Copying the Memory Table
The following describes the procedure to change displayed numerals or character
-strings by copying the contents of the memory table.
Numerals and character-strings can be changed also by changing the contents of
the allocated words. Refer to “Changing displayed numerals or character -strings”
explained before.
To change the numerals or character-strings displayed on the NT11S, copy the
data between the numeral or character-string memory tables by using the “copy
memory table setting” of the PT status control area.

Write a memory table number etc. to the copy memory table setting area in the PT
status control area in the PC memory. Data will be copied between the memory
tables in the NT11S and the displayed value will change accordingly.
This procedure is convenient to switch predetermined values or character-strings
according to the situation. By preparing several units of contents, various con-
tents can be displayed by switching them to suit the situation.
