4-2 Section Outline of Functions
123
When a lamp, a touch switch and a graphic are to be displayed in specific colors,
part of the frames of the display elements may be invisible because of the com-
bination of the background, outline and filling colors. This is a phenomenon pe-
culiar to a color LCD, not a failure with the system.
In such a case, change the color combination.
4-2-3 Characters and Figures which can be Displayed
The NT620S/620C screen can display characters, figures, and other various ele-
ments.
This section describes the types and attributes of the characters and figures
which can be displayed and do not need to be changed at all.
For the settings, display, and use of the characters, numeric values, and graphs
which change according to the system operation status and other conditions, re-
fer to Section 4-4 “Memory Table” (page 133) and Section 5-2 “Memory Tables
and Graph” (page 198).
The power of expression of the screen can be increased by giving various attrib-
utes such as the enlarged or reverse display to the characters and figures.
The character and figure attributes can be set in the edit screen when creating
the screen data by using the support tool.
