Library data are combinations of fixed display graphics registered as a single
graphic. They are registered in advance and as many as required can be dis-
played at any position on the screen.
Since it is generated by combining graphics, library data has a small data size.
Mark Image data Library data
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 nor-
mal 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.
