PROFIBUS address switches
The PROFIBUS address is set as a hexadecimal value via two rotary coding switches.
Values between 0
coding switch (H) is used to set the hexadecimal value for 16
switch (L) is used to set the hexadecimal value for 16
Table 4- 15
Setting the PROFIBUS address
The factory setting for the rotary coding switches is 0
There are two ways to set the PROFIBUS address:
1. Via p0918
– To set the bus address for a PROFIBUS node using STARTER, first set the rotary
– Then use parameter p0918 to set the address to a value between 1 and 126.
2. Via the PROFIBUS address switches on the Control Unit
– The address is set manually to values between 1 and 126 using the rotary coding
