Fixed PDO Mapping

The tables below show the details of fixed PDO mapping for GX-series EtherCAT Slave Units.
Note that it is not possible to change fixed PDO details.
 PDO mapping for Digital I/O Slave Unit
Fixed PDO mapping of a Digital I/O Slave Unit is determined by the number of inputs and/or outputs
per Unit and whether or not Expansion Units are connected.
