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 the 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.
Note
Only values from 1 to 126 (7E
set, then the set value is interpreted as "0". If a value "0" or "127" is set, the value in parameter
p0918 defines the PROFIBUS address.
PROFIBUS interface in operation
Generic station description file
A generic station description file clearly and completely defines the properties of a PROFIBUS
slave.
The SINAMICS S GSD file contains among other things standard telegrams, free telegrams
and slave-to-slave telegrams for configuring slave-to-slave communication. With the aid of
these telegram parts and an axis separator, a telegram for the drive unit must be composed
for each drive object.
The GSD files can be found:
