Communication
10.2 Communication via PROFIBUS DP
● PROFIBUS interface
● PROFIBUS diagnostic LED
Note
A teleservice adapter can be connected to the PROFIBUS interface (X126) for remote
diagnostics purposes.
On the CU320-2, the PROFIBUS address is set as a hexadecimal value using 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 10- 58 PROFIBUS address 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 parameter p0918
2. Using the PROFIBUS address switches on the Control Unit
728
The PROFIBUS is described in the "SINAMICS S120 Control Units and Supplementary
System Components Manual".

– To set the bus address for a PROFIBUS node using STARTER, first set the rotary
code switches to 0
dec
– Then use parameter p0918 to set the address to a value between 1 and 126.
– The address is set manually to values between 1 and 126 using the rotary coding
switches. In this case, p0918 is only used to read the address.
