1. W hen the PLC is ready to recei v e
o u tp u t data, the Data O u tp u t Re qu est
Bit (DSA) is t u rned O N from the PLC
and a re qu est is made to the V ision
Sensor to o u tp u t the data.
2. The V ision Sensor o u tp u ts the data.
After the data is o u tp u t, the Data
O u tp u t Completed (GATE) signal t u rns
O N .
3. The PLC confirms that the Data
O u tp u t Completed (GATE) signal has
t u rned O N , loads the data, and t u rns
OFF the Data O u tp u t Re qu est Bit
(DSA) signal.
4. W hen the V ision Sensor detects that
the Data O u tp u t Re qu est (DSA)
signal is OFF, it a u tomatically t u rns
OFF the Data O u tp u t Completed
(GATE) signal.
* If the Data O u tp u t Re qu est Bit (DSA)
signal is not t u rned OFF w ithin the
time that is set for the retry inter v al in
the PLC Link settings, the Data O u tp u t
Completed (GATE) signal is forced
OFF and data o
u tp u t is completed.
5. The Data O u tp u t Re qu est Bit (DSA)
signal is t u rned O N from the PLC
and a re qu est is made to o u tp u t the
follo w ing data.
