Functions of the NT31/NT31C Section 1-2
Lamps These are graphics whose display status changes in accordance with the
states of bits at the host. Squares, circles, sectors and polygons can be used
for lamps (normal (standard) lamps). In accordance with the status of the host
bit, they can be lit (displayed in reverse video) or flashed (repeated alternation
between normal and reverse video display states).
Lamps can also display different image/library data for the ON and OFF states
of the host bit (such lamps are called image/library lamps).
There are four standard lamp labels: fixed display character strings, ON/OFF
switching character strings, numeral displays, and character string displays.
When fixed display character strings or ON/OFF switching character strings
are used, several lines of labels can be displayed.
