Functions relating to data input
Input by touch switches
Data can be input by simply touching touch switches displayed on the screen.
The possible functions of touch switches include sending data to the host and changing the screen display.
Inputs can be enabled and disabled from the host when interlock bits have been allocated.
Pop-up window function
A window overlaying the currently displayed screen can be alternately opened and closed by pressing a touch
switch.In addition to fixed character and graphic displays, control keys and character keys created as touch
switches can also be set inside the window.
A maximum of three windows can be displayed simultaneously.
Since the window need only be opened when input is required, the screen can be used efficiently.
Numeral/character string setting function
Numeric keys and character keys can be assigned to touch switches so that numeric values and character strings
can be input at the operation site.
The input data is written to numeral/character string memory tables and also sent to the host. It is also possible to
disable input by control from the host.
Recipe function
Several words of numeric data can be edited at the PT Unit, and written to or read from the host in one operation.
Input from a bar code reader
Data read with a bar code reader can be input to a character string input field.
Functions relating to communications
Communications with the host
The NT631/NT631C can communicate with the host by four methods: host link, 1:1 NT link, 1:N NT link (standard
or high-speed), and Memory link. Data can be read from the host, and data input by means of touch switches and
numeral/character string settings can be sent to the host. It is also possible to connect with other model PCs.
Functions relating to the system
System menu
System settings and maintenance can be performed by selecting from system menus displayed on the screen.
Creation of screen data
Screen data created using the Support Tool at a personal computer can be transferred and stored in the built-in screen
data memory.
Resume function
The status and memory table contents of the NT631/NT631C immediately before its operation is stopped can be stored
while operation is stopped, or while the power is off, and then displayed on the screen again when operation is restarted.
Screen saver function
This function serves to extend the service life of the backlight and EL and prevent the formation of an afterimage on the screen.
Clock function
The time can be displayed in accordance with the internal clock data.
Programming Console function
When the NT631/NT631C is connected to a C-series CPM1, CPM2A, CPM2C, CQM1, CQM1H, or C200HX/HG/
HE(-Z)E Programmable Controller in an NT link (1:1) connection, or is connected to CS/CJ-series in an NT link (1:N)
connection, operations equivalent to those of a Programming Console (C200H-PR027-E) are possible.
Device Monitor function
When the PT is connected to a PLC in a 1:1 NT Link or 1:N NT Link, the PT can be used for operations such as
changing the PLC's operating mode, displaying or changing the PVs of words, or reading the error log.
System program install function
The system program of the NT631/NT631C can be changed by using the system installer supplied with the Support Tool
(NT-ZJ3AT1/ZJCAT-EV2). It can also be installed by using a memory unit (NT-MF261).
Screen display history function/alarm history function
The screen display history function records the time at which specific screens are displayed and the number of times
they are displayed. The alarm history function records the time at which specific bits at the host are turned ON and the
number of times they are turned ON.
Trend graph logging function and background function
Changes in the contents of numeral memory tables displayed in trend graphs can be recorded (logging function). Also, the
record can be maintained even when the trend graph is not displayed (background function).
Mathematical function
This function allows calculations to be executed continuously during PT operation when mathematical table have been set
in screen data. Arithmetic operations, bit operations, logic operations, and comparison operations can be performed.
Operations with up to 5 terms are possible.

Functions of the NT631/NT631C Section 1-2
1-2-5 Displays
The NT631/NT631C can display various kinds of elements such as characters, numeric values, graphs, lamps, and touch switches, on a screen. The
screen data displayed by the NT631/NT631C are created by using the Support Tool at a personal computer.
Characters

Fixed Displays Characters and various graphics (circles, circular arcs, sectors, polylines,
polygons and rectangles) whose display does not have to be changed, and
mark data, image data, and library data that has already been registered, can
be written directly onto the screen.
Circle SectorArc
Polyline Polygon Rectangle
* A continuous straight line
with up to 256 points can
be drawn.
* A polygon with up to
255 vertices can be
drawn.
Marks are graphics comprising 16 by 16 dots that can be used as characters.
They can be used as custom characters within character strings.
Image data are graphics comprising any required area of dots. They are registered in advance and as many as required can be displayed at any position on
the screen.
Windows bit map (BMP) data can be used for images.
There is a two-color mode, in which the display color and background color of
the image are specified when it is registered in a screen, and an eight-color
mode in which colors are assigned to the image in advance.
Since image data is composed of dots, it requires a large data size but offers
great powers of expression.
Library data are combinations of fixed display graphics registered as a single
graphic. They are registered in advance and as many as required can be displayed at any position on the screen.
Since it is generated by combining graphics, library data has a small data
size.

Functions of the NT631/NT631C Section 1-2
Mark Image data Library data
Lamps These are graphics whose display status changes in accordance with the
states of bits at the host. Squares, circles, sectors and polygons can be used
for lamps (normal (standard) lamps). In accordance with the status of the host
bit, they can be lit (displayed in reverse video) or flashed (repeated alternation
between normal and reverse video display states).
Lamps can also display different image/library data for the ON and OFF states
of the host bit (such lamps are called image/library lamps).
There are four standard lamp labels: fixed display character strings, ON/OFF
switching character strings, numeral displays, and character string displays.
When fixed display character strings or ON/OFF switching character strings
are used, several lines of labels can be displayed.
