PROFINET interface – basic configuration
Leuze electronic
BPS 348i
51
Configure the hardware of the S7 PLC:
Add the BPS to your project. The PROFINET system is configured with the help of the hardware con
-
figuration (HW-Config) of the SIMATIC Manager.
Assign an IP address a unique device name.
Transfer the PROFINET configuration to the IO Controller (S7 PLC).
Following successful transfer, the following activities take place automatically:
• Check of device names
• Assignment of the IP addresses that were configured in the HW Config to the IO devices
• Establishment of a connection between the IO Controller and configured IO devices
• Cyclical data exchange
Alternatively, the GSDML file can be loaded from the BPS with the webConfig tool (see
chapter 9):
HOME > INSTALLATION > GSDML file
The GSDML file stored in the BPS is always compatible with the firmware version of the BPS.
General information on the GSDML file
The term GSD (Generic Station Description) stands for the textual description of a PROFINET
device model. For the description of the more complex PROFINET device model, the XML-based
GSDML (Generic Station Description Markup Language) was introduced. In the following, the
terms “GSD” or “GSD file” always refer to the GSDML-based format. The GSDML file can support
an arbitrary number of languages in one file. Every GSDML file contains a version of the BPS
device model. This is also reflected in the file name.
In the GSDML file, all data necessary for operating the BPS is described in modules: Input and
output data, device parameters, definition of the control and status bits.
If parameters are changed in the project tool, for example, these changes are stored by the PLC
in the project, not in the GSDML file. The GSDML 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 BPS is defined via GSD parameter sets. The parameters and their func
-
tions are structured in the GSDML file using modules. 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 BPS on the PROFINET 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. The default settings of the BPS can be found in
the module descriptions.
GSDML file name structure
The file name of the GSDML file is constructed according to the following rule:
GSDML-[GSDML schema version]-Leuze-[item description]-[date].xml
[GSDML schema version] = Version identifier of the GSDML schema version used, e.g., V2.2
[Date] = Release date of the GSDML file in the format yyyymmdd.
This date also stands for the release date of the file.
Example: GSDML-V2.2-Leuze-BPS348i-20131003.xml
