Parameters
5.8.3.1.9 Certain numb. of new labels
If the N
EW LABEL value is selected for the Output time parameter, the Certain numb. of new
labels 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
If the 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 value is selected for the Output time parameter, you can use the Timeout
parameter to define the period after which a code is output again.
The unit can be selected in the Output delay parameter.
5.8.4 Evaluation conditions
Conditions that are checked by the device at each reading gate are defined on the
Evaluation conditions 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.
5.8.4.1 Conditions for Good Read
The Conditions for Good Read selection list is used to define the condition for which a rea-
ding is classed as a G
OOD READ.
• U
SE MIN./MAX. NUMBER OF CODES: Depending on the configuration of parameters Check min.
number of valid codes and Check max. number of valid codes a reading is classed as a G
OOD
R
EAD if the number of read codes lies between the specified minimum value and the speci-
fied maximum value.
• C
ONDITION MATCH1: Reading is rated as a GOOD READ if the read code corresponds to
M
ATCHCODE MATCH 1.
• C
ONDITION MULTCODES1: Reading is rated as a GOOD READ if the number of read codes cor-
responds to the required number.
• C
ONDITION TEACHIN1: Reading is rated as a GOOD READ if the read code corresponds to
M
ATCHCODE TEACH-IN 1.
• C
ONDITION TEACHIN2: Reading is rated as a GOOD READ if the read code corresponds to
M
ATCHCODE TEACH-IN 2.
