● Output of displacement sensor measurement data to output area
The measurement data of all tasks is automatically output from the displacement sensor to I/O port
Measurement Value of Task 1 to 4 immediately after the measured value is applied.
This enables the measurement results of all tasks to be easily handed over to the Controller.
Controller (master)
NJ-series CPU Unit
I/O ports
Output area
With EtherCAT communications, communications is performed via the I/O ports of the following four area on
the Controller. Sysmac error status area I/O ports are used only when an NJ series CPU unit is connected as
the master.
Control by control/
status signals
Data output after applica-
tion of measured value
For error status

I/O ports to which the user writes control signals to be
executed on the displacement sensor and control com-
mands
I/O ports to which the displacement sensor writes the
control signals written to the instruction area and the
result of executing control commands
I/O ports to which the displacement sensor writes the out-
put data accompanying measurement after application of
the measured value
I/O ports to which the displacement sensor writes the
error status
