Siemens SINAMICS S120 Function Manual page 733

The SINAMICS S DXB GSD file contains among other things standard telegrams, free
telegrams and slave-to-slave telegrams for configuring slave-to-slave communication. With
the aid of these telegram parts and an axis separator, a telegram for the drive unit must be
composed for each drive object.
Processing a GSD file in HW Config is covered in the SIMATIC documentation. Suppliers of
PROFIBUS components can provide their own bus configuration tool. The description 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.
Device identification
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
● Shielding of the PROFIBUS cables

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
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).
