2.4 Setting the PROFIBUS DP address

Before the PROFIBUS DP interface is used, the address of the node point

(inverter) must be set.

The following methods are available for setting the PROFIBUS DP address:

• Using the address switch on the Control Unit

• Using parameter p0918

Note

Important notes for setting the PROFIBUS address

The address setting on the DIP switch takes priority over the p0918

settings.

The PROFIBUS DP address can only be set using p0918 when the

address 0 is set on the DIP switches of the Control Unit (factory setting).

When the address switch is set to a value ≠ 0, the setting in p0918 is

ignored.

The valid address range for Siemens controllers is 1 to 125. Addresses 126

and 127 cannot be used with SIMATIC controllers.
