S External Frame
This attribute can be set to determine whether or not a boundary line of the
Lamp is displayed. When an external frame is set to not be displayed, only the
guide display characters of the lamp are displayed when the lamp is not ON (or
flashing). When the guide display character is not set, nothing is displayed.
S ON/Flashing
When lamp is ON by an instruction from the PC, its displaying state can be spe-
cified out of ON (inverse illumination) or Flashing (inverse flashing).
S Color Display (NT30C Only)
External frame color (in case of color display): 8 colors
OFF color: 8 colors or transparent
ON/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.
S Guide Display
Guide display character can be attached to the lamp. Attributes of the guide
display character are the same as that of character display. Refer to Charac-
ters and Figures that can be Displayed (page 137).
S 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 entry or charac-
ter string memory table entry in conjunction with illumination of lamp. However,
depending on a timing of ON of normal lamp and memory table entry update,
the result of indication differs as shown in the examples below. Be careful when
creating a control program.
