Permanently defined parameters/device parameters
On the PROFINET-IO, parameters may be stored in modules or may be defined permanently
in a PROFINET-IO participant.
The permanently defined parameters are called "common" parameters or device-specific
parameters, depending on the configuration tool.
These parameters must always be present. They are defined outside of the configuration
modules and are permanently anchored in the telegram header.
In Simatic Manager, the permanently defined parameters are set via object properties of
the device. The module parameters are set via the module list of the selected device. By
selecting the project properties of a module, the respective parameters may be set if
required.
The following list contains the device parameters that are permanently defined in the
MA 248

(DAP Slot 0/Subslot 0) but are configurable. These parameters always exist and
are available independent of the modules.
