for Communications Settings
Refreshing task
period
Set the communications cycle for cyclic tag
data link communications for the Vision Sensor.
Set the same value as you set for the requested
packet interval (RPI) on the Network Configura-
tor.
• Set this parameter to the same value as you
set for the requested packet interval (RPI) in
the PLC.
• This parameter is necessary for the FQ2 to
synchronize with the communications cycles
of the cyclic tag data link communications
that are set for tag connections on the Net-
work Configurator and in the PLC.
• If the value in the FQ2 is longer than the
value in the PLC, 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 10%.
1 to 10,000 ms (default:10 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 PLC 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)
Data output period This parameter is displayed and can be set only
when [Output handshake] is set to [No]. Set the
period for outputting measurement 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)
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 measurement results.
Set the cycle time of the PLC so that it is longer
than the packet interval (RPI).
1 to 1,000 ms (default: 20 ms)
