General information on the GSD file
You can find the GSD file at
www.leuze.de -> Download -> identify -> Stationary and hand-held barcode readers
.
All data in modules required for operating the
BCL 504
i
is described in this file. These are
input and output data and device parameters for the functioning of the
BCL 504
i
and the
definition of the control and status bits.
If parameters are changed, e.g., in the project tool, these changes are stored on the PLC
side in the project, not in the GSD file. The GSD file is a certified and integral part of the
device and must not be changed manually. The file is not changed by the system either.
The functionality of the
BCL 504
i
is defined via GSD parameter sets. The parameters and
their functions are structured in the GSD file using module. A user-specific configuration tool
is used during PLC program creation to integrate the required modules and configure them
appropriately for their respective use. During operation of the
BCL 504
i
on the PROFIBUS,
all parameters are set to default values. If these parameters are not changed by the user,
the device functions with the default settings delivered by Leuze electronic.
For the default settings of the
BCL 504
i
, please refer to the following module descriptions.
Notice!
Please note that the set data is overwritten by the PLC!
Some controls make available a so-called "universal module". This module must not be ac-
tivated for the
BCL 504
i
!
From the perspective of the device, a distinction is made between PROFIBUS parameters
and internal parameters. PROFIBUS parameters are all parameters that can be changed via
the PROFIBUS and are described in the following modules. Internal parameters, on the
other hand, can only be changed via a service interface and retain their value even following
a PROFIBUS configuration.
During the configuration phase, the BCL receives a parameter telegram from the master.
Before this is evaluated and the respective parameter values are set, all PROFIBUS param-
eters are reset to default values. This ensures that the parameters of modules that are not
selected are set to the default values.
Notice!
This does not affect modules 1-4 for the code table extension. By default, all but the first
code table entry are locked. If "no code" is selected here, all subsequent code tables are
deactivated (see chapter 10.6.1 "Modules 1-4 – Code table extensions 1 to 4").
