Safety Instructions
Please read this manual and the related documentation thoroughly
and familiarize yourself with product information, safety instructions
and other directions before installing, operating, performing
inspection and preventive maintenance. Make sure to follow the
directions correctly to ensure normal operation of the product and
your safety.
Installation Environment
WARNING • If this product is used in a situation that may cause
personal injury and/or significant product damage,
implement safe measures such as use of fault-safe
equipment.
• Do not use this product under the conditions exposed
to explosive gases. It may cause an explosion.
ATTENTION • Make sure to use an external device when configuring
the protective circuit breakers for emergencies or
interlock circuits.
• Fasten the terminal screws tightly to ensure that the
cable connection is secure. Incorrect cable connection
may cause overheating and product malfunction.
• Operate and keep the product under the allowed
conditions directed in product specifications.
Otherwise it may cause overheating and product
malfunction.
• Do not disassemble or remodel the product.
Otherwise it may cause an electric shock or
malfunction.
• Do not touch the terminals when the power is on.
Otherwise it may cause an electric shock.
ATTENTION Do not install your PLC system if any of the following
conditions are present:
• Ambient temperature outside the range of 0 to 55 °C
(32 to 131 °F)
• Direct sunlight
• Humidity outside the range of 30% to 85%
(non-condensing)
• Chemicals that may affect electronic parts
• Excessive or conductive dust, or salinity
• High voltage, strong magnetic fields, or strong
electromagnetic influences
• Direct impact and excessive vibration

6
ATTENTION Electrostatic Discharges
Under dry condition, excessive electrostatic discharges
may occur. Make sure to remove electrostatic
discharges by touching a grounded metal piece before
touching your controller system modules.
ATTENTION Cleaning
Never use chemicals such as thinner because they melt,
deform or discolor PCB boards.
ATTENTION Precautions for use of power
• Run your PLC system only after the I/O devices and
motor devices have started. (For example, first power
on in the PROG mode, then change the operation
mode to RUN.)
• Make sure to power off I/O devices after ensuring PLC
operation is stopped.
• If you power on/off I/O devices when the PLC system
is in operation, the system may malfunction because
input signal noises may be recognized as normal
inputs.
ATTENTION Before powering on
Make sure to follow these directions before powering
on your PLC system.
• When installing the system, ensure that there are no
metal chips or conductive fragments that stick to
wiring cables.
• Ensure that power supply and I/O wirings and power
supply voltage are all correct.
• Securely fasten installation and terminal screws.
• Set the operation mode switch to PROG mode.

• High-capacity programming and memory backup
The NX-CPU700p allows you to program up to 20K words.
Built-in flash EEPROM allows you to save programs separately.
•Self-diagnostics
Self-diagnostics allows you to minimize system errors and
maximize diagnostic efficiency.
• Maximum 1600 I/O points
With a 12-slot base backplane and a 12-slot expansion
backplane, you can use up to 1600 I/O points (when all I/Os are
configured with 64-point digital I/O modules).
• Supports various I/O and specialty modules
The NX-CPU700p processor module supports 24V dc input (16,
32, and 64 points), 110V ac input, 220V ac input, relay output,
transistor output (16, 32, and 64 points), SSR output, A/D, D/A,
RTD, TC, high-speed counter, CCU+, and SCU.
• WinGPC as programming tool
WinGPC, which is the programming tool for NX-CPU700p
processor module, lets you create, edit, download, and upload
your control program, and allows you to peform processor
status monitoring, force I/O, and I/O status montioring as well. It
is a powerful, easy-to-use programming tool.
• Various I/O backplane options (up to 12 slots)
The NX-CPU700p PLC allows you to choose one from
3-, 5-, 8-, 10-, or 12-slot backplanes for maximum system
configuration flexibility.
• Built-in RS232C/RS485, 2 ports
With two built-in communication ports, the NX-CPU700p
processor module allows you to connect directly to computers
or touch panels and exchange a high volume of data at high
speed. The COM2 port supports a simple user-defined
communication, and allows you to connect to barcode readers,
inverters, or servo motors. (Binary communication is available.)

Backplane and Expansion Cable
Backplane (NX-BASE03, NX-BASE05, NX-BASE08,
NX-BASE10, NX-BASE12)
Description
1. Backplane mounting hole
This hole is for mounting a backplane on a control panel (control box).
Use M5 screw for mounting.
2. Module mounting guide holes
When mounting a module on the backplane, align the mounting clamp of
the module with this hole.
When using as a base backplane (processor side backplane), mount
modules, starting from the leftmost slot, in the order of power supply
module, processor module, and I/O (specialty) modules.
When using as an expansion backplane, mount modules, starting from
the leftmost slot, in the order of power supply module and I/O (specialty)
modules.
3. Connector for processor module
Mount the processor module onto this slot. Make sure to mount the
processor module next to the power supply module. When using as an
expansion backplane, I/O (specialty) modules can also be mounted onto
this slot.
4. Connectors for I/O modules (specialty modules)
Mount I/O (specialty) modules onto these slots.
5. Module fixing hole
These holes are for holding a mounted module in place on a backplane.
Fasten the screw on the module through this hole.
6. Connector for power supply module
7. Connector for expansion cable
When using as an exansion backplane, use this connector to connect an
expansion cable.

• Status LEDs
• Mode switch
• Initialize switch
When set to the INIT position, all CPU errors are cleared. This operation is
valid only when the Mode switch is set to PROG mode.
LED Color Description
RUN Green On when the processor is running.
PROG Green On when the program can be edited.
BATT Red On when the battery is not mounted or is low.
TEST Green Not used
COM1 Green Flashing when the processor is communicating via COM1.
COM2 Green Flashing when the processor is communicating via COM2.
ERROR Red On when a processor error occurs.
Mode Description
RUN Sets the processor operation mode to RUN mode.
RMT Sets the processor operation mode to RUN or PROG mode.
PROG Stops the processor, i.e, sets the processor operation mode to PROG mode.
