Functions of the NT631/NT631C Section 1-2
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
Resume function
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
Device Monitor function
System program install function
Screen display history function/alarm history function
Trend graph logging function and background function
Mathematical function
Functions relating to data input
Input by touch switches
Pop-up window function
Numeral/character string setting function
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
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.
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.
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.
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.
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.
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).
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.
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).
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.
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.
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 data created using the Support Tool at a personal computer can be transferred and stored in the built-in screen
data memory.
