Unit Versions of NSJ-series NSJ Controllers

Unit Versions A “unit version” has been introduced to manage NSJ Controllers in the NSJ

Series according to differences in functionality accompanying product
upgrades.

Notation of Unit Versions
on Products

The unit version is given to above the lot number on the nameplate of the
products for which unit versions are being managed, as shown below. The
Controller Section of the NSJ Controllers has the same architecture as a CJ­series CJ1-H CPU Unit with unit version 3.0. The unit version of NSJ Control­lers thus starts from unit version 3.0.

Confirming Unit Versions
with Support Software

The CX-Programmer can be used to confirm the unit version using one of the
following methods.

• Using the PLC Information

• Using the Unit Manufacturing Information (This method can be used for
Special I/O Units and CPU Bus Units as well.)

Note CX-Programmer version 6.1 or lower cannot go online with NSJ@-@@@@(B)-

G5D Controllers. CX-Programmer version 7.0 or lower cannot go online with
NSJ@-@@@@(B)-M3D Controllers.

PLC Information

• If you know the device type and CPU type, select them in the Change
PLC Dialog Box, go online, and select PLC - Edit - Information from the

menus.

• If you don't know the device type and CPU type, but are connected
directly to the Unit on a serial line, select PLC - Auto Online to go online,
and then select PLC - Edit - Information from the menus.

In either case, the following PLC Information Dialog Box will be displayed.

3 Safety Precautions

!WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing

so may result in electric shock.

!WARNING Do not touch any of the terminals while the power is being supplied. Doing so

may result in electric shock.

!WARNING Do not use the touch switch input functions of the Display Section for applica-

tions where danger to human life or serious property damage is possible, or
for emergency switch applications.

!WARNING Provide safety measures in external circuits (i.e., not in the Programmable

Controller), including the following items, to ensure safety in the system if an
abnormality occurs due to malfunction of the NSJ Controller or another exter­nal factor affecting the NSJ Controller operation. Not doing so may result in
serious accidents.

• Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits.

xxi

Safety Precautions 3

• The NSJ Controller will turn OFF all outputs when its self-diagnosis func­tion detects any error or when a severe failure alarm (FALS) instruction is
executed. As a countermeasure for such errors, external safety measures
must be provided to ensure safety in the system.

• The NSJ Controller outputs may remain ON or OFF due to deposition or
burning of the output relays or destruction of the output transistors. As a
countermeasure for such problems, external safety measures must be
provided to ensure safety in the system.

!WARNING Confirm safety before transferring data files stored in the file memory (Mem-

ory Card or EM file memory) to the I/O area (CIO) of the Controller Section
using a Programming Device. Otherwise, the devices connected to Output
Units may malfunction regardless of the operation mode of the Controller Sec­tion.

!WARNING Fail-safe measures must be taken by the customer to ensure safety in the

event of incorrect, missing, or abnormal signals caused by broken signal lines,
momentary power interruptions, or other causes. Serious accidents may
result from abnormal operation if proper measures are not provided.

!WARNING The NSJ Controller refreshes I/O even when the program is stopped (i.e.,

even in PROGRAM mode). Confirm safety thoroughly in advance before
changing the status of any part of memory allocated to Output Units, Special
I/O Units, or CPU Bus Units. Any changes to the data allocated to any Unit
may result in unexpected operation of the loads connected to the Unit. Any of
the following operations may result in changes to memory status.

• Transferring I/O memory data to the Controller Section from a Program­ming Device.

• Changing present values in memory from a Programming Device.

• Force-setting/-resetting bits from a Programming Device.

• Transferring I/O memory files from a Memory Card or EM file memory to
the Controller Section.

• Transferring I/O memory from a host computer or from another node on a
network.

!Caution Execute online edit only after confirming that no adverse effects will be

caused by extending the cycle time. Otherwise, the input signals may not be
readable.

!Caution Confirm safety at the destination node before transferring a program to

another node or changing contents of the I/O memory area. Doing either of
these without confirming safety may result in injury.

