THE INPUT SCREEN 28
Input The extent of the labelling is specified here. The given values refer to the
marked area.
System
Start value Any numerical value with which the labelling is to begin.
End value
Any numerical value with which the labelling is to finish
Prefix One or more alphanumeric characters added before the number
Suffix One or more alphanumeric characters added after the number
Block Another numeral which allows a block-type allocation of the labelling text. This figure defines the
start value for the block-type allocation.
Decimal 0-9 The start value must lie between 0 and 9. The decimal system is used for counting.
Examples: step=1
?
start value=8, end value=2
?
sequence 8, 7, 6, 5, 4, 3, 2
step=1
?
start value=2, end value=8
?
sequence 2, 3, 4, 5, 6, 7, 8
Octal 0-7 The start value must lie between 0 and 7, i.e. octal notation.
Hex 0-F The start value must lie between 0-9 and A-F, i.e. hexadecimal notation.
Alphanumeric An alphanumeric character can be entered in the base section. Alphanumeric characters are, for
example, 1, 2, 3,...7, 8, 9 or a, b, c,...x, y, z or A, B, C,...X, Y, Z, whereas, for example, 11, 123
or aa, abc or AA, ABC are not (these are character strings). Entering an upper- or lower-case
letter means that the following values are also upper- or lower-case letters.
Example 1: step=1
?
start value=X, end value=B
?
sequence X, W, V,...D, C, B step=1
?
start
value=B, end value=X
?
sequence B, C, D,...V, W, X
Example 2: step=1
?
start value=x, end value=b
?
sequence x, w, v,...d, c, b step=1
?
start
value=b, end value=x
?
sequence b, c, d,...v, w, x
Character
string
Several alphanumeric characters may be entered in the Source section. Only an entry in the
"Start value" field is possible; all the other fields in the Source section are inactive. Every high-
lighted marker is provided with the same text. Examples of character strings: 1234 or abcd or
ABCD or 1a2Bd3.
PLC This mode is used when the markers are to be provided with PLC-type labelling. When activat-
ing this option, the program provides an example of how PLC (Programmable Logic Control)
labelling is arranged.
