Starting up the device - PROFINET interface

Configure the hardware of the control:
Add the CML 700i to your PROFINET hardware configuration.
Assign a unique device name. If necessary, check the automatically assigned IP address.
Transfer the PROFINET configuration to the control.
Following successful transfer, the following activities take place automatically:
• Check of device names
• The control distributes the IP addresses on the basis of the unique device names.
Without configured topology, the IP address is assigned to named devices only.
• Establishment of a connection between the IO Controller and configured IO devices
• Cyclical data exchange
Device naming
PROFINET defines the "naming of the device" as the creation of a name-based relationship for a
PROFINET device.
Set the device name.
The device name is normally assigned using the configuration tool, e.g. in the SIMATIC manager using
the

function.
The PROFINET device has a unique MAC address that is part of the factory settings. The MAC address
may be found on the name plate of the CML 700i. Multiple CML 700i devices can be distinguished by
the MAC addresses displayed.
This information is used to assign a unique, plant-specific device name (“NameOfStation”) to the device
via the "Discovery and Configuration Protocol (DCP)".
Every time the system is started up, PROFINET uses the DCP protocol for the IP address assignment,
provided the IO-device is located in the same subnet.
Assign the device names to the configured IO devices.
Select the CML 700i using its MAC address. The unique device name (which must match the name in
the HW Config) is then assigned to the CML 700i.
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
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
CML 700i device model. This is also reflected in the file name.
In the GSDML file, all data necessary for operating the CML 730i 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 CML 700i is defined via 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 CML 700i 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. The default settings of the CML 700i can be found in the
module descriptions.
Participants that have not been "named" cannot be contacted yet at this point in time!
