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 complex PROFINET device model, the XML-based GS-
DML was introduced. In the following, the terms "GSD" or "GSD file" always refer to the GS-
DML-based format. The GSDML file can support an arbitrary number of languages in one file.
Every GSDML file contains a version of the DDLS 548i device model. This is also reflected in
the file name.
In the GSDML file, all data necessary for operating the DDLS 548i is described in modules: In-
put and output data, 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. The file is not changed by the system either.
The functionality of the DDLS 548i is defined via modules in the GSDML file. A user-specific
configuration tool is used during PLC program creation to integrate the required modules and
configure them appropriately for their respective use.
When operating the DDLS 548i on the PROFINET, all input/output data is occupied with default
values. If this input/output data is not changed by the user, the device operates with the default
settings set by Leuze electronic on delivery. You can find the default settings of the DDLS 548i
in the module descriptions.
NOTICE
GSDML file name structure
The file name of the GSDML file is constructed according to the following rule:
GSDML-[GSDML-schema-version]-Leuze-DDLS548i-[date].xml
[GSDML schema version] = Version identifier of the GSDML schema version used, e.g., V2.31
[Date] = Release date of the GSDML file in the format yyyymmdd
This date also stands for the release date of the file.
Example: GSDML-V2.31-LEUZE-DDLS548i
Ä Configure the hardware of the S7 PLC:
• Insert the DDLS 548i in your project. The PROFINET system is configured with the help of the hard-
ware configuration (HW-Config) of the SIMATIC Manager.
• Assign an IP address a unique device name.
Ä 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
NOTICE
Participants that have not been "named" cannot be contacted yet at this point in time!
Device naming
PROFINET defines the "naming of the device" as the creation of a name-based relationship for a
PROFINET device.
Ä Set the device name.
• The PROFINET device has a unique MAC address that is part of the factory settings. The MAC ad-
dress may be found on the name plate of the DDLS 548i. Multiple DDLS 548i devices are distinguished
by the displayed MAC addresses.
