Displaying and Referencing Character String Memory Table Contents
Memory Tables and Bar Graphs
Memory Tables and Bar Graphs
Since the character-string memory tables can be allocated to the words in the PC,
the PC can write data to the character-string memory tables or the initial values
can be set when creating the screen data.
Automatic updating is performed to ensure that the currently displayed NT20S
character string memory table contents and PC word contents always match each
other.
There are two methods for referencing character string memory tables used for
character string display, as follows:
S Direct specification
S Indirect specification (with Ver.5 direct connection only)
- Direct specification
- Indirect specification (with Ver.5 direct connection only)
Direct specification is a method of specification in which the contents of dis-
played memory tables are directly correlated with the contents of the allocated
words.
In indirect specification, even if the displayed data is a character string, the dis-
play is correlated with a numeral memory table. The contents (numerical value)
of this numeral memory table are regarded as a character string memory table
number and the contents of the table with this number are displayed.
Up to 50 numeral displays and 50 character string displays can be specified on
one screen by using indirect specification.
