Device identification
An identification parameter 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 for
the bus terminating resistors and the shielding for 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 for the PROFIBUS cables
The cable shield in the plug must be connected at both ends with the greatest possible
surface area.

9.3.2.2 Commissioning procedure
Preconditions and assumptions for commissioning
PROFIBUS slave
● The PROFIBUS address to be set for the application is known.
● The telegram type for each drive object is known by the application.
PROFIBUS master
● The communication properties of the SINAMICS S110 slave must be available in the
master (GSD file or Drive ES slave OM).
Commissioning steps (example with SIMATIC S7)
1. Set the PROFIBUS address on the slave.
2. Set the telegram type on the slave.
