Keys Description
Unit keys Selects a unit and thus determine the absolute value, or changes the unit, i.e. trigger a recal-
culation without changing the absolute value. The function depends on the time at which the
UNIT key is used during parameter entry (see
​
chapter 4.4.5, "Working with Units
" , on page 63).
For unit-free values, the X1 key is equivalent to ENTER. It confirms the previous entry and
deactivates the input field.
_ Adds a blank in a character input field.
*... # Enters special characters. Toggles through the available characters if the key is pressed sev-
eral times in a row.
A <-> a Toggles between uppercase and lowercase characters.
A, B, C, D, E,
F Enters hexadecimal values. The letters assigned to the keys are automatically active when
an entry field with a hexadecimal value is active.

Increases (clockwise direction) or decreases (counter-clockwise direction) numeric
values at a defined step width in editing mode
●
Moves the cursor, e.g. to a function block in the block diagram
