In the previous example, a single application object is assigned to the PDO at index 1BFF hex (name:
512th transmit PDO mapping). This PDO is a TxPDO. The application object contains the Sysmac error
status at index 2001 hex and subindex 01 hex.
 PDO Mapping When You Use Sysmac Studio with the Built-in EtherCAT Port
on an NJ-series CPU Unit
When you use Sysmac Studio with the built-in EtherCAT port on an NJ-series CPU Unit, a PDO
mapping object is called an I/O entry mapping. The application object is called an I/O entry, and it is
referenced by NX objects.
You can add or delete I/O entries for some I/O entry mappings but not for others.
Default I/O entries are mapped to the I/O entry mappings that allow the addition or deletion of I/O
entries. For Units with I/O entry mappings that allow the addition or deletion of I/O entries, you can
use the Sysmac Studio to change the default I/O entry mappings.
To change I/O entry mappings for EtherCAT Slave Terminals on the Sysmac Studio, use the I/O allo-
cation settings on the Edit Slave Terminal Configuration Tab Page. Refer to 9-2-4 I/O Allocation
Information on page 9-13 for information on editing I/O allocation settings.
Refer to 9-2-4 I/O Allocation Information on page 9-13 for details on assigning I/O entry mappings
for the EtherCAT Coupler Unit.
Refer to the user's manual for the specific NX Units for details on I/O entry mappings.
Additional Information
Refer to A-4 Connecting to Masters from Other Manufacturers on page A-9 for the application
object references in masters and tools from other manufacturers.
