PROFIBUS address switches
The PROFIBUS address is set as a hexadecimal value via two rotary coding switches.
Values between 0
dec
(00
hex
) and 127
dec
(7F
hex
) can be set as the address. The upper rotary
coding switch (H) is used to set the hexadecimal value for 16
1
and the lower rotary coding
switch (L) is used to set the hexadecimal value for 16
0
.

Setting the PROFIBUS address
The factory setting for the rotary coding switches is 0
dec
(00
hex
).
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
code switches to 0
dec
(00
hex
) and 127
dec
(7F
hex
).
– 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
switches. In this case, p0918 is only used to read the address.
Note
The rotary coding switches used to set the PROFIBUS address are located beneath the
cover.
