Frame
Select whether or not the boundary line (frame) of the lamp display area is dis-
played. If the frame is not set, only the guide display message for the lamp is
displayed when the lamp is not lit (or flashing). If the guide display message is
not set, nothing is displayed.
•
Lit and flashing
Select whether the lamp is lit (reverse display) or flashing (reverse flashing)
when the lamp is turned ON by the PC.
•
Color display (NT620C only)
External frame color (in case of color display): 8 colors
OFF color: 8 colors or “transparent”
Lit/Flashing color: 8 colors
A part of external frame may be lost depending on a combination of external
frame color of the normal LAMP and OFF color or ON/Flashing color. This is
caused by the properties of the color LCD and does not indicate failure of
equipment. When part of the external frame is lost, change a combination of
colors.
•
Guide display message
Lamps can be displayed with the guide display messages.
The guide display message attributes are the same as that for the “character
display”. Refer to “Characters and Figures which can be Displayed” (page
134).
•
When a memory table display is overlapped with a normal lamp
The guide display character of the normal LAMP is a fixed character-string. In
order to change the guide display of the normal LAMP according to the circum-
stances, display the display area of the Numeral Memory Table or Character-
String Memory Table in conjunction with illumination of LAMP. However, de-
pending on a timing of ON of normal LAMP and Memory Table update, the re-
sult of indication differs as shown in the examples below. Be careful when
creating a control program.
