5-4 Memory Tables
The NT600S has the “character-string memory table” for the character data and
the “numeral memory table” for numeric data which can be written and updated by
the PC/Host.
The contents of the memory tables can be set by using the support tool when dis-
playing the memory tables on the screen or by editing the table.
5-4-1 Character-String Memory Table
The character-string memory table is an NT600S internal memory used to store
the character data. Up to 256 character-string memory tables can be used, and up
to 20 full size characters (40 bytes) can be stored in one memory table. The char-
acter-string memory tables at up to 50 positions can be registered in one screen.
Displaying a Character-string
The character-string memory tables are registered with table numbers 0 to 255.
When creating the screen data by using the support tool, set the position on the
screen to display a character-string and also set a character-string number to be
displayed.
When the NT600S is operated, the screen displays the contents of the character-
string memory table.
In the direct connection of Ver. 5, it is possible to display the character-string by
designating the number of the character-string memory table using the numeric
memory table instead of directly changing the contents of the character-string
memory table. (indirect designation)
For the procedure for changing the character-string in the table, refer to “Changing
Displayed Numerals or Character Strings (Changing the Contents of Allocated
Words)” (page 170, 172) or “Write Character-string Memory Table” (page 208).
If the RS-232C communication is used, it is possible to display the character-string
by the Host instruction disregarding of the screen presently displayed (terminal
function). Refer to “Specify Displayed Characters” (page 225).
Characters and Figures Which can be Displayed
The power of expression of the screen can be increased by giving various attrib-
utes such as the enlarged or reverse display to the characters of the character-
string memory table.
The character attributes can be set in the edit screen when creating the screen
data by using the support tool.
The following types of characters can be displayed on the NT600S:
