Example of a System Structure using DP/EIB Link
How the DP/EIB Link Works
The data objects of the instabus EIB are mapped in the PROFIBUS I/O area.
The structuring of the PROFIBUS slave I/O area and the number of EIB data
objects with which the DP master communicates is decided by a selectable profile.
In total, five different profiles are available that allow the user to adapt the DP/EIB
link to the relevant application and to make optimum use of the memory resources
of the DP master.
You configure the system (in other words set a profile) via PROFIBUS using, for
example STEP 7 or COM PROFIBUS. The number of data objects specified by the
selected profile can be assigned to the required instabus EIB components with the
instabus EIB configuration software ETS 2.
Due to the database entry of the DP/EIB link, the instabus EIB configuration
software ETS 2 is capable of displaying the number and data type of the valid
instabus EIB data objects to the user. This allows a simple error-free assignment to
be made. Following configuration, the PROFIBUS-DP master can both write and
read the instabus EIB data objects.
