Installation Instructions
NTXS series units should be mounted on a panel. Gasket and mounting clamps are provided with each
NTXS unit for proper mounting.
Environmental Considerations:
Make sure that the unit is installed correctly and that the environmental operating limits are followed (see
Specifications for NTXS).
Do not operate NTXS in areas subject to explosion hazards due to flammable gases, vapors or dusts.
NTXS should not be installed where fast temperature variations are present.
Location Considerations
Care should be taken when locating equipment behind the NTXS. Ensure that AC power wiring, PLC output
modules, contactors, starters, relays and any other source of electrical interference are located away from
NTXS.
Particular care should be taken to position Variable speed drives and switching power supplies away from
the NTXS .
Panel Mounting
Follow the procedure given below for proper mounting:
1) Make a cutout of the required size. Panel cutout tolerance is + 0.1mm.
2) Put the gasket behind the bezel (see dimensional sketch for details).
3) Put the NTXS unit through the panel cutout.
4) Insert the clamps into the case.
5) Pullback the clamps until they seat into the retaining slots.
6) Tighten the clamping screws in an even pattern until the NTXS unit is secured into the
panel.
This section presents the dimensional sketches and panel cutouts for NTXS models.

Power and communication wiring must be in accordance with Class I, Division 2 wiring methods (Article 5014 (b) of the National Electrical Code, NEPA 70) and in accordance with the authority having jurisdiction.
A.
“THIS EQUIPMENT IS SUITABLE FOR USE IN CLASS I, DIVISION 2,
GROUPS A, B, C AND D OR NONHAZARDOUS LOCATIONS ONLY.”
B.
“WARNING - EXPLOSION HAZARD - SUBSTITUTION OF COMPONENTS
MAY IMPAIR SUITABILITY FOR CLASS I, DIVISION 2.”
C.
“WARNING - EXPLOSION HAZARD - DO NOT DISCONNECT
EQUIPMENT UNLESS POWER HAS BEEN SWITCHED OFF OR AREA IS
KNOWN TO BE NONHAZARDOUS.”
!
!
!
Please follow the instructions given below while making power supply connections for models:
Follow the wiring diagram on the sticker of the unit which shows terminals.
To make a connection strip about 7mm of insulation of the wire, turn the connector screw
counter-clock wise until the gap is wide open. Insert the wire all the way in and turn the screw
clockwise until it is tight.
Wire lengths should be minimum. Wires should run in pairs with a neutral or common paired with a
live or signal wire.
NTXS +24VDC model is fused internally with a self resetting 60V, 400mA fuse. It is recommended
that all input power lines be protected from product failure by a fuse or breaker.
Adequate strain relief must be provided for the power connector, to ensure that vibration does not
cause the power connector to be pulled out.
All the NTXS products are housed in a moulded ABS plastic case which eliminates any
electrical shock hazard. Hence Safety Earth is not required to be connected to the chassis of the
unit.
The DC ground is not directly coupled to Earth ground internally. The unit is designed to operate
properly whether or not the DC ground is connected to the Earth ground. We do recommend,
however, that if the DC ground has to be connected to the Earth ground, the Earth connection
Page 20
Hardware
should be made to a central star point as poor site earths can introduce noise into a system.
Do not power unit and inductive loads with the same power supply even though there is enough
immunity in the NTXS to withstand the transients present on these lines. Avoid using power
supplies with large capacitive outputs which may cause problems if power is cycled within a short
time period.
If wiring is to be exposed to lightening or surges, use appropriate surge suppression devices.
Keep AC, high energy and rapidly switching DC wiring separate from signal wires.
Connecting high voltages or AC power mains to the DC input will make unit unusable and may
create an electrical shock hazard to personnel. Such a failure or shock could result in serious
personal injury, loss of life and/or equipment damage. DC voltage sources should provide proper
isolation from main AC power and similar hazards.

Communication Ports
NTXS models have two communication Ports.
One port of NT2S models has RS232/CMOS signals. This port is used to connect to PLC. The other port
has RS232 signals and this port is used for receiving configuration setup and printing.
