Section 5-2
When it is necessary to display changing data such as monitored data of words in
the PC, use the numeral and character-string memory tables. This must be used
to change the display contents (contents of memory table and words).
Procedure 1. Use the support tool to allocate the numeral and character-string memory
tables to the PC memory.
2. Register the memory tables for the numerals and character-strings to be dis-
played when creating the screen data by using the support tool.
To display a character-string, use “character display” and specify the charac-
ter-string memory table by using the support tool.
To display numerals, use “numeral display” and specify the numeral memory
table by using the support tool.
3. Create a PC program to write the contents of numerals and character-strings
to be displayed on the NT600S to the PC words.

Important points when writing a character-string
If the character font for character-strings displayed on the NT600S screen is set
as half height and a normal character-string is written after displaying a 2-byte
code (mark), part of the mark will remain displayed, as shown below.

      
In this case, first write a 2-byte code (FF20 to FF5F) for which nothing is regis-
tered, then write a normal-size character-string.
Application Example of the Numeral Memory Tables Allocated to the PC Words
This example gives the procedure to directly display the contents of the words allo-
cated as the numeral memory tables in the PC memory. The NT600S screen dis-
play will change as the contents of the PC word change.
