8.6.2 DAP module – permanently defined parameters
On the PROFINET, parameters may be stored in modules or may be defined permanently in a PROFINET
participant. Depending on the configuration tool, the permanently defined but adjustable parameters are
called “common” parameters or device-specific parameters.
The common parameters must always be present. They are defined outside configuration modules and
are thus connected to the base module (DAP: Device Access Point) that is addressed via slot 0/subslot 0.
The following list contains the device parameters that are permanently defined in the BPS (DAP Slot 0/
Subslot 0) but are configurable. These parameters always exist and are available independent of the
modules.
Common parameters/device-specific parameters (DAP: Device Access Point):

Each PROFINET device must have a DAP module. The DAP module represents the communi

cation access point to the BPS.
The module contains device-specific parameters, but no input data and no output data.
