Set whether to provide an interlock with the PLC when per-
forming data output.
• None None: Data is output regardless of the status of signals from
• [Handshaking] the PLC. GATE is always OFF.
Handshaking: Data is output after confirming DSA from the
PLC.
Selected: Measurement processing and data output process-
ing are performed in parallel.
The data output processing does not affect the processing time
of the measurement flow.
• Selected.
• [Not selected.]
Not selected: Measurement processing and data output process-
ing are synchronized so that all data output processing is finished
when measurements are finished.
This increases the overall processing time of the measurement
flow.

Description
IMPORTANT
Always set the output control to [Handshaking] for
asynchronous output. If you set the output control to
[None], operation will be fixed at the following values:
Output time: 100 ms, Output period: 200 ms.
If you need a shorter output time and output period when
the output control is set to [None], do not select
asynchronous output.
Note
This is the same as the PLC Link operation of the FZ4
Vision Sensor.