NT3S has Multi-Signal ports meaning RS232/RS485/CMOS signal level ports. NT3S units can
simultaneously communicate with two devices on these serial ports. Units can receive data from PC on
either of the ports. Both the ports are also capable of Serial Printing. Each port has to be configured for
their function. Even if both the ports are connected to PLC, user can download data from NT-XS software
on either of the ports. For Programming cable details, please refer to Appendix.
Different cables are required for different devices. Cable details for any particular device are given in the
Operation Manual of that device. Pin description of the communication Ports for NT2S and NT3S models is
as given in following pages.

Application - Tags, Screens, Keys and Tasks
PLC Communications
Page 25
Getting Started
3.1
Introduction
Each NTXS communicates with one or two devices over its serial ports to get the information required by the
operator. ‘PLC’ term is used for any device mainly PLC / controller / Inverter. Information could be the value of
a PLC register or the status of a PLC coil / bit. This information is displayed on the LCD display of the unit. If
required, NTXS can also change the values of PLC registers / coils. Supported PLC’s list is shown in the
Network Configuration window of the Setup Software.
3.2
Application - Tags, Screens, Tasks and Touch Screen / Keypad
Microsoft Windows® based configuration software, NT-XS , configures the NTXS units. ‘Configuration’
means making the NTXS unit work as per the system requirements. For example, NTXS can be configured
to be used with PLC, display register data read from the PLC, perform key action to edit PLC data. The
complete configuration for a unit is termed as ‘Application’. Application comprises of Tag Data base,
Screens, Key Definitions, Alarms and Tasks.
Each register in the PLC memory has a unique address and can be identified by giving a specific name to
it. This information is stored as Tag Data Base in NT-XS Setup Software. Any coil or register to be used in
the application is known as a Tag and must be first defined in the Tag data base.
The LCD display on the NTXS unit displays the PLC data on a ‘Screen’. PLC data can be arranged on a
screen using different objects.
Operator can control the process by actually changing the value of PLC registers. This is possible with the
help of the Touch Screen keys. Different tasks can be assigned to keys on the NTXS keypad.
Any register can be constantly monitored if alarms are defined for it. When alarm condition is reached, the
respective alarm is displayed on the screen.
Once the application is defined, firmware for the specific unit and PLC is downloaded and then application
is downloaded into the unit. NTXS can now communicate with a PLC. To download application / firmware,
connect appropriate programming cable to Serial port of NT2S models. Setup can be downloaded on any one
of the ports of NT3S models.
3.3
PLC Communication
NTXS can communicate with a PLC without any change in the NTXS hardware. To communicate with a
PLC, NTXS unit needs:
1. Proper Communication Driver for the PLC
2. NTXS - PLC communication cable
1. Communication Driver for the PLC:
Each PLC has a defined protocol for communicating with any device. Communication Driver is downloaded in
to NTXS unit along with the firmware. Communication driver varies from PLC to PLC. This driver enables
the unit to talk to a specific PLC, such as Omron PLCs.
2. NTXS - PLC Communication Cable: Proper NTXS - PLC cable is required for error free communication
with PLC. Please refer to the table given on next page for details on cables for different models.

4.2
Screens
Operator can view required information on the display of NTXS unit. This information can be arranged in such
a way that the operator can very easily interpret the information received. This can be done by using various
tools. These tools are the objects. Each screen can have various types of objects with different properties.
Up to 65534 screens can be defined depending on the application memory available. Touch screen products
have two different types of screens - Base screen and Popup screen. Base screen is the normal screen,
Popup screen can be displayed only when required on the base screen.
Page 33
Understanding NTXS Features
User should know some Screen basics while working with screens.
1. Number:
Each screen must have a unique Screen Number. Please refer to following table for details on Screen
number:
Touch panels
Keypad Panels
Base Screen
1 - 65000
1 - 65534
Popup Screen
65001 - 65534
NA
2. Name
User may want to give different names to screens. Screen name can be upto 20 characters long. These
screen names will not be displayed on the product’s actual screen. These names will only be displayed in
the configuration software. The screen name will be displayed in the screens window. This information is
stored in the application but not downloaded to the unit.
