for Communications Settings
Changes to settings are not applied until the Vision Sensor is restarted. Therefore, save the settings and then restart
the Vision Sensor.

Setting the Data to Output Automatically after Measurements
You can set in advance the data to output automatically after measurements. (You can set up to 32 data items.)
Data That Can Be Output
• Data Output
On the FQ2, data that is output after measurement can be assigned to Data 0 to Data 31 in the output data
settings.
When an item is assigned to an output data setting, the data is output in units of four bytes per item.
The maximum data size that can be output at once is 1,024 bytes.
Retry interval Sets the interval for retrying communications.
This setting is enabled only when [Retry details] is set to [ON].
0 to 2,147,483,647 ms
Default:10,000 ms
Max output data Sets the maximum data size that can be output at one time
through PLC Link communications. Set the number of bytes. Any
output data that is beyond this value is discarded.
32 to 1,024 bytes
Default: 256 bytes
Data output period This parameter is displayed and can be set only when [Output
handshake] is set to [No]. Set the period for outputting measure-
ment results.
Set a value that is longer that the GATE ON output time and
shorter than the measurement interval of the Sensor.
2 to 5,000 ms (default: 40 ms)
Connection mode Sets the TCP connection mode. TCP server or TCP client
Default: TCP server
GATE signal ON
period
This parameter is displayed and can be set only when [Output
handshake] is set to [No].
Set the time to turn ON the GATE signal.
Set the time that is required for the PLC to read the measure-
ment results.
Set a time that is longer than the PLC cycle time.
1 to 1,000 ms (default: 20 ms)
If multiple inspection results are assigned to one output data setting, that output data setting will be set for more than
four bytes of data output. As a result, it is possible that an item that exceeds the data size that can be output at once
will be set in the data output setting. In this case, the data that exceeds the data size will be discarded.
