Data Elements
Name
Project All data, such as screen data and settings files, are created in units called projects.
A screen number is allocated to each screen and up to 4,000 screens can be created in each
Screen
project.
Sheets are screens that can be displayed in layers on normal screens. Sheets are useful when
Sheets the same images are to be displayed on more than one screen. Up to 32 sheets can be created
in each project.
Functional objects include buttons, lamps, numeral display and input objects, and string display
Functional
and input objects. Various screens can be created by setting the properties for each functional
Objects
object in the dialog boxes. Up to 1,024 functional objects can be used in one screen. (See note.)
Fixed objects are unlike functional objects in that they do not have monitor or input functions.
Fixed Although fixed objects can be set to flicker, they are otherwise displayed in a constant state.
Objects 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.)
The table function combines multiple functional objects into a single table format. Up to 256
Tables
functional objects can be combined into one table.
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-
Frames 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.
A background is a graphic screen that is displayed as the background of another screen.
Back-
grounds
Note: Backgrounds cannot be set for sheets.
Text Text files are used to browse character stings and screen file names displayed by list selection
objects, text objects, and bitmap objects.
Files
The flicker settings make fixed and functional objects flicker at specified intervals. Ten flicker
Flicker
types can be registered for each screen. For fixed objects, a selection can be made from three
settings
prepared flicker types.
This function asks for a password to be entered when functional objects are manipulated.
Password
A password of up to 16 characters can be set.
settings
Up to 5 passwords can be set for one project.
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
Data log
group.
settings
Up to 50 addresses can be set for constant logging.
This function performs mutually exclusive operations when buttons are pressed. If the same
Group
group number is set to multiple buttons, this function ensures that only one button can be turned
specifica-
ON. Groups 1 to 16 can be selected for one screen. The group specification function is used with
tions
ON/OFF buttons.
Numeral This function facilitates unit name display and scale conversion display for numeral display ob-
unit and
jects. Up to 1,000 numeral unit and scale settings can be made for one project.

settings
This function displays a confirmation message when data is written to functional objects. Any
Dialog
confirmation message can be set. Up to 200 write confirmation messages can be set for one
settings
project.
This function always monitors signals registered as alarms or events and records any value
Alarm and
change (e.g., from OFF to ON.) The registered data can be displayed simply in the alarm and
event
event objects or can be displayed in a list.
settings
Up to 5,000 alarms and events can be registered for one project.
Data Block This function writes and reads preset data to a PLC.
setting
This function registers a communications address to be displayed in the broken-line graph. When a bro-
Broken-line
ken-line graph group has been set, the new graph can be displayed over the existing graph display.

setting
Up to 16 groups can be registered. Up to 256 communications addresses can be set in each group.
Symbol
This function manages the variables that are registered in a project. Variables can be registered, changed,

and deleted.
