Wildcards
There is an indicator which shows the current number of wildcards (19) and a
display field for inputs (20) . When you place the cursor in the display field a
keyboard for data inputs is displayed (21) . In the event of modifications of the
number or the kind of the wildcard character (23) the indicator (22) will be updated
immediately. In the job editor the defined <Wildcards> are shown as content of
the <Extern text: variable length> object (26) .
Wildcards for an <Extern Text:variable length> object have two functions:
1. The characters of the set wildcards represent the first character string that
will be displayed on the WYSIWYG display and printed. They will then be
replaced by the first received data.
2. Wildcards, together with the character offset, define the length of the input
buffer and therefore the maximum number of characters to be considered. If
there are more characters between the
<Start symbol> and the <End
symbol> than limited by the <Wildcards> settings only the defined
number of characters following the <Start symbol> will be used.
Character offset
With the character offset
(24)
you can define how many characters from the left
side of the received string will be ignored. You can set the character offset either
with the arrow keys of the display field
(24) or with the numeric keypad (25)
displayed when placing the cursor in the display field.
Example <Start symbol>, <End symbol>, <Wildcards>, <Character offset>:
Set start symbol: 65 = A
Set end symbol: 66 = B
Set wildcards: Displayed text:
Wildcards
= 9 characters = 9 wildcards
Set offset:
3

Result:
Due to the
<Start symbol> A the input buffer is filled starting with the transmitted
character A.
Due to the set <Offset> the first 3 characters of the received data are not used.
Due to the
<Wildcards>
only the first 9 characters of the remaining data are used.
Due to the <End symbol> B only all characters up to the B are used.
