A-3 Special Instructions
The following table lists the instructions that you can use in the NJ-series CPU Unit for the Communica-
tions Coupler Unit and the NX Units.
Refer to the
NJ-series Instructions Reference Manual
(Cat. No. W502-E1-07 or later) for details on the
instructions.
Refer to the
NJ-series CPU Unit Software User’s Manual
(Cat. No. W501) for information on how to cre-
ate a user program that use these instructions.
This section describes the methods that you use to specify the target Unit or NX objects in special
instructions.
Use a variable assigned to the Unit to specify the target Unit in a special instruction. You must register
the variables and assign them to the Units in advance. Refer to the
NJ-series CPU Unit Software User’s
Manual
(Cat. No. W501-E1-06 or later) for details.
To specify an NX object in a special instruction, use the index and subindex for that NX object.

Change to NX Unit
Write Mode
This instruction changes the specified Communi-
cations Coupler Unit or NX Unit to the mode that
allows the writing of data.
*1
*1. You can write the parameters that are updated without restarting the Unit at any time.
NX_SaveParam
Save NX Unit
Parameters
This instruction saves data that is written to the
specified Communications Coupler Unit or NX
Unit.

*2. Always execute the NX_SaveParam instruction after you execute the NX_WriteObj instruction. If you do not
execute the NX_SaveParam instruction, the object data will return to the values before the NX_WriteObj in-
struction was executed when the Unit is restarted.
RestartNXUnit
Restart NX Unit
This instruction restarts the specified Communica-
tions Coupler Unit and all NX Units that are con-
nected to it.
