BCL 504

TNT 35/7-24V
With the aid of the
CRT decoder
, barcodes can also be read without problem in other
demanding situations, such as with a large tilt angle (azimuth angle or even twist angle).

With the BCL 504
i
, configuration is generally performed with the aid of the GSD file.
The BCL 504
i
needs a suitable activation to start a read process as soon as an object is in
the reading field. This opens a time window ("reading gate") in the BCL 504
i
for the read
process during which the barcode reader has time to detect and decode a barcode.
In the basic setting, triggering takes place through an external reading cycle signal or via the
PROFIBUS. An alternative option for activation is the
autoReflAct
function.
Through the read operation, the BCL 504
i
collects additional useful pieces of data for diag-
nosis which can also be transmitted to the host. The quality of the read operation can be
inspected using the
alignment mode
which is integrated in the webConfig tool.
A multi-language display with buttons is used to operate the BCL 504
i
as well as for visual-
isation purposes. Two LEDs provide additional optical information on the current operating
state of the device.
The four freely configurable switching inputs/outputs "SWIO 1 … SWIO 4" can be assigned
various functions and control e.g. activation of the BCL 504
i
or external devices, such as a
PLC.
System, warning and error messages provide assistance in set-up/troubleshooting during
commissioning and read operation.
