Leuze BPS 348i - Module 24 - Reading Quality

Starting up the device – Basic configuration
Leuze electronic GmbH + Co. KG BPS 348i 89
• A suitable measuring device must be used to determine the real (calibrated) length of one meter of
barcode tape (as printed). If, for example, one meter of tape corresponds to an actual (calibrated)
length of 1001.4mm, the value 10014 is entered in the Real length parameter of this module. The real
length is specified with a resolution of 1/10millimeters.
• To use the exact resolution, it is useful to measure a longer section of BCB and convert the deviation to
a length of one meter.
• The Range start parameter must be configured according to the real starting value of the used barcode
tape. If multiple, different BCBs are pieced together, the Range end parameter of the corrected section
of tape must also be configured. The entire BCB is corrected with the default value of 10,000,000 for
the range end.
• The module contains parameters (with parameter data length of 10bytes), but no input data and no
output data.

8.4.23 Module24–Reading quality
Module ID:1024 with submodule ID:1
• The module enables the Reading quality functionality for transmitting the BPS reading quality and for
configuring the parameters for warning threshold, error threshold and smoothing of the reading quality.
• By transmitting the reading quality, continuous monitoring is possible. The operator can immediately
see when the reading quality deteriorates due to wear or soiling.
NOTICE
Correct calculation of the reading quality
The evaluation of the reading quality is influenced by several factors, see chapter 4.5 "Evalua-
tion of the reading quality".
• The signaling of the reading quality is configured via the status information in module6 (see chapter
8.4.8 "Module6–Status and control") and via the switching output functions in module4 (see chapter
8.4.6 "Module4–Input/output IO1") or module5 (see chapter 8.4.7 "Module5–Input/output IO2").
• The module contains parameters (with parameter data length of 2bytes) and input data (with input data
length of 1byte), but no output data.
