5.5 Constructing a Bus Cable for PROFIBUS DP
The bus cable for connecting PROFIBUS DP devices must be constructed by the
user. A special PROFIBUS cable (twisted pair) is required here. This standard

3079A.
If you plan to construct your own bus cable, the following part numbers are
provided for your convenience.
 PROFIBUS connector: Siemens part number 6ES7972-0BA40-0XA0
 PROFIBUS cable: Belden part number 3079A.
To construct the cable, proceed as follows:
1 Cut the cable to the required length.
2 Prepare the cable ends as shown in the illustration (dimensions in mm):
J PVC Jacket
S Braided shielding
3 Remove the PVC jacket J to the indicated length.
4 Wrap the provided copper shielding F around the shield braiding S:
J PVC jacket
S Braided shielding
F Copper foil shielding
Additional foil can be obtained from 3M.
5 Plug the leads of the corresponding cable(s) into the terminals as shown:
