16.4 System Functions
16.4.1 SFC 75 - SET_ADDR - Set PROFIBUS MAC address
With this SFC you can change the MAC address of the integrated PROFIBUS interface of
a CPU. The function is only possible in the passive DP slave mode. To identify the diag-
nostic address is used. The SFC is asynchronous and can be applied only to one inter-
face. At STOP and subsequent warm start the set network address is retained. With Pow-
erOFF-PowerON or on overall reset the interface gets the configured node number The
DP slave consistently assumes the identity of the DP slave with the new address. For the
DP master the DP slave with the old address fails and a DP slave with the new address
returns. If an address is selected, which is already used by another node on the DP line,
then both slaves fail in accordance to the DP communication.
