6-2 Memory Tables and Bar Graph

This section describes allocation of the memory table to PC words, and changes to the contents of words necessary to display characters, numerals, and graphs by communicating with the PC using the Host link/NT link.

Reference For the functions relating to memory tables and bar graphs, refer to 4-4 Memory Tables (page 128) and 4-5 Bar Graphs (page 131), respectively.

Writing Words to the Character-String Memory Table

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.

NT600S

Display area where the character￿￿-string
	PC
memory table No. 2 is allocated
Character-string
memory table
	Word

The contents are the same while they are displayed.

Can be updated by the PC.

During the operation, the display contents are automatically updated so that the contents of the character-string memory table being displayed are the same as that of the PC word.

Displaying and Referencing Character String Memory Table Contents

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 NT600S 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:

-Direct specification

-Indirect specification (with Ver.5 direct connection only)
