Port A for Common Use by Support Tool/Host and Port B for Exclusive Use by the Host

•Communications with the host is possible via another port while connected to the Support Tool.

•Reading bar code data from a bar code reader is possible via another port while communicating with the host.

•Installing a Memory Unit (type NT-MF261) on the rear of the NT631/ NT631C makes it easy to write screen data into the NT631/NT631C on site. This enables a rapid response to setup changes.

•NT631/NT631C can store a system program into a Memory Unit. This enables the system to handle more flexible setups.

Screen data can be checked simply by operations at the NT631/NT631C system menu, without connecting up to the Support Tool.

The number of elements that can be registered on one screen has been considerably increased, making it possible to create more expressive screens. For details, refer to Display Restrictions in Appendix A Specifications of the NT31/NT31C/NT631/NT631C Programmable Terminal Reference Manual.

It is now possible to write binary data stored in words at the host directly to the NT631/NT631C. This makes data conversion by a program at the host unnecessary, reducing the load on the host.

Any quadrupled characters are displayed with a 32 dot high-definition font.

By using the system installer supplied with the Support Tool (Type NT- ZJCAT1-EV4), the system program at the NT631/NT631C can be changed easily from a personal computer.

The NT631/NT631C meets UL/CSA standards and EC directives.

Compatible with Sequencers in the following series: Mitsubishi A-series (Calculator Link) and FX-series (Programming Console), Allen-Bradley SLC 500 Series, GE Fanuc 90-20 and 90-30 Series, and Siemens S7-300 and S7-400 Series. Specialized system programs can be installed that allow the NT631/ NT631C to be controlled from other companies’ Sequencers.

Up to 3 windows can be displayed simultaneously in the normal screen. A 9- word window control area has been allocated to the host; the contents of these 9 words can be changed from the Host to open, close, and move windows.

The V2 versions are compatible with the high-speed 1:N NT Link as well as the earlier standard 1:N NT Link.

Operands (values referenced by formula) can be registered to allow the PT to perform calculations automatically and write the results of those calculations to numeral memory tables or words in the host.

The new device monitor function can be used to change the PLC’s operating mode or display/change values in the PLC’s memory areas. The present values (PVs) of several words can be listed with the device monitor.

PT operations and inputs can be disabled from the PLC if interlock bits have been allocated in the PLC for the corresponding PT touch switches, numeric inputs, or string inputs.

The following displays can be performed with lamp or touch switch labels:

•Display several lines of labels.

•Switch the display between different labels when OFF and ON.

•Display the numeral memory table contents as labels.

•Display the string memory table contents as labels.

The word configuration of the PT status control area and PT status notify area can be set to emulate those of the NT30/NT30C or NT620S/NT620C/ NT625C; this mode is called NT30/620 compatible mode.

When the PT is operating in NT30/620 compatible mode, it will be equivalent to an NT30/NT30C or NT620S/NT620C/NT625C in the functions listed below. The PT retains full V2 functionality in all functions other than the ones listed below. Refer to Appendix C in the NT31/NT31C/NT631/NT631C Programmable Terminal Reference Manual for more details.

•Word configuration and functions of the PT status control area and PT status notify area

•Image/library codes

•Insertion of image/library data into character strings

Data areas in CS/CJ-series PLCs that were previously inaccessible can be accessed. The data areas listed below can be accessed (read/written).

All banks in the EM area, timer completion flags (TU), counter completion flags (CU), Work areas (WR), Task flags (TK), and the HR area.

You can set the data (numeric values) for multiple words in record units using the tabular elements on the PT screen, and write these settings in a single operation to words on the host (i.e., PLC or PT memory) using a touch switch operation on the PT Unit. Also, multiple words of numeric data can be read from the host in one operation. In this way, groups of parameter settings can be edited at the PT Unit, and written to or read from the host.

You can display the brightness and contrast adjustment screen using either the touch switch or commands from the host, even while the PT is in operation.

Functions of the NT631/NT631C

Section 1-2

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.

Displays

The NT631/NT631C can display various kinds of elements such as charac-

ters, numeric values, graphs, lamps, and touch switches, on a screen. The

screen data displayed by the NT631/NT631C are created by using the Sup-

port Tool at a personal computer.

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

Arc

Sector

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.

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.
