Working method of the device
The CCD bar code reader CLP 100 detects bar codes in an illuminated scan field (scan line)
and decodes the bar codes. The CLP 100 transmits this data via the serial host interface to
a host/PC for further processing. Refer to
Figure
for an overview of the functionality of
the CLP 100.
The CLP 100 derives useful data for diagnostics from the reading processes. The quality of
the reading data can be checked in the diagnosis mode.
The CLP 100 requires suitable pulsing (triggering) in order to start a reading process when
there is an object in the reading area. This results in a time window for the reading process
being opened in the CLP 100. Triggering is carried out either with an external sensor or with
a command string via the host interface. Both options are active in the default setting.
The switching input ("Sensor" input) informs the CLP 100 when it must start a reading
process. The switching output ("Result" output) can have result functions assigned to them
and triggers external devices such as, for example, a PLC input.
3.3
Display and operating elements
The CLP 100 is operated or parameterized via the host interface by using the CLP Setup
PC software or with command strings. The CLP 100 is adapted to various applications by
means of parameterization. The CLP Setup software is used, for example, to carry out the
following settings:
•
Configuration of the code types to be read
•
Read, evaluation and output properties
•
Communication parameters of the host interface
•
Structure of the data output strings of the host interface
•
Function of the auxiliary interface (terminal interface)
describes the installation and handling of the CLP Setup software.
The procedure for parameterizing the CLP 100 with the software is explained in
