9.3
Definition of an object in the Web Editor
■ An object is a static text component, a multi-line label, a line, a rectangle, an
ellipse, a polygon, an edit field, a button, or a bar chart. Macros contain many
objects (an offline trend contains 44 objects).
9.4 Handling
■ Touchscreen: The base material of the touchscreen is glass. For this reason,
you should therefore not touch the screen with a screwdriver or hard objects,
which could damage the screen. Use only a finger or special input stylus for
operation.
■ In addition: use the right tool for a hardware reset. Do not use a paperclip or
pin, but rather push the microswitch carefully with a Ø 3 mm drill bit.

Some rules regarding gif images
■ The three timestamps on the MB panel’s graphical display are:
● Repaint video cache
● Decompression in the video cache in case of URL jump and after startup
(almost linear with the number of pixels). See "9.5.3
Gif files: analysis/calculation" on page 9-4
● File transfer time via the link if not local.
■ If the total size of the gif files is the same, one large image (max. 512 Kbytes) is
better than two smaller ones.
Recommended max. size 798 × 598 pixels (one pixel remains free all-around).
■ It is better to use the same image multiple times in the same project, because
it then has to be transferred only once, decompressed and stored in the video
cache. Place it, for example, in the teq file for the general background.
