Procedure for Creating and Using Library Data
The procedure for creating library data and registering them on a screen is de-
scribed briefly here. For details, refer to the NT-series Support Tool Version 4 for
Windows Operation Manual (V061-E1-).
Call the library editor.
Specify the library code.
Create the library data.
Specify a range.
Exit the library editor and register the library data.
Screen editing.
Register the created library data for display.
Indirect Specification
With indirect specification, specify a numeral memory table entry containing the
desired hexadecimal code. The PT treats the contents of the specified numeral
memory table entry as a library code and displays the corresponding library
image. This function is very convenient when you want to change displayed li-
braries.
Since library codes are hexadecimal, the Storage Type of the numeral memory
table entries that contain library codes must be set to binary and the values (li-
brary code numbers) stored in the table entries must be hexadecimal.

(Hex)
Restrictions
A maximum of 12,288 library data can be created for one screen data file: each
of the library data is assigned any required code within the range 1000 to
3FFF
H (image/library code range) so that it can be managed and specified.
A total of up to 256 image and library data elements (directly and indirectly spe-
cified) can be registered on one screen. (Same for window screen.) For over-
lapping screens comprising 8 child screens, the maximum is also 256.
The maximum number of elements that can be registered for one library data is
65,535.
The elements that can be registered in library data are the following fixed dis-
play elements: other elements cannot be registered.
Text, circles, arcs, sectors, polylines, polygons, rectangles, tiling, marks.
The codes used for library data are dedicated for image/library data use.
Library data cannot be included in character strings in the same way that
marks can, unless the PT is in NT20S or NT30/620 compatible mode.
