Functions of the NT631/NT631C Section 1-2
1-2-5 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.
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.
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 regis-
tered 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 dis-
played at any position on the screen.
Since it is generated by combining graphics, library data has a small data
size.
