Start with your hardware config. Add the drive to Profibus and set the addresses. With the addresses set the manual should show you what does what.
 
I would read the SSD Drives Profibus Tech box manual it runs through the connection in Simatic Manager and shows how to configure the drive.

SSD Profibus Tech Box Manual is here

The GSD Files are here

The GSD File editor is here (You may not need this)

Config ED Lite for easy configuration of the SSD Drive is here (to use this you will need the appropriate cable from SSD, you can configure from the keypad but that is harder if changing links etc!)

I have been using SSD for 20 years now so if you have any config trouble with Configed lite (It takes a bit of getting used to) ill try to help out.

edit: You may need to create a log in at ssd to access the manuals and files etc

edit2: Forgot the pdf for the GSD Editor here

edit3: If you just want to set the comms up for profibus thats quite easy on the keypad. If you want to alter links in the drives config like say programming the blocks in the drive to stop the drive if profibus looses comms then that is harder from the keypad which is why i suggest config ed lite.
