Lamp Attributes
The NT20S has the "lamp" function used to simply display the PC bit status.
This section describes the lamps which can be displayed.
The lamp display status (lit (flashing) or unlit) can be changed by instructions from
the PC/host.
For details on how to change the status of a currently displayed lamp, refer to
"Turning ON (lit) and OFF (unlit) the Lamps (Changing the Contents of Allocated
Bits)" on page 179, "Lamp and Touch Switch Display (Bit Specification)" on page
210, and "Lamp and Touch Switch Display (Number Specification)" on page 210.
The lamps are the graphic areas whose method of display can be changed by us-
ing the PC. Available display methods are "lit", "unlit", and "flash". Up to 128 lamps
can be registered in one screen.
The display status (lit, unlit, and flashing) which are registered when creating the
screen data can be switched according to the ON/OFF of the PC bit status.
