l Continuous Measurement Command (Without handshaking)
Continuous execution is used to repeatedly execute measurement by starting the next measure-
ment operation (image input and measurement processing) as soon as single measurement opera-
tion (image input and measurement processing) is completed.
Continuous measurement is started when the Start Continuous Measurements command is exe-
cuted and ended when the End Continuous Measurements command is executed.

(2) After checking that the BUSY signal and the Command Completion (FLG) signal have turned OFF, the
PLC turns ON the Command Request (EXE) signal again to instruct the Sensor Controller to perform
it.
(3) When completing the preparations for continuous measurement, the Sensor Controller sets the com-
mand code and response code. when preparations for continuous measurement have been complet-
ed.
(4) The Command Completion (FLG) signal is turned ON.
