PROFIBUS address switch

The PROFIBUS address for the CU310-2 DP is set as a hexadecimal value on two rotary
coding switches.
Values may be set 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

Setting the PROFIBUS address
The factory setting for the rotary coding switches is 0
The PROFIBUS address is set as follows:
1. via a parameter (see SINAMICS S120/S150 List Manual)
– To set the bus address for a PROFIBUS node using STARTER, first set the rotary
– Then use the parameter to set the address to a value between 1 and 126.
2. via PROFIBUS address switch
– The PROFIBUS address is set manually to a value between 1 and 126 on the two
