● PROFIBUS interface
The PROFIBUS is described in the "SINAMICS S120 Control Units and Supplementary
System Components Manual".
● PROFIBUS diagnostic LED
Note
A teleservice adapter can be connected to the PROFIBUS interface (X126) for remote
diagnostics purposes.
On the CU320-2 DP, the PROFIBUS address is set as a hexadecimal value via two rotary
coding switches. Values between 0
The upper rotary coding switch (H) is used to set the hexadecimal value for 16
lower rotary coding switch (L) is used to set the hexadecimal value for 16
Table 11- 7
Rotary coding switch-
Setting the PROFIBUS address
The factory setting for the rotary coding switches is 0
There are two ways to set the PROFIBUS address:
1. Using a parameter
– To set the bus address for a PROFIBUS node using STARTER, first set the rotary
– Use the parameter to set the address to a value between 1 and 126.
Information can be taken from the following reference:
Reference: SINAMICS S120/S150 List Manual
2. Using the PROFIBUS address switches on the Control Unit
– The address is set manually to values between 1 and 126 using the rotary coding
