Sample Ladder Programming

● Command/Response Communications
The following sample program is used to clear measurement values.
The Clear Measurement Values command (lower bytes: #2010, upper bytes: #0010) is sent to the Vision
Sensor.

Important
Create the ladder program to control the TRIG signal so that it does not turn ON while the BUSY signal is ON.
If not, a TRIG input error will occur and the ERROR signal will turn ON.
Note
While the trigger input (TRIG signal) for parallel measurements is ON, the EtherNet/IP BUSY signal will also be ON.
Therefore, no EtherNet/IP commands will be executed. Any EtherNet/IP commands will be executed after execution
of the parallel commands. You can also use a EtherNet/IP to perform measurements and output data with the paral-
lel I/O measurement trigger signal (TRIG).
