Overview
The animation table offers two different modes (/) to animate strings.
Normally only the first 16 characters of a string are animated (modified).
The reason for this restriction is that for animation handling a PLC reserves a buffer.
The size of this buffer is limited and the animation of complete strings can exceed the size of the buffer easily.
Extended Strings
The animation table can animate more than 16 characters of a string.
At the right side of the command zone area there is the checkbox 
(Extended Strings).
It can be used to activate the mode .
Presentation
The number of characters to be animated in the mode can be set in the properties of the animation table (see Animation Table Properties).
NOTE: Using this feature you should keep in mind that the animation of
big strings can reduce the number of sections and animation tables
which can be animated at the same time.
