In this example, three PDO mapping objects (PDO A, PDO B, and PDO D) are allocated to index
1C13 hex (for TxPDOs).
Similarly, a PDO (for the RxPDO) is assigned to the index 1C12 hex.
These assignments determine the PDOs to use for communications between the EtherCAT master
and slave.
 Allocating PDOs to the IO-Link Master Unit
The IO-Link Master Unit has the following PDO mapping objects.
• An object that can be allocated to the Sync Manager
• An object that is fixed for the allocation to the Sync Manager
In the IO-Link Master Unit, PDOs are allocated by default (factory setting). These PDOs determine
both the RxPDOs and TxPDOs that are used for communications with the EtherCAT master.
For the PDO mapping object that can be allocated to the Sync Manager, you can change the allo-
cation from the default value.
Refer to A-1-5 PDO Mapping Objects on page A-10 for details on the PDO allocation method to
the IO-Link Master Unit and PDO mapping objects.

Service Data Objects (SDOs)

This section describes the service data objects that are supported by the IO-Link Master Unit.
Introduction
IO-Link Master Units support SDO communications.
The EtherCAT master can read and write data from and to entries in the object dictionary with SDO
communications to make parameter settings and monitor status.
Refer to A-1 CoE Objects on page A-2 for the objects that you can use with SDO communications.
