Changing Displayed Numerals or Character Strings

The following describes the procedure to change displayed numerals or character
-strings by changing the contents of the allocated words.
Numerals and character-strings can be changed also by making a copy of the
memory tables. Refer to “Copying the memory table” explained later.
To change the numerals or character-strings displayed on the NT11S, make
changes with the numeral or character-string memory table. To make changes
with the numeral or character-string memory table of the NT11S, change the con-
tents of words by the PC.

to change the display contents (contents of memory table and words).
