2 Methods for Connecting and Communicating with External Devices
(5) The PLC (user) turns OFF the Command Request (EXE) signal when the Command Completion
(FLG) signal turns ON.
(6) After detecting that the Command Request (EXE) signal has turned OFF, the Sensor Controller starts
continuous measureent and turns ON the Command Reception (ACK) signal and the BUSY signal.
(7) The Command Completion (FLG) signal is automatically turned OFF.
<Operation to End Continuous Measurement>
(8) The PLC (user) sets the End Continuous Measurements command code during execution of continu-
ous measurement by the Start Continuous Measurements command.
(9) The Command Request (EXE) signal is then turned ON and the instruction is sent to the Sensor Con-
troller.
Additional Information
Continuous measurement is not ended in the middle of measurement.
When the End Continuous Measurements command was executed, continuous measurement
is ended after the measurement in execution was completed.
<Ending Continuous Measurement>
(10) When receiving the instruction, the Sensor Controller stops continuous measurement and turns
OFF the BUSY signal.
(11) After setting the command code and response code, the Sensor Controller turns ON the Command
Completion (FLG) signal.
(12) When detecting that the Command Completion (FLG) signal turns ON, the PLC (user) turns OFF
the Command Request (EXE) signal.
(13) After detecting that the Command Request (EXE) signal has turned OFF, the Sensor Controller au-
tomatically turns OFF the Command Reception (ACK) signal and Command Completion (FLG) sig-
nal automatically.
Precautions for Correct Use
• The measurement during continuous measurement is given priority. Therefore, display of the
measurement results (total judgment, images, judgment for each processing unit in the flow
display, and detailed results) may sometimes not be updated.
• When continuous measurement is ended, the measurement results from the last measure-
ment will be displayed.
l Performing Measurement wit the STEP Signal
In addition to inputting and executing the Command Request (EXE) as a trigger, the Measurement
Trigger Execute (STEP) signal can be used to perform measurement.