!Caution When setting Units using the IORD or IOWR instructions, check the operation

of the ladder program and data completely before using them in actual opera­tion. Incorrect settings may cause the Unit to stop operating or may result in
unexpected operation of connected devices.

xxii

Safety Precautions 3

!Caution The NSJ Controller automatically backs up the user program and parameter

data to flash memory when these are written to the Controller Section. I/O
memory (including the DM, EM, and HR Areas), however, is not written to
flash memory. The DM, EM, and HR Areas can be held during power interrup­tions with a battery. If there is a battery error, the contents of these areas may
not be accurate after a power interruption. If the contents of the DM, EM, and
HR Areas are used to control external outputs, prevent inappropriate outputs
from being made whenever the Battery Error Flag (A40204) is ON. Areas
such as the DM, EM, and HR Areas, the contents of which can be held during
power interrupts, is backed up by a battery. If a battery error occurs, the con­tents of the areas that are set to be held may not be accurate even though a
memory error will not occur to stop operation. If necessary for the safety of the
system, take appropriate measures in the ladder program whenever the Bat­tery Error Flag (A40204) turns ON, such as resetting the data in these areas.

!Caution When installing the NSJ Controller on the door of a control panel or any other

moving object, be sure that all cables are long enough so that excessive force
is not applied to cables and connectors.

!Caution Tighten the power supply terminal block screws to the torque specified in this

manual. Loose screws may result in fire or malfunction.

!Caution Wire the polarity of the power supply correctly when using a DC power supply.

Reversing the polarity may cause abnormal operation.

!Caution Do not touch a Power Supply Unit while power is being supplied or immedi-

ately after turning OFF the power supply. The Unit may be hot and may cause
burns.

!Caution When connecting a Programming Device or other personal computer to a NSJ

Controller to which a non-insulated Power Supply Unit (e.g., CJ1W-PD022) is
mounted, either ground the 0 V side of the external power supply or do not
ground the external power supply at all ground. A short-circuit will occur in the
external power supply if incorrect grounding methods are used. Never ground
the 24 V side, as shown below.

Application Precautions 5

!Caution Failure to abide by the following precautions could lead to faulty operation of

the NSJ Controller or the system, or could damage the NSJ Controller. Always
heed these precautions.

• When opening the package, check the external appearance of the NSJ
Controller to be sure that it has not been damaged. Also, shake the NSJ
Controller gently to check for abnormal sounds.

• Do not attempt to disassemble, repair, or modify any Units.

• Do not drop the product or subject it to excessive vibration or shock.

• Install external breakers and take other safety measures against short-cir­cuiting in external wiring.

• Take appropriate measures to ensure that the specified power with the
rated voltage and frequency is supplied. Be particularly careful in places
where the power supply is unstable.

• Do not apply a force greater than 100 N on the terminal block when tight­ening the terminals.

• Do not perform withstand voltage tests on the NSJ Controller.

• The allowable thickness of the panel for mounting is between 1.6 and

4.8 mm. Secure the mounting bracket with a uniform tightening torque of
between 0.5 and 0.6 N to keep the NSJ Controller waterproof and dust­proof. The front sheet may become distorted if the tightening torque is
more than the specified limit or not uniform. Always use a panel that is
clean, undistorted, and strong enough to adequately withstand mounting
the NSJ Controller.

• Do not allow metal particles to enter the NSJ Controller while work is
being performed on the panel.

• Do not connect an AC power supply to the power terminals on the NSJ
Controller.

• Use a DC power supply with low voltage fluctuation.

• Connect power to the power terminal block using twisted-pair power lines
with a cross-sectional area of at least 2 mm

2

and always using M3.5

crimp terminals. The correct tightening torque for the terminal block is

0.8 N.

• To conform to the Low Voltage Directive in the EC Directives, use a power
supply with reinforced insulation for Expansion Racks.

• Do not pull on the cables or bend the cables beyond their natural limit.
Doing either of these may break the cables.

• Do not place objects on top of the cables or other wiring lines. Doing so
may break the cables.

• Before touching a Unit, be sure to first touch a grounded metallic object in
order to discharge any static build-up. Not doing so may result in malfunc­tion or damage.

• When transporting or storing circuit boards, cover them in antistatic mate­rial to protect LSIs, ICs, and other components from static electricity and
maintain the proper storage temperature.

• Do not touch circuit boards or the components mounted to them with your
bare hands. There are sharp leads and other parts on the boards that
may cause injury if handled improperly.

• Mount Units only after checking terminal blocks and connectors com­pletely.

xxv

Application Precautions 5

• Be sure that the terminal blocks, expansion cables, and other items with
locking devices are properly locked into place. Improper locking may
result in malfunction.

• Be sure that all the terminal screws, and cable connector screws are tight­ened to the torque specified in the relevant manuals. Incorrect tightening
torque may result in malfunction.

• Wire all connections correctly.

• Use crimp terminals for wiring. Do not connect bare stranded wires
directly to terminals. Connection of bare stranded wires may result in
burning.

• Check switch settings, the contents of the DM Area, and other prepara­tions before starting operation. Starting operation without the proper set­tings or data may result in an unexpected operation.

