The integration of a GSD file in HW Config is covered in the SIMATIC documentation.
Suppliers of PROFIBUS components can provide their own bus configuration tool. The
operation of the respective bus configuration tool is described in the relevant documentation.
Note for commissioning for VIK-NAMUR
To be able to operate a SINAMICS drive as a VIK-NAMUR drive, standard telegram 20 must
be set and the VIK-NAMUR identification number activated via p2042 =1.
Identification for individual slaves facilitates diagnostics and provides an overview of the
nodes on the PROFIBUS.
The information for each slave is stored in the following CU-specific parameter:
r0964[0...6] device identification
Bus terminating resistor and shielding
Reliable data transmission via PROFIBUS depends, amongst other things, on the setting of
the bus terminating resistors and the shielding of the PROFIBUS cables.
● Bus terminating resistor
The bus terminating resistors in the PROFIBUS plugs must be set as follows:
– First and last nodes in the line: Switch on terminating resistor
– Other nodes in the line: Switch off terminating resistor
● Shielding of the PROFIBUS cables
The cable shield must be connected in the plug through a large surface area at both ends
(see SINAMICS S120 Control Units and Supplementary System Components Manual).
Commissioning PROFIBUS
Preconditions and assumptions for commissioning
PROFIBUS slave
• The PROFIBUS address to be set for the device application is known.
• The telegram type for each drive object is known by the application.
PROFIBUS master
• The communication properties of the SINAMICS S120 slave must be availa-
ble in the master (GSD file or Drive ES slave OM).
