List of NX Objects
This section describes the NX objects of the System Units.
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.
Refer to the NX-series Communication Control Unit Built-in Function User's Manual (Cat. No. Z396)
for the method to use messages to access NX objects of NX Units connected to a Communication
Control Unit.