• Always use the power supply voltages specified in this operation manuals.
An incorrect voltage may result in malfunction or burning.

• Double-check all wiring and switch settings before turning ON the power
supply.

• When assembling and wiring connectors, check all pin numbers carefully
and wire them correctly.

• Perform all wiring according to the methods given in this and other relative
manuals.

• Always use the special cables listed in this manual or make cables
according to manual specifications. Using commercially available cables
may damage the external devices or the NSJ Controller.

• Confirm the safety of the system before turning ON or OFF the power
supply or before pressing the reset button.

• Always reset the power supply after changing switch settings.

• Leave the label attached to an I/O Unit when wiring it. Removing the label
may result in malfunction if foreign matter enters the Unit.

• Remove the label after the completion of wiring to ensure proper heat dis­sipation. Leaving the label attached may result in malfunction.

• Do not apply voltages to the Input Units in excess of the rated input volt­age. Excess voltages may result in burning.

• Do not apply voltages or connect loads to the Output Units in excess of
the maximum switching capacity. Excess voltage or loads may result in
burning.

• The user program and parameter area data is backed up in the internal
flash memory. The BKUP indicator will light on the NSJ Controller when
the backup operation is in progress. Do not turn OFF the power supply to
the NSJ Controller when the BKUP indicator is lit. The data will not be
backed up if power is turned OFF.

• Start actual system application only after sufficiently checking screen
data, macros, and the operation of the program in the Controller Section.

• When replacing the NSJ Controller, resume operation only after transfer­ring to the new Display Section and Controller Section all data required for
resuming operation. Not doing so may result in an unexpected operation.

• When using a program for which errors in the Display Section would affect
control operations, monitor for errors in the status area of the Display Sec­tion and make sure that operation functions on the safe side if an error
occurs.

xxvi

Application Precautions 5

• Do not perform the following operations while the uploading or download­ing screen data or system programs. The screen data or system program
may be corrupted.

• Turning OFF the power supply to the NSJ Controller

• Pressing the reset switch on the Display Section

• Confirm that no adverse effect will occur in the system before attempting
any of the following. Not doing so may result in unexpected operation.

• Changing the operating mode of the NSJ Controller (including the set­ting of the startup operating mode).

• Force-setting/force-resetting any bit in memory.

• Changing the present value of any word or any set value in memory.

• Use the CX-Programmer (programming software that runs on Windows) if
you need to program more than one task.

• When creating an AUTOEXEC.IOM file from a Programming Device (CX­Programmer) to automatically transfer data at startup, set the first write
address to D20000 and be sure that the size of data written does not
exceed the size of the DM Area. When the data file is read from the Mem­ory Card at startup, data will be written to the Controller Section starting
at D20000 even if another address was set when the AUTOEXEC.IOM file
was created. Also, if the DM Area is exceeded (which is possible when
the CX-Programmer is used), the remaining data will be written to the EM
Area.

• Always turn ON power to the NSJ Controller before turning ON power to
the control system. If the NSJ Controller power supply is turned ON after
the control power supply, temporary errors may result in control system
signals because the output terminals on DC Output Units and other Units
will momentarily turn ON when power is turned ON to the NSJ Controller.

• Fail-safe measures must be taken by the customer external to the NSJ
Controller to ensure safety in the event that outputs from Output Units
remain ON as a result of internal circuit failures, which can occur in relays,
transistors, and other elements.

• If the I/O Hold Bit is turned ON, the outputs from the NSJ Controller will
not be turned OFF and will maintain their previous status when the NSJ
Controller is switched from RUN or MONITOR mode to PROGRAM mode.
Make sure that the external loads will not produce dangerous conditions
when this occurs. (When operation stops for a fatal error, including those
produced with the FALS(007) instruction, all outputs from Output Unit will
be turned OFF and only the internal output status will be maintained.)

• The contents of the DM, EM, and HR Areas in the Controller Section are
backed up by a Battery. If the Battery voltage drops, this data may be lost.
Provide countermeasures in the program using the Battery Error Flag
(A40204) to re-initialize data or take other actions if the Battery voltage
drops.

• Do not perform the following operations while a Memory Card is being
accessed. In the worst case, the Memory Card may be rendered unus­able.

• Turning OFF the power supply to the NSJ Controller

• Pressing the reset switch on the Display Section

• Always following the specified procedure when removing the Memory
Card. In the worst case, the Memory Card may be rendered unusable if it
is removed while being accessed.

xxvii

Application Precautions 5

• Unexpected operation may result if inappropriate data link tables or
parameters are set. Even if appropriate data link tables and parameters
have been set, confirm that the controlled system will not be adversely
affected before starting or stopping data links.

• CPU Bus Units will be restarted when routing tables are transferred from
a Programming Device to the NSJ Controller. Restarting these Units is
required to read and enable the new routing tables. Confirm that the sys­tem will not be adversely affected before allowing the CPU Bus Units to
be reset.

• Do not connect an USB connector to any device that is not applicable.

• Before connecting an USB connector to a device, make sure that the
device is free of damage.

• Do not press the touch switch with a force greater than 30 N.

• Confirm the safety of the system before pressing touch switches.

• Do not accidentally press touch switches when the backlight is not lit or
when the display does not appear.

• Signals from the touch switches may not be input if the switches are
pressed consecutively at high speed. Confirm each input before proceed­ing to the next one.

• Before initializing screen data, confirm that existing data is backed up at
the NS-Designer.

• When changing the password with the system menu, do not reset or turn
OFF the power supply until writing is finished (i.e., until the Write Button
returns to its original condition). It may become impossible to manipulate
screens if the password is not set correctly.

• When using the device monitor, confirm the safety of the system before
performing the following operations.

• Changing monitor data

• Changing operation modes

• Forced setting or resetting

• Changing present values or set values

• To ensure safety, always set upper and lower limits when using the
numeral input function.

• Do not use benzene, paint thinner, or other volatile solvents, and do not
use chemically treated cloths.

• use chemically treated cloths.

• When connecting pin 6 (+5 V power supply line) of serial port A or B (RS­232C ports on the Display Section) to any external device, make sure that
the current capacity of the connected device is 250 mA max.

• Do not connect pin 6 (+5 V power supply line) of serial port C (RS-232C
ports on the Controller Section) to any external device except the CJ1W­CIF11 RS-422A Adapter or NT-AL001 RS-232C/RS-422A Adapter. Doing
so may damage the external device or NSJ Controller.

• When replacing parts, be sure to confirm that the rating of a new part is
correct. Not doing so may result in malfunction or burning.

• When backing up the system, use the correct Memory Card slot, as
shown in the following table.

Application Precautions 5

• A DeviceNet multidrop connector cannot be connected to serial port B on

the NSJ5-@@@@-@@@. Do not use it. DeviceNet multidrop connectors
cannot be used with the NSJ8/10/12-@@@@-@@@.

• Use only an insulated power source for DeviceNet communications.

• Always tighten the connector screws when connecting communications
connectors.

• Observe the following precautions when using the built-in DeviceNet Sec­tion.

• Enable the scan list to before operating the system.

• When adding a new node to the network, make sure that the baud rate
is the same as other nodes.

• Use specified communications cables.

• Do not extend connection distances beyond the ranges given in the spec­ifications.

• Do not short the battery terminals or charge, disassemble, heat, or incin­erate the battery. Do not subject the battery to strong shocks. Doing any
of these may result in leakage, rupture, heat generation, or ignition of the
battery. Dispose of any battery that has been dropped on the floor or oth­erwise subjected to excessive shock. Batteries that have been subjected
to shock may leak if they are used.

• UL standards required that batteries be replaced only by experienced
technicians. Do not allow unqualified persons to replace batteries.

• The backlight used in the NSJ Controller contain mercury. Dispose of the
NSJ Controller and any Batteries that are no longer required according to
all local laws and ordinances.

• When mounting a Battery, be sure that the correct model is being used.

• The life of the Battery will be shortened if the NSJ Controller is left for a
period of time without power supplied and then a Battery is mounted with­out supplying power.

• To ensure that memory is not corrupted, always turn ON the power supply
to the NSJ Controller for at least 5 minutes before replacing the Battery
and then complete replacing the Battery within 5 minutes after turning
OFF the power supply.

• The following precautions apply to Power Supply Units with Replacement
Notification.

• When the LED display on the front of the Power Supply Unit starts to
alternately display “0.0” and “A02” or the alarm output automatically
turns OFF, replace the Power Supply Unit within 6 months.

• Separate the alarm output cables from power lines and high-voltage
lines.

• Do not apply a voltage or connect a load to the alarm output that ex­ceeds the rated voltage or load.

• Maintain an ambient storage temperature of

−20 to 30°C and humidity

of 25% to 70% when storing the product for longer than 3 months to
keep the replacement notification function in optimum working condi­tion.

xxix

Conformance to EC Directives 6

• Always use the standard installation method. A nonstandard installa­tion will decrease heat dissipation, delay the replacement notification
signal, and may degrade or damage the internal elements.

