High Function Touch Screens - NT21 / NT31 / NT631
Get the Most from Your Omron PLCs
The NT21/NT31/NT631 operator interface products create superior Omron PLC solutions
by taking advantage of features that other HMI products simply cannot offer in an Omron
system. Our HMI products are designed with the same attention to quality and
performance that go into our broad line of industry leading PLCs. Omron's NT21/31/631
also offer significant programming flexibility in object layout and PLC controls, allowing
you to create the program needed to realize your operator interface vision.

High-Speed NT Link
High-speed NT Link highlights the advantages that come when you
partner an Omron PLC with an Omron touch screen. Combine
Omron’s CS1-EV1 PLCs with NT21/31/631 to benefit from 115k baud
serial communications tailored exclusively for PLC to touch screen
data. It is almost twice as fast as Host Link and 25% faster than
standard NT Link when a single NT unit is connected to a PLC serial
port. High-speed NT Link is three times faster than standard NT Link
with 8 NT units connected to a single CS1 or CJ1 serial port.

DeviceNet
The NT31 and NT631 can be quickly configured for
DeviceNet communications, integrating seamlessly
into your open DeviceNet network. This is truly a
multi-vendor PLC solution, since no modifications
need to be made to the screen data when changing
the brand of the DeviceNet master. (See the
DeviceNet Technical Discussion in the Technical
Highlights of this catalog for detailed
specifications.)
Software
NT Link
1:N
Communication
This protocol allows multiple interfaces to be
connected to one PLC communication port. It is
available with both standard and high speed NT
Link. This protocol allows you to create a multi-
drop system that puts up-to-the-second data at
locations along the production line. (See the NT
Link section in the Technical Highlights of this
catalog for more details and specifications.)
Memory Link
Directly connect the NT with a single board computer, PLC or
personal computer via RS-232C or RS-422 communications using
Memory Link. This protocol allocates a virtual memory area within
the operator interface to store data values. The screen program
references this internal memory area for all screen objects, just as
though this memory area belonged to a PLC. This means your PC
based device only has to be concerned with referencing this
memory area to read and write data values. (See the Memory Link
section in the Technical Highlights at the end of this catalog for
more details.)

Recipe Data
Recipes store rows of values within the NT memory and operators
can send that information down to the PLC to configure it for a
batch operation. The new Recipe Table editor in NTST v4.6 creates
and manages recipe information, allowing recipe data to be up- or
downloaded from the NT hardware. NTST can also work with
comma separated variable files to read in large recipe tables, or
store uploaded recipe data for future reference or use.
Background Math Function
NT31/631 units store a Mathematical Table that allows functions of
different formats to run in the background of the NT31/631 units.
The equations can be constructed of constants, values from
NT31/631 memory, or values from PLC memory locations.
Calculation results can be sent to NT31/631 internal memory or
directly to the PLC memory. Now you can convert values for
display purposes within the display device, leaving the PLC to
worry about calculations that affect your process.
Input Enable - Bit Interlock
Function
This function is suited for use as a password protection function.
The interlock function denies access to input objects (touch
switches, thumb-wheels, numeric input fields, and string input
fields) based on the status of a bit in the PLC. Each input object
within an NT31/631-EV2 project can be assigned to a unique bit or
the same bit within the PLC. If the bit is ON, the input object will
function. Turn the bit OFF and the input object is locked out.
An excellent application of this feature would be login security.
When the operator enters a password using a keypad, the PLC will
compare the entered number to the values in certain PLC memory
registers. The PLC can then change the referenced bits from 0 to 1
accordingly, granting access to different screen areas or input
objects as designated by the user’s access level.

NT21 / NT31 / NT631
Pop-Up Windows
Two window screens can be displayed in one standard screen,
maximizing screen space and application efficiency. All objects
(except thumb-wheel switches) can be displayed within these pop-
up windows allowing operators to simultaneously view different
aspects of the process as needed. Create a variety of pop-up
window screens and call them up for display in your application as
needed, either manually or from PLC memory.
Software
Alarm History, Frequency,
and Activity
Track your process and create a fault record using the alarm
history, frequency and activity functions. These pop-up windows
graphically convey problems in your process and allow you to
make corrections to save time and materials. Simply drag the
alarm object into the touch screen project, create a PLC bit
reference in an alarm bit table, add a message to that bit, and the
NT21/NT31/NT631 are ready to track and report alarms. The
complete alarm history and frequency reports can be printed from
the system menus.
Memory Unit
This portable FLASH memory module includes two 1MB banks.
Each bank can store the screen data from a fully loaded operator
interface, or the firmware program for the NT21, NT31 or NT631.
The module can be set for manual or automatically triggered
upload or download of data. In fact, the module can be configured
to first download a new firmware program and then to
automatically download new screen data. Imagine how easy it
would be to update customers in the field! No PC connection is
needed. Just plug on the module, power up the touch screen and
transfer the programs.
Programming Console
When using an Omron PLC and NT-Link communications, this
feature allows you to adjust mnemonic programming and access,
monitor, and change individual memory addresses using the
operator interface instead of a laptop or hand-held programmer.
Now, maintenance personnel no longer need to carry a hand-held
programmer or laptop from PLC to PLC to perform diagnostics. It
can be performed right from the front of the operator interface
without ever opening the control panel.

Device Monitor Function
Another feature available on the NT31/631 when using an Omron PLC,
the Device Monitor Function allows the NT to monitor tables of
individually selected PLC values, or entire ranges of a PLC memory
area. Once the values or ranges are selected, data values can be
viewed in real time as they change. There is also a window to view
errors currently active within PLC memory. Previously, only the PLC
programming software could perform these diagnostics. Now, no
laptop is needed for these basic debugging tools.
Registration Monitor
– Manually create a list of PLC addresses and
simultaneously monitor them. Update the different values by touching
the address and entering a new value with a popup keypad.
PLC Error Screen
– View the current errors in the PLC.
Continuous Monitor
- Create a table of 50 PLC addresses to monitor
and change. Simply select the initial address, and the table
automatically fills in with the next (25 for NT31, 50 for NT631)
sequential addresses.
Images and Art Objects
Bitmap images can be displayed as fixed objects or image
lamps. Image lamps have an ON state and OFF state, each
represented by a different bitmap. Image objects display
bitmap images from the image table stored within the
operator interface. This can be a fixed reference to one
image table location, or the reference can be controlled by
the PLC. This is an excellent way to quickly achieve
animation.
Touch Switches and Lamps
The original purpose of touch screens was to provide a cost effective
replacement for hardwired pushbutton and selection switches and
indicator lamps. This is still one of the primary motivations on panels
today. The NT31 and NT631 include a variety of touch switch and
lamps, as well as a library of image objects to lend that special touch.
Omron touch switches and lamps include a higher degree of control
than most touch screen products, allowing the objects to be sized,
colored, and positioned as needed. There are also many labeling
options available:
• Control bits
• Control pop-up windows
• Switch screens
• Copy values
• Input numeric & text
• Move the cursor
characters
• Execute a screen print