3. Description
Description of screen can be added for more info on the screen. Description is displayed only in Screen
Information window of each screen. This information is stored in the application but not downloaded to the
unit.
4. Password
Access levels can be achieved by introducing a password for a screen. Password value can vary between 1 9999. When Password is set to 0, screen is not protected. Unless user enters the correct password, the
screen will not be displayed. Any screen can be password protected. For touch panels, a popup window will
appear for the user to enter the password.
5. Associated Screens
Associated screen can be especially useful in cases where one or more objects are common between
different screens. The common part from all the screens is placed in a screen and this screen is associated
with the other screens. Any screen can be associated to another screen.
Advantages of associated screens:
1. Saves application memory.
2. Saves time of the application programmer.
Please note:
- Only one screen can be associated to any screen.
- No data entry object can be placed in the screen to be associated.
- User can embed a NTXS tag in associated screen. Embedding a PLC tag is not supported
in the associated screen. User can read the PLC tag in associated screen by coping the
required tag to internal tag. To embed a PLC tag, In Global Task-List the required PLC tag
should be copied to an internal tag. The internal tag can be embedded in the screen to be
associated.
6. Screen Type
For touch panels, data entry objects require a numeric keypad to modify the data. This keypad occupies
space when not in use. In such case user can use a data entry object with popup keypad. When user clicks
on the data entry object, a new screen is displayed on the original screen. This screen has the required
keypad, user can modify the data and close the popup screen. User can modify the data without the numeric
keypad occupying space on the screen. Screens with numbers from 1 to 65000 are the base screens.
Screens with numbers from 65001 to 65534 are popup screens.
7. Screen Task-List
Tasks can be triggered at three instances for a screen.
Page 34
Understanding NTXS Features
- Before showing: These tasks are performed before displaying a particular screen on the display.
- While showing: Tasks are repeatedly performed while the screen is displayed.
- After Hiding: Tasks are performed after another screen is called and before displaying a new
screen.
8. Screen Properties
Screens can be printed on a serial printer. Depending on it’s printing properties, screens can be of three
types:
- Print-only
The screen will be printed as soon as it is triggered. The screen will not be displayed
Maximum number of characters printed will be set from NTXS Settings menu.
- Display
The screen will only be displayed.
- Print once and Display
The screen can be printed as well as displayed. When screen is called, the screen is first
displayed and then printed once.
To print any data on NT3S models, user has to select protocol of one of the ports as Native Serial Driver from
Network Configuration. Communication settings of this port such as Baud, Parity, Bits, Number of columns,
Terminating characters, Maximum characters per screen for the Printer port can be set from the Port Settings. If one port is defined as Native serial driver, this port can not be used as a PLC port. If none of the
ports are defined as Printer ports, serial printing will not be done. For NT2S models, data is printed on the
serial port. Communication settings for serial printing can be set from NTXS settings window.
9. Show / Hide Animation
Objects on the screen can be hidden / flashed depending on the value / status of a tag. Please refer to
Screen objects for details.
4.2.1 Screen Objects:
NT-XS software allows the user to arrange the data on the screen in a way that’s suitable for the user.

2. Use keys with definition ‘Increase Digit by 1’ or Numeric keys ‘0’ and ‘1’ to edit coil data.
3. Press key with definition ‘Accept Data Entry’ (generally key legend is ENT) to accept the
data entered.
3. Register Data Entry:
Registers, internal or external, with Read/Write permission can be modified using this object. For
NT3S models, data Entry can not be performed unless a Numeric Keypad or a Popup keypad is
present on the screen. Numeric Keypad object assigns tasks for the Touch Keys in the specified
area. Procedure to edit a register is as follows:
1. Press key with definition ‘Accept Data Entry‘ to initiate data entry mode. Data entry mode
is indicated by flashing the last digit of the register. Key with definition ‘Clear Data Entry’
clears the data in the object. Key with definition ‘Cancel Data Entry’ cancels the data
entered and exits data entry mode.
2. Use ‘Numeric keys ‘0’ through ‘9’ to edit register data. For models without numeric keypad,
use keys ‘Increase Digit by 1’ and ‘Shift Value to Left’. To edit signed data, use
‘Sign (+/-)’ keys to modify the sign.
