6.4.2 Communication Settings PROFBUS DP
Setting the PROFIBUS DP address
Prior to using the PROFIBUS DP interface, the address of the node (inverter) must be set.
There are two methods for setting the PROFIBUS DP address:
● Using the seven DIP-switches on the Control Unit
● Using parameter "P0918"
CAUTION
If changing the PROFIBUS DP address, a power cycle is necessary for the Control Unit
CU240S to make the new PROFIBUS DP address setting effective. The restart must be
initiated by switching the power off and then on again, irrespective of whether the
interface is supplied from the inverter mains supply or its own, separate 24 V power
supply connection.
