Signal name Function
Control Command Turn ON this signal from the PLC to send a control com-
Execution Bit mand for the Vision Sensor to execute.
Set the control command code and parameters before
you turn ON this signal.
Turn OFF the EXE signal from the PLC when the Control
Command Completed (FLG) signal from the Vision Sen-
sor turns ON.
Execute Measure- Turn ON this signal from the PLC to send a command to
ment execute a measurement.
This signal returns to OFF when the Command Execution
Active (BUSY) signal goes ON.
Data Output Turn ON this signal from the PLC to request data output.
Request Bit When this signal turns ON, the Vision Sensor outputs
data.
* This bit can be used
only when hand-
shaking is enabled.
Turn OFF the DSA signal from the PLC when the Data
Output Completed (GATE) signal from the Vision Sensor
turns ON.
Clear Error Turn ON this signal to turn OFF the error (ERR) signal
from the Vision Sensor.
Turn OFF this signal from the PLC when the error (ERR)
signal goes OFF.