3. Press ‘Accept Data Entry‘ key to accept the data entered.
When a new application is created each key is assigned a default definition by the software. Please
note that the unit must have above mentioned key definitions to edit any register tag. In NTXS
default keys for register data entry are “ENT”, “ESC” and the numeric keys from “0” through “9”.

4.3
Real Time Trend:
This wizard plots the instantaneous tag values on Y axis against real time on x axis. This object is
supported in NT3S models only. The method of plotting used is “Paper move” plotting where every
new point is plotted at extreme right on X axis and previous values are shifted to the left. You can
pass any two byte tag [PLC tag or NTXS tag] for trending.User can plot only one tag in a single
trend window and there can be only one such window on any screen. Here we can pass the X
and Y axis limits at design time as in case of conventional wizards or via tags at runtime. The limits
for time entered as span on X axis is between 1 second to 86400 second [86400 seconds = 24 Hr].
If the limits for x or y axis are passed in indirect manner and if they are wrong then appropriate error
message is displayed in the error message window of the trend object. This object is only available
in NT3S models.
Keys / Touch screen keys
NT2S models have keypads whereas NT3S models have touchpanels for user input. User can define keys as
per the application requirement. NT-XS software enables user to define key tasks. Most of the tasks mentioned in the task list are supported as keys tasks.
4.3.1 Keypad
Keys can have two types of definitions: Local and Global.
Any key can have different tasks for different screens. This is Local definition of the key. Each key on the
keypad can have Local definition. Local Key has precedence over Global Key definition. Global definition for
any key is same for the application. When a key needs same definition for all the screens, this key can be
defined as a global key with no local definition. This saves time of application programmer.
4.3.1 Touchscreen Keys
Touchpanels have touchscreens for user input. User can place bit buttons, word buttons and numeric keypad
objects on screen. These objects are nothing but keys with various definitions. There are no Global and local
keys for touch screen keys. All the key objects defined are screen specific. Only in case of popup and
associated screen the key on active screen can overlap that on the base screen. Key on the active screen
will be sensed. Key tasks are same as Keypad tasks.
4.4
Alarms
NTXS supports maximum 256 discrete alarms. 16 bits of 16 different tags can trigger alarms. Alarm text
should be defined from Define alarms window. Tags need not be consecutive. Any internal or PLC tag can be
defined as an alarm tag. Each bit that has been defined as alarm bit is continuously monitored and when
that bit turns on ‘1’ an alarm is triggered. This alarm is placed in an container. This alarm is cleared from the
container only when the alarm bit is cleared and the alarm is acknowledged.
These alarms can also be stored as Historical alarms. User has to enable the History option in alarm
definition window. Defining alarms is not enough, these alarms must be displayed on the screen. An alarm
object must be placed on the screen for alams to be displayed. If alarms are critical each screen must have
an alarm object along with acknowledge and next / prev alarm keys. If alarms on PLC tags are to be displayed, user can do the following:
- copy the required tag to internal tag in global application task list.
- define alarms on the internal tag.
- create a screen which has only an alarm object at the bottom of the screen. This screen can be
associated with all the other screens. User, should however take care of the possible overlap of
objects.
- For models with keypad, user can define global keys to acknowledge, go to next / prev alarm.
Page 38
Understanding NTXS Features
To display alarms user must follow steps given below:
1.
Define consecutive or discrete alarms from ‘Define Alarm’ window. Definition contains the
alarm text and print selection.
2.
In Screen Definition, place Alarm object on the appropriate location.
Alarms will be displayed only if the current screen has an alarm object. If the current screen does not have
an alarm object, alarms will not be displayed.
4.5
Application Task-List
Application task-list allows user to define tasks to be performed after unit is powered on or while
application is running. Application task-lists are of two types:
1.
Power-on tasks:
Power-on tasks are performed after NTXS unit is powered on. These tasks are like a boot sequence
for NTXS which are performed only once after power up. Using these tasks user can initialize some registers, Goto a particular screen after power up etc. Please note that user MUST specify the screen to be
displayed after poweron. This can be done either by “Goto screen’ task or ‘Copy tag to STR’ task.
