Parameters
5.8.3.1.9
Certain numb. of new labels
If the N
EW
LABEL
value is selected for the
parameter, the
parameter can be used to define the minimum number of codes (labels) that have to
be read before a code is output again. This can be used to ensure that the same object is
not read multiple times.
5.8.3.1.10
Label timeout active
parameter is activated, you can define the time period after
which an identical code (label) may be output again.
5.8.3.1.11
Timeout
If the E
ND
OF
LABEL
parameter, you can use the
parameter to define the period after which a code is output again.
The unit can be selected in the
5.8.4
Evaluation conditions
Conditions that are checked by the device at each reading gate are defined on the
tab. If defined conditions are fulfilled, specific actions can be perfor-
med by the device – for example, setting an output signal, ending a reading gate, or output-
ting an image or a particular data string.
Evaluation conditions can be used to define situations that serve as reference points for fle-
xible process control and data processing in the device software. The use of evaluation con-
ditions shifts the complexity of control tasks from the external controls (PLCs) into the code
reader, meaning costs are reduced.
