• Difference between image data and library data
Image data can take any form for it is composed of dots, but library data can
only be created by assembling fixed display text and graphics.
Since only drawing information for characters and graphics is registered for
library data, library data requires little memory area in comparison with
image data, which requires all the dots to be displayed on the screen to be
registered as data.
Another difference is that flash and inverse display are not possible for
image data, but library data can be displayed in these modes in accordance
with the display attributes of the registered elements. The timing of the flash-
ing is the same for all elements.
• It is possible to specify different image/library data for the graphic displayed
when a lamp (image/library lamp) is ON and OFF (page 103).
• It is possible to specify different image/library data for each message displayed
for the alarm list/alarm history function (page 173).
• Library data elements overlap with other fixed display elements in accordance
with the order in which they were displayed. However, the way in which they
overlap can be changed with the Support Tool.
