Part Names and Functions
CPU Unit
The following two models have the different numbers of the option board slots and built-in I/O points, but the names and functions of their parts
are the same. Refer to the Ordering Information page for the CPU Unit models and specifications such as the number of built-in I/O points.
*1. To use Safe Mode, set the DIP switch as shown below and then turn ON the power supply to the Controller.
If the power supply to the Controller is turned ON with the CPU Unit in Safe Mode, the CPU Unit will start in PROGRAM mode. Use the Safe
Mode if you do not want to execute the user program when the power supply is turned ON or if it is difficult to connect the Sysmac Studio.
For information on Safe Mode, refer to the NJ/NX-series Troubleshooting Manual (Cat. No. W503).
*2. Refer to the NJ/NX-series CPU Unit Software User’s Manual (Cat. No. W501) for details on backing up data.
Letter Name Function
A SD Memory Card connector Connects the SD Memory Card to the CPU Unit.
B DIP switch Used in Safe Mode *1 or when backing up data *2. Normally, turn OFF all of the pins.
C SD Memory Card power supply switch Turns OFF the power supply so that you can remove the SD Memory Card.
D DIN Track mounting hook These hooks are used to mount the Unit to a DIN Track.
E Input terminal block
This terminal block is used for wiring for the Unit power supply, grounding, and built-in
input.
F Input indicator Shows the operation status of the built-in input.
G Unit hookup guides These guides are used to mount an NX Unit or End Cover.
H NX bus connector This connector is used to connect the CPU Unit to the NX Unit on the right of the CPU Unit.
I
Option board slot 1 (left),
Option board slot 2 (right)
Remove the covers of the slots and mount Option Boards. For the models with 24 built-in
I/O points, only one slot is provided. Keep the removed covers in a safe place.
J Output indicator Shows the operation status of the built-in output.
K Output terminal block This terminal block is used to wire the built-in output.
L CPU Unit operation status indicator Shows the operation status of the CPU Unit.
M Battery connector Connector to mount the backup battery that is sold separately.
N Battery slot Used to mount the backup battery that is sold separately.
O Built-in EtherCAT port (port 2) Connects the built-in EtherCAT with an Ethernet cable.
P Built-in EtherNet/IP port (port 1) Connects the built-in EtherNet/IP with an Ethernet cable.
Q SD Memory Card cover Cover for the SD Memory Card and DIP switch. The cover swings upward.
R End Cover
Cover to protect the CPU Unit and NX Units.
One End Cover is provided with the CPU Unit.
S Battery cover Cover for the battery slot. Remove this cover when you mount/remove the battery.
T ID information indication Shows the ID information of the CPU Unit.
U DIN Track contact plate This plate is connected internally to the functional ground terminal on the terminal block.

Option Board
Specifications of Serial Communications Option Board
*1. Projecting parts such as a terminal block is not included. When the Option Board is mounted to the CPU Unit, it protrudes through the CPU
Unit surface. Refer to the NX-series NX1P2 CPU Unit Hardware User’s Manual (Cat. No. W578) for details.
*2. The terminals are isolated from the internal circuits of the CPU Unit.
