Controlling Operation and Outputting Data with an
Ethernet Connection
● Data Output after Measurements When Handshaking Is Enabled
● Data Output after Measurements When Handshaking Is Disabled
During execution of continuous measurements, the BUSY signal remains ON. The Vision Sensor will acknowledge
the EXE signal only after the End Continuous Measurements command is executed.

After measurements are completed, the Data Output Request Bit (DSA) signal is turned ON by the PLC and a request is
made to the Vision Sensor to output the data.
(2)
The Vision Sensor outputs the data. After the data is output, the Data Output Completed (GATE) signal turns ON.
(3)
The master confirms that the Data Output Completed (GATE) signal has turned ON, loads the data, and turns OFF the
Data Output Request Bit (DSA) signal.
(4)
When the Vision Sensor detects that the Data Output Request (DSA) signal is OFF, it automatically turns OFF the Data
Output Completed (GATE) signal.
(5)
The Data Output Request Bit (DSA) signal is turned ON from the PLC and a request is made to output the data.
*1 I
f the data output request signal is not manipulated within the control timeout time (100 to 120,000 ms) in the
EtherNet/IP settings, and data output error will occur and the ERR signal will turn ON. When the ERCLR signal is turned
ON, the ERR signal will turn OFF. However, if a timeout occurs again, the ERR signal will turn ON again. Therefore,
correctly request data output (DSA control) or execute a Clear Data Output Buffer command.
*2 Indicates that the data to output is separated and output more than once.

After data output is completed, the
GATE signal turns ON and the output
data is maintained for the data output
