This section describes how objects are assigned in an EtherCAT Slave Terminal.
The following figure and table show how index numbers for objects are assigned to the EtherCAT Cou-
pler Unit and NX Units in an EtherCAT Slave Terminal.
PDO mapping objects (Input Data Mapping Objects and Output Data Mapping Objects) and application
objects (Input Data Objects and Output Data Objects) are assigned for the range of index numbers in
the table under
Assignment of Objects in an EtherCAT Slave Terminal on page A-14.
