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.
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 6- 29
PROFIBUS address switches
Rotary coding switches
The factory setting for the rotary coding switches is 0
Setting the PROFIBUS ID number
The PROFIBUS Ident Number (PNO-ID) can be set using p2042.
SINAMICS can be operated on PROFIBUS with various identities. This allows a PROFIBUS
GSD that is independent of the device to be used (e.g. PROFIdrive VIK-NAMUR with Ident
Number 3AA0 hex).
● 0: SINAMICS S/G
● 1: VIK-NAMUR
New settings do not become active until after POWER ON, reset, or download.
