I/O Memory Assignment Method (PDO Mapping)
If you connect the Displacement Sensor to a CJ-series PLC, the OMRON CJ1W-NC@82 Position Control Unit
is used as the EtherCAT master. This section describes the assignments in the I/O memory of the PLC for the
Command, Response, and Data Output Areas for the Vision Sensor.
The areas for the Vision Sensor correspond to the areas for the Position Control Unit as shown in the following
table.
