2 Command/Response Method (Refer to Command/Response Method: p.20)
Control is performed by storing the control command and the response to that command in the I/O mem-
ory of a PLC.
This method is best suited to send multiple commands to the Sensor without using PLC communications
instructions.
3 Data Output after Measurements (Refer to Data Output after Measurements: p.21)
After a measurement is executed, the measurement data specified for output is automatically output to
the specified words in the I/O memory of the PLC.
This is suited to reception of the measurement result data of each inspection item.
