1
The measurement command code and command parameters are set from the PLC.

Next, confirm that the BUSY signal and the Command Completion (FLG) signal have
turned OFF and then turn ON the Command Request (EXE) signal again. A request is
sent to the Sensor Controller.
3
The Sensor Controller executes measurement processing and turns ON the BUSY
signal when the request is received.
4
When the first Fieldbus Data Output Unit in the measurement flow is executed, the
Sensor Controller outputs the output data for the first Fieldbus Data Output Unit to the
Data Output Area.
5
The Sensor Controller turns ON the Result Completion (GATE) signal when it has
output the output data to the Data Output Area.
6
The Sensor Controller turns OFF the Result Completion (GATE) signal after the output
time set in the EtherNet/IP settings has elapsed.
7
The second Fieldbus Data Output Unit in the measurement flow is executed.
8
When the time that is set for the output period in the EtherNet/IP settings has elapsed,
the Sensor Controller outputs the output data for the second Fieldbus Data Output Unit
to the Data Output Area.
The data for the first Fieldbus Data Output Unit is overwritten at that time.
9
The Sensor Controller turns ON the Result Completion (GATE) signal and then turns it
OFF after the output time that is set in the EtherNet/IP settings has elapsed.

*1: A timeout error will occur if you do not turn off the Command Execution (EXE) signal from Sensor Control-
ler (master) within 10 seconds. Then Command Completion (FLG) signal and Busy (BUSY) signal will be
forced to turn off.
*2: Busy (BUSY) signal is automatically switched ON to OFF when the command execution is completed.
