Tab. 148: Memory Required FB T
The D text display function block heavily depends on the configured display and input
elements and their texts. Every display and input element requires memory itself.
Moreover, the texts available for the element also require memory. Identical texts in
several display or input elements hardly require any additional memory due to com-
pression technology.
