NX-series IO-Link Master Unit User’s Manual (W567)
A-3 List of NX Objects
This section explains the NX objects of the IO-Link Master Unit.
The method to access NX objects through instructions or other messages depends on where the NX
Unit is connected.
If the NX Unit is connected to a CPU Unit, access is possible with the Read NX Unit Object instruction
and the Write NX Unit Object instruction.
When the NX Unit is connected to a Communications Coupler Unit, the method depends on the con-
nected communications master and Communications Coupler Unit.
Refer to the user's manual for the connected Communications Coupler Unit for method to use mes-
sages to access NX objects on Slave Terminals.
In this manual, NX objects are described with the following format.

Index (Hex)
: This is the index of the NX object that is expressed as a four-digit hexadecimal
number.
Subindex (Hex)
: This is the subindex of the NX object that is expressed as a two-digit hexadeci-
mal number.
Object name
: This is the name of the object. For a subindex, this is the name of the subindex.
Default value
: This is the value that is set by default.
Data range
: For a read-only (RO) NX object, this is the range of the data you can read. For a
read-write (RW) NX 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 NX objects are enabled.
Y: Enabled by restarting
N: Enabled at all times
---: Write-prohibited
