Operation to Start Continuous Measurements
1
The Start Continuous Measurements command code is set from the PLC (user).
2
The Command Request (EXE) signal is then turned ON. A request is sent to the Vision
Sensor.
3
The Sensor Controller begins preparing for continuous measurement and turns ON the
BUSY signal when the request is received.
4
The Sensor Controller sets the command code and response code when preparations
for continuous measurement have been completed.
5
The Command Completion (FLG) signal is then turned ON.
6
The PLC (user) turns OFF the Command Request (EXE) signal when the Command
Completion (FLG) signal turns ON.
7
When the Sensor Controller detects that the Command Request (EXE) signal has turned
OFF, it starts continuous measurements.
8
The Command Completion (FLG) signal and the BUSY signal are then turned OFF
automatically.
*1: A timeout error occurs and the Command Completion (FLG) signal and BUSY signal are forced OFF if the
Command Request (EXE) signal is not turned OFF from the PLC (user) within the time set in the PLC Link
settings ([Retry interval]: 0 to 999999 ms for Ethernet PLC Link, or [Timeout]: 1 to 120 s for RS-232C/422-PLC
Link).
Operation to End Continuous Measurements
9
The Stop Continuous Measurements command code is set from the PLC (user).
10
The Command Request (EXE) signal is then turned ON. A request is sent to the Sensor
Controller and continuous measurements are stopped.
Note
Continuous measurements are not ended in the middle of a measurement.
When the End Continuous Measurements command is executed, continuous measurements are ended after the
measurement that is currently being executed is completed.
• Ending Continuous Measurements
11
The Sensor Controller sets the command code and response code when continuous
measurement is stopped.
12
The Command Completion (FLG) signal is then turned ON.
13
The PLC (user) turns OFF the Command Request (EXE) signal when the Command
Completion (FLG) signal turns ON.
14
When the Sensor Controller detects that the Command Request (EXE) signal is OFF, it
automatically turns OFF the Command Completion (FLG) signal.
IMPORTANT
• The measurements during continuous measurements are given priority. Therefore, display of the measurement
results (overall judgment, images, judgment for each processing unit in the flow display, and detailed results) may
sometimes not be updated.
• When continuous measurements are ended, the measurement results from the last measurement will be
displayed.
