These two items turn results from the activated bar code detection into conditions.
Any Barcode
will accept all bar codes detected, whereas
Barcode ==..
will filter de-
tection results according to a value or value range specified. The formatting of value
is the same as for the Trigger Value ( see chapter 4.6.4.4.4. ) used during bar code configuration.
Counter _ ==..
turns a specific count into a condition. As shown in the graphic at the
top of this section, in order to use this as a trigger for an action, you will additional-
ly need to specify a counter, as the reference item, plus the desired count, as the value.
This item uses a positive result from the Double Feed Detection, as a condition.
These three entries may be used as conditions if a Dual Input Hopper is installed.
Feeder
will trigger whenever the input tray is switched,
Left Input
and
Right Input
will
trigger whenever the respective tray is activated.
The last two items will trigger whenever the document length falls below a certain
value (
Shorter Than
) or exceeds a certain value (
Longer Than
). The values used are spe-
cified through respective fields ( see chapter 4.6.4.2.7. ) in menu item
Control Settings
.
4.6.8.4. Complex Rules
As indicated above, rules may also be defined as
Complex
, in the rule definition screen. Complex rules
are used whenever several conditions need to be simultaneously met, for an action to take place. Up
to four conditions may be combined in a complex rule. Such conditions are initially defined as indi-
vidual,
Simple
Rules, but without an Action specified. If a Simple Rule with an Action is inadvertently
added to a Complex Rule, this will result in a consistency error.
Please consider the following example, which will illustrate a typical application for a Complex Rule:
A document pile for a scan project contains forms of varying lengths. Documents of approx. 150 mm
in length are supposed to be ejected into the rear bin, whereas shorter or longer documents are not.
In order to achieve this, limits of
160 mm and 140 mm are entered into the fields for
Shorter Than
and
Longer Than
( see chapter 4.6.4.2.7. ), respectively. Next, two self-defined rules are created ( named shorter
160
and
longer 140
), which are assigned conditions
Shorter Than
and
Longer Than
,
respectively, but are not assigned any actions. After saving them, these rules are
highlighted orange, in the rules list, because they have not yet been assigned to
a complex rule and are also not usable in their
own right, since they contain no action. Next,
a new rule is created ( named
own rear at 150
),
which is defined as
Complex
and assigned action
rear1
. Besides
No Condition
, the drop-down lists
for Condition will also offer all self-defined rules.
Both rules created earlier need to be selected as
the first two conditions. After saving this new
Complex Rule, rules
shorter 160
and
longer 140
will
have been successfully assigned and are no longer
highlighted orange. If this Complex Rule is utilized
in a scan-profile, all documents with a length bet-
ween 140 mm and 160 mm ( i.e. approx. 150 mm )
are ejected into the rear bin, since this is the range where both conditions overlap and simultaneously
become true.