2.
Global tasks:
Global tasks are performed regularly till the application is running on the unit. These tasks are useful when
the user wants to perform some tasks repeatedly.

Introduction to Configuration Software - NT-XS
NT-XS is Microsoft Windows® based software to configure the NTXS* series models by Omron. NT-XS’s
tools and easy approach can help you create your applications quickly and easily. By using some of NT-XS’s
new features, you can be more effective in what you need. Whether you need a small application to monitor
data or a bigger application for both monitoring and changing data in your PLC. The common functionality
found among many Windows applications can also be found here and will allow you to quickly adapt to
NT-XS .
You can use NT-XS to configure NTXS model to work with ANY of the supported drivers. NT-XS currently
supports over 20 PLCs.
User must first configure NTXS unit for operating with a specific PLC. The NTXS communicates with a PLC
only after downloading the correct driver and application into the unit. The NTXS user should follow the
procedure to configure and use the NTXS :
1.
Create an application for required PLC.
2.
Apply power to NTXS.
3.
Connect the programming cable to the communication port of NT2S marked as ‘Serial Port’. For
NT3S any port can be used for downloading/uploading.
4.
Download Firmware i.e. driver for the PLC. NTXS unit requires a PLC driver to communicate with the
PLC.
5.
Download application.
6.
Now connect to the PLC with the correct PLC cable.
*NT2S-SF123B-EV2 and NT2S-SF127B-E models do not require any setup. PLC should be
programmed to work with these models

Frequently Asked Questions
7.1
How Do I ?
This chapter answers the questions users often ask.
1.
How do I read PLC data?
To read any PLC data, the required tag should be defined in the Tag Database. In a screen the tag should
be embedded in the required format.
2.
Can I edit PLC data? How?
Any PLC register / coil can be edited except for ‘Read only’ registers / coils. Generally System registers
and Input coils are ‘Read only’. ‘Read only’ registers / coils vary from PLC to PLC. Please refer to PLC
manual for details. To edit any PLC data define the tag in Tag Database. Place a ‘Data Entry’ object in a
screen. Make sure to define the required keys.
3.
Can I keep a record of the Process data?
NTXS model can send screen data (Alphanumeric data only) on its serial port. This output can be given to a
serial printer and a record of events can be achieved. A screen with ‘Print Data’ task can print all the alphanumeric objects.
4.
Can I change screens using PLC logic?
Any PLC tag can be copied to STR, a system register internal to NTXS , and NTXS will display the corresponding screen. User must define the task ‘Copy tag to STR’ in Global Application Task-List. Make sure to
define screens to all the possible values of the tag to avoid ‘Screen not defined’ message. Please note that
the ‘Goto screen’, ‘Goto next screen’ and ‘Goto previous screen’ tasks will not work in this case. To change
the screen the value of the PLC data should be changed.
5.
Can I perform any task continuously?
To perform any task, continuously define the task in Global Application Task-List. This task will be performed till the unit is powered down.
6.
How can I ‘Hold’ any Bit on or off using a key?
To hold a bit on using a key, define ‘Turn bit on’ task in ‘Key press task-list’ and ‘Turn bit off’ task in ‘Release key task-list’ for the same key.
7.
How do I keep any screen or any key locked?
Any screen can be kept secret using the ‘Password’ feature for NTXS models. Password protected screen
will not be displayed till the user enters the correct password. In case of NT2S Keys can be protected using
the key password.Task for password protected key will not be performed till user enters the correct
password.
8.
Can I assign scaling factor for any tag?
Value of any tag can be converted into the required format by performing ‘Math Operations’ on it. This does
not change the value of the actual tag. ‘Math Operations’ can be performed in ‘Display NT-XS / PLC Data’
objects. Data to be written to a tag can also be manipulated by assigning ‘Math Operations’ in ‘Data Entry’
object.
9.
Can I limit the data to be entered in a tag?
Data entered in any register tag can have high and low limits. This keeps a check on the register limits.
Refer to ‘Configuration software’ section for detailed information on how to define an application