• Design the system so that the power supply capacity of the Power Supply
Unit is not exceeded.

• Do not touch the terminals on the Power Supply Unit immediately after
turning OFF the power supply. Electric shock may occur due to the resid­ual voltage.

6 Conformance to EC Directives

6-1 Applicable Directives

•EMC Directives

6-2 Concepts

EMC Directives

OMRON devices conform to the related EMC standards so that they can be
more easily built into other devices or the overall machine. The actual prod­ucts have been checked for conformity to EMC standards (see the following
note). Whether the products conform to the standards in the system used by
the customer, however, must be checked by the customer.

EMC-related performance of the OMRON devices that comply with EC Direc­tives will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel on which the OMRON devices are installed.
The customer must, therefore, perform the final check to confirm that devices
and the overall machine conform to EMC standards.

Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:

EN 61131-2

xxx

Conformance to EC Directives 6

6-3 Conformance to EC Directives

The NSJ Controllers comply with EC Directives. To ensure that the machine
or device in which the NSJ Controller is used complies with EC Directives, the
NSJ Controller must be installed as follows:

1,2,3... 1. The NSJ Controller must be installed within a control panel.

2. You must use reinforced insulation or double insulation for the DC power
supplies used for the NSJ Controller, Expansion Racks, and I/O power
supplies. The DC power supply for the NSJ Controller and Expansion
Racks must have an output hold time of 10 ms min.

3. NSJ Controllers also conform to EMI Standard (EN61131-2). Radiated
emission characteristics (10-m regulations) may vary depending on the
configuration of the control panel used, other devices connected to the
control panel, wiring, and other conditions. You must therefore confirm that
the overall machine or equipment complies with EC Directives.

4. This is a class A product. In residential areas it may cause radio interfer­ence, in which case the user may be required to take adequate measures
to reduce interference.

6-4 Relay Output Noise Reduction Methods

The NSJ Controllers conforms to the Common Emission Standards
(EN61000-6-4) of the EMC Directives. However, noise generated by relay out­put switching may not satisfy these Standards. In such a case, a noise filter
must be connected to the load side or other appropriate countermeasures
must be provided external to the NSJ Controller.

Countermeasures taken to satisfy the standards vary depending on the
devices on the load side, wiring, configuration of machines, etc. Following are
examples of countermeasures for reducing the generated noise.

Countermeasures

(Refer to EN61000-6-4 for more details.)
Countermeasures are not required if the frequency of load switching for the

whole system with the NSJ Controller included is less than 5 times per
minute.

Countermeasures are required if the frequency of load switching for the whole
system with the NSJ Controller included is more than 5 times per minute.

Yes Yes If the load is a relay or solenoid, there is

a time lag between the moment the cir­cuit is opened and the moment the load
is reset.

If the supply voltage is 24 or 48 V, insert
the surge protector in parallel with the
load. If the supply voltage is 100 to
200 V, insert the surge protector
between the contacts.

The capacitance of the capacitor must
be 1 to 0.5 µF per contact current of
1 A and resistance of the resistor must
be 0.5 to 1 Ω per contact voltage of 1 V.
These values, however, vary with the
load and the characteristics of the
relay. Decide these values from experi­ments, and take into consideration that
the capacitance suppresses spark dis­charge when the contacts are sepa­rated and the resistance limits the
current that flows into the load when
the circuit is closed again.

The dielectric strength of the capacitor
must be 200 to 300 V. If the circuit is an
AC circuit, use a capacitor with no
polarity.

No Yes The diode connected in parallel with

the load changes energy accumulated
by the coil into a current, which then
flows into the coil so that the current will
be converted into Joule heat by the
resistance of the inductive load.

This time lag, between the moment the
circuit is opened and the moment the
load is reset, caused by this method is
longer than that caused by the CR
method.

The reversed dielectric strength value
of the diode must be at least 10 times
as large as the circuit voltage value.
The forward current of the diode must
be the same as or larger than the load
current.

The reversed dielectric strength value
of the diode may be two to three times
larger than the supply voltage if the
surge protector is applied to electronic
circuits with low circuit voltages.

Yes Yes The varistor method prevents the impo-

sition of high voltage between the con­tacts by using the constant voltage
characteristic of the varistor. There is
time lag between the moment the cir­cuit is opened and the moment the load
is reset.

If the supply voltage is 24 or 48 V, insert
the varistor in parallel with the load. If
the supply voltage is 100 to 200 V,
insert the varistor between the con­tacts.
