4.2.1 Entering Numerical Values
In fields that allow the operator to enter a numerical value, you enter the nu-
merical value character by character using the keypad on the system key-
board.
If there is a value in the field already, it is cleared completely from the field
when the first character is entered. Once input has been started, you cannot
exit from the field until the input has been entered or canceled.
In numerical fields, input initially is normally right-justified . Digits that
have already been entered are moved to the left (pocket-calculator format).
Exception:
Input fields for variables in KM format – for instance, when calling the PU
functions STATUS/FORCE VAR – are changed to left-justified . When input
begins, the old value does not disappear from the display completely but its
bit pattern is overwritten one character at a time. You move the cursor in this
type of field by pressing an arrow key (
²
and
³
) with activated Shift Lock
mode.
You can configure limit values for numerical input fields. In this type of
field, a limit-value check takes place, i.e. the entered values are applied only
if they lie within the configured limits. If a value outside these limits is en-
tered, a system message is displayed and, after it has been canceled, the old
value is restored in the field.
If a numerical field has been configured with a certain number of decimal
places and too many have been entered, they are ignored; if too few have
been entered, the field is padded with zeroes.
