6.5 Menu Tree and Data Points
All data points (setting values, signals, measured values, etc.) are selected using
a menu tree. When navigating through the menu tree, the first two lines of the
LC-Display always show the branch of the menu tree that is active, as selected
by the user. The data points are found at the lowest level of a menu tree branch
and they are displayed either with their plain text description or in numerically
encoded form, as selected by the user. The value associated with the selected
data point, its meaning, and its unit of measurement are displayed in the line
below.
