NS Series Programming Manual
Data Elements
Name Contents
Project All data, such as screen data and settings files, are created in units called projects.
Screen
A screen number is allocated to each screen and up to 4,000 screens can be created in each
project.
Sheets
Sheets are screens that can be displayed in layers on normal screens. Sheets are useful when
the same images are to be displayed on more than one screen. Up to 32 sheets can be created
in each project.
Functional
Objects
Functional objects include buttons, lamps, numeral display and input objects, and string display
and input objects. Various screens can be created by setting the properties for each functional
object in the dialog boxes. Up to 1,024 functional objects can be used in one screen. (See note.)
Fixed
Objects
Fixed objects are unlike functional objects in that they do not have monitor or input functions.
Although fixed objects can be set to flicker, they are otherwise displayed in a constant state.
There are seven types of fixed objects: Lines, circles/ovals, arcs, sectors, polylines, polygons,
and rectangles. Up to 2,048 fixed objects can be used in one screen. (See note.)
Tables
The table function combines multiple functional objects into a single table format. Up to 256
functional objects can be combined into one table.
Frames
A frame object enables creating areas on a screen so that only part of the screen can be switched
to another page. Frames consist of more than one page, and the displayed contents of the func-
tional objects created on each page can be switched using the page switching function of the
frame. Up to 256 frame pages can be created for each frame. Up to 256 functional objects can be
used on each frame page. Up to 10 frames can be created for each screen.
Back-
grounds
A background is a graphic screen that is displayed as the background of another screen.
Note: Backgrounds cannot be set for sheets.
Text
Files
Text files are used to browse character stings and screen file names displayed by list selection
objects, text objects, and bitmap objects.
Flicker
settings
The flicker settings make fixed and functional objects flicker at specified intervals. Ten flicker
types can be registered for each screen. For fixed objects, a selection can be made from three
prepared flicker types.
Password
settings
This function asks for a password to be entered when functional objects are manipulated.
A password of up to 16 characters can be set.
Up to 5 passwords can be set for one project.
Data log
settings
Data log settings are used to register changes over time to the contents of an address. Settings
can be made for 100 groups, including the log timing. Up to 16 addresses can be set for one
group.
Up to 50 addresses can be set for constant logging.
Group
specifica-
tions
This function performs mutually exclusive operations when buttons are pressed. If the same
group number is set to multiple buttons, this function ensures that only one button can be turned
ON. Groups 1 to 16 can be selected for one screen. The group specification function is used with
ON/OFF buttons.
Numeral
unit and
scale
settings
This function facilitates unit name display and scale conversion display for numeral display ob-
jects. Up to 1,000 numeral unit and scale settings can be made for one project.
Dialog
settings
This function displays a confirmation message when data is written to functional objects. Any
confirmation message can be set. Up to 200 write confirmation messages can be set for one
project.
Alarm and
event
settings
This function always monitors signals registered as alarms or events and records any value
change (e.g., from OFF to ON.) The registered data can be displayed simply in the alarm and
event objects or can be displayed in a list.
Up to 5,000 alarms and events can be registered for one project.
Data Block
setting
This function writes and reads preset data to a PLC.
Broken-line
graph group
setting
This function registers a communications address to be displayed in the broken-line graph. When a bro-
ken-line graph group has been set, the new graph can be displayed over the existing graph display.
Up to 16 groups can be registered. Up to 256 communications addresses can be set in each group.
Symbol
table
This function manages the variables that are registered in a project. Variables can be registered, changed,
and deleted.
