The PDO mapping objects for the EtherCAT Slave Unit are listed in the following table.
Subindexes 01 hex and on give the mapped application object information.
The indexes from 1700 to 1703 hex are for receive PDO mapping objects for the EtherCAT Slave Unit.
• These objects store the RxPDO entries.
