Outputting Data and Controlling Operation through PROFINET
146
FQ2-S/CH User’s Manual
for Communications Settings
Parameter Description Setting range
Output handshake Set whether to synchronize with the external
device when data is output.
No: Measurement results are output without
synchronizing with the external device.
Data Output after Measurements
When Handshaking Is Disabled: p. 117
Yes: Measurement results are output while syn-
chronizing with the external device.
Data Output after Measurements
When Handshaking Is Enabled: p. 117
•Yes
•No
(default: Yes)
Output data size Set the size of the data that is to be output as
the measurement result.
Any changes in the setting are applied when
the Sensor is restarted.
Order of Output of Measurement Data
and Characters: p. 24
Set the same value as the parameters set in the
external device.
32 bytes, 64 bytes, 128 bytes, or 256 bytes
(default: 32 bytes)
Refreshing task
period
Set the communications cycle for PROFINET
IO communications for the Vision Sensor.
• Set this parameter to the same value as you
set for the requested packet interval (RPI) in
the external device.
• This parameter is necessary for the FQ2 to cycle
at the update cycle set in the Engineering Tool.
• If the value in the FQ2 is longer than the
value in the external device, cyclic data
exchange will not be performed according to
the expected communications cycle.
• The smaller the setting of this parameter is,
the more the measurement processing time
will be affected. For the lowest setting of
1 ms, the processing time will increase by
approximately 5% to 20%.
1 to 10,000 ms (default: 16 ms)
Timeout This parameter is displayed and can be set only
when [Output handshake] is set to [Yes].
A timeout error will occur if there is no response
from the external device within the time that is set.
• From when measurements are completed
until the DSA Bit turns ON
• From when the GATE flag turns ON until the
DSA Bit turns OFF
• From when the GATE flag turns OFF until the
DSA Bit turns ON
0.1 to 120.0 s (default: 10.0 s)
If the total size of the data that is specified as
output data exceeds the size that is set here, all
of the data will not be output at the same time,
but will be separated over more than one cycle.
