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.
Note
Address 126 is used for commissioning. Permitted PROFIBUS addresses are 1
... 126.
When several Control Units are connected to a PROFIBUS line, you set th
e addresses
differently than for the factory setting. Each PROFIBUS address in a PROFIBUS line can
only be assigned once. Either set the PROFIBUS address in absolute terms using the rotary
coding switches
– or selectively in parameter p0918. Each change made to the bus address
is not effective until POWER ON.
The currently set address of the rotary coding switch is displayed in parameter r2057.
