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
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 also Chapter "PROFIBUS connection (Page 455)".
10.4.3.3
Commissioning PROFIBUS
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 DCM slave must be available in the
master (GSD file or Drive ES slave OM).
