8-5 Changing Numeral and Character String Display
This section describes the procedure(s) for changing the contents of the numeral
and character string memory tables which are allocated to the host and also the
procedure for changing the display on the NT631/NT631C by operation at the
host.
For the procedure for displaying the contents of the numeral and character string
memory tables at the NT631/NT631C, refer to 7-8 “Numeral Display” (page 348)
and 7-9 “Character String Display” (page 356).
8-5-1 Changing Numeric Values and Character Strings
The NT631/NT631C provides the following methods for changing the contents in
the numeral and character string memory tables.
- Changing the contents of the allocated word of a numeral memory table
- Changing the contents of the allocated word of a character string memory
table
- Copying the contents by operation at the PT status control area
- Pressing a touch switch which has the “Copy Setting” function
Reference It is possible to input the data to numeral memory tables and character string
memory tables by operation at the NT631/NT631C using the numeral setting func-
tion and the character string setting function.
For details of this operation, refer to 8-7 “Input of Numeric Values and Character
Strings” (page 505).
Changing the Contents of the Allocated Word of a Numeral Memory Table
By allocating a numeral table to a word in the host, it is easy to reflect changes
made at the word in the host to the numeral memory table.
With this method, however, only the contents of the allocated words of memory
tables being used for display on the current screen of the NT631/NT631C can be
read out. Contents of an allocated word which is not related to the display are not
read out.
