how do i establish Profibus communication between control bulder & siemens drive using GSG file
If you have the correct .GSD file the procedure is relatively simple.
Go to the hw Library and create a new hardware type, create the type and the wizard will request for the hw type file, select your gsd file (look at the extensions) in your PC.
The GSD converter tool will automaticly come up where you may clearly define the mapping of the variables (according to your project needs and siemens manual)
once created you will see that new HW type under the library folder.
in your HW folder, connect the new Library to be used. ad the gsdbrowsing through under a CI854 module (profibus). then you will have your drive with the available fields of control. These you will have to map to your application you have engineered.
Sorry that I am not 100% clear with all the steps, but I am sure you will find yourself easily with help of the wizards.
