Commissioning Profibus - Siemens Sinamics S120 Function Manual

Communication
10.2 Communication via PROFIBUS DP
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

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 S120 slave must be available in the
Commissioning steps (example with SIMATIC S7)
1. Set the PROFIBUS address on the slave.
2. Set the telegram type on the slave.
604
The bus terminating resistors in the PROFIBUS plugs must be set as follows:
– First and last nodes in the line: switch in terminating resistor
– Other nodes in the line: switch out terminating resistor
The cable shield must be connected in the plug through a large surface area at both
ends. References: /GH1/ SINAMICS S120 Equipment Manual for Control Units and
