NX-series EtherCAT Coupler Unit User’s Manual (W519)
A-6 NX Objects
This section explains the NX objects that are implemented by the EtherCAT Coupler Unit.
NX objects are exclusively for EtherCAT Slave Terminals.
You can read or write these objects with special instructions that are supported by the NJ-series CPU
Unit in the Machine Automation Controller. The Read NX Unit Object (NX_ReadObj) instruction reads
NX objects, and the Write NX Unit Object (NX_WriteObj) writes NX objects. Refer to the
NJ-series
Instructions Reference Manual
(Cat. No. W502-E1-07) for details on the special instruction.
Refer to the manuals for the individual NX Units for details on the NX objects that are implemented by
each NX Unit.
This manual describes NX objects with the following format.
Items within the <> brackets are replaced with data. Each item has the following meaning.

Description
Index
This is the index of the object that is expressed as a four-digit hexadecimal number.
Subindex
This is the subindex of the object that is expressed as a two-digit hexadecimal number.
Object name
This is the name of the object. For a subindex, this is the name of the subindex.
Default
This is the value that is set by default.
Data range
For a read-only (RO) object, this is the range of the data that you can read. For a read/write
(RW) object, this is the setting range of the data.
Unit
The unit is the physical units.
Data type
This is the data type of the object.
Access
This data tells if the object is read-only or read/write.
RO: Read only
RW: Read/write
I/O allocation
This tells whether I/O allocation is allowed.
Data attribute
This is the timing when changes to writable objects are enabled.
Y: Enabled by restarting
N: Enabled at all times
---: Write-prohibited
