to
perform measurements by synchronizing the EtherCAT slave and
EtherCAT master slave.
