• 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.
Ä
Assign the device names to the configured IO devices.
• Select the DDLS 548i using the MAC address.
• The DDLS 548i is then assigned the unique device name. The device name must match the device
name configured in the HW Config.
Ä
Assign the IP address to the MAC address (individual device name).
• At this point, assign another IP address (suggested by the PLC), a subnet mask and, if required, a
router address, and assign this data to the named participant (device name).
• From now on, and when programming, only the unique device name (max. 240 characters) is used.
Ä
After completing the configuration phase, check the device names that have been assigned.
NOTICE
Assign unique device name!
Ä
Ensure that the device names are unique and that all participants are located in the same
subnet.

NOTICE
Overwriting of data by PLC!
Ä
Note that the PLC overwrites the data set in the
Service
operating mode of the webConfig
tool. When switching the webConfig operating mode from
Service
to
Process
, all service set-
tings are overwritten by the GSDML modules of the control or its default values.
Ä
During the configuration phase, the DDLS 548i receives data telegrams from the IO con-
troller (master). Before the data telegrams are evaluated and the respective settings are
made, all interface-specific settings are reset to default values. This ensures that the set-
tings of modules that are not selected are set to the default values.
NOTICE
You can find the default values of the DDLS 548i in the module descriptions.
7.4.1
Overview of the modules
The module definitions begin with the Device Access Point (DAP) module. A DAP determines the funda-
mental properties of the IO device. In the GSDML file, the possibilities of the IO device and the possible
modules with their properties are thereby described.
