4-4-2 Numeral Memory Table
The numeral memory table is an NT620S/620C internal memory used to store
the numeral data. Up to 1000 numeral memory tables can be used, and up to 8
digits (4 bytes) of numeral data (including signs) can be stored in one numeral
memory table. The numeral memory tables at up to 50 positions can be regis-
tered in one screen.
Number of Numeral Memory Tables
Set the number of numeral memory tables in the support tool’s “system memory”.
512:
Sets the number of numeral memory tables to 512
1000:
Sets the number of numeral memory tables to 1000.
The difference between setting 1000 numeral memory tables and 512 numeral
memory tables in terms of the memory capacity required for screens is 4880 by-
tes.
Displaying a Numeral
The numeral memory tables are registered with table numbers 0 to 999.
When creating the screen data by using the support tool, set the position on the
screen to display a numeral and also set a numeral number to be displayed.
When the NT620S/620C is operated, the screen displays the contents of the nu-
meral memory table. For the actual method used to modify a currently displayed
numerical value, see “Changing Displayed Numerals or Character-Strings
(Changing the Contents of Allocated Words)” (page 204).
Numeral memory table numbers 247 through 255 are used for the clock function.
They cannot be used for other applications. For details on the clock function, see
Section 5-6 “Clock Function” (page 229).
Numerals 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 numerals of the numeral
memory table.
The numeral attributes can be set in the edit screen when creating the screen
data by using the support tool.
