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