10
The BUSY signal turns off and the Command Completion (FLG) signal turns ON when
the measurement processing is completed.
11
The PLC (user) turns OFF the Command Request (EXE) signal when the Command
Completion (FLG) signal turns ON.
12
The Sensor Controller confirms that the Command Request (EXE) signal is OFF and
automatically turns OFF the Command Completion (FLG) signal.
Note
Saving All of the Measurement Results
If you output data from more than one Data Output Unit or for repeatedly measured output data (e.g., for continuous
measurements), the same Data Output Area will be overwritten.
To save all of the output data, adjust the output period and output time that are set in the EtherNet/IP settings so that all of
the output data is output and either receive all of the output data by using the Result Completion (GATE) signal or use
handshaking control.
Handshaking lets you control data output by using the GATE signal turning ON as a trigger for the data output timing and
turning ON the DSA to read the output data. (This is necessary from the second output data item onward.)
Each time that data is output, read the output data and move it to a different part of I/O memory in the PLC.
Refer to Data Output Control with Handshaking (p.32) for details on handshaking.
You can compare the received number of output data and the number of measurements for continuous measurements to
check if all of the measurement results have been received.
Use the following method to check the number of measurements that was actually executed.
• Application Example
Set a calculation to count the number of measurements that are executed in the measurement flow.
If you set something like [DO+1], each time a measurement is executed (each time the measurement flow is executed),
1 will be added to DO, so the present value of DO will give you the actual number of measurements.
