References: /GH1/ SINAMICS S120 Equipment Manual for Control Units and Additional
System Components
– In this case, p0918 is read-only and simply displays the set address.
– A change is not effective until POWER ON.
– You can only use this method when all the PROFIBUS address switches from S1 to
S7 are set to ON or OFF.
– Address changes made via parameters must be saved in a non-volatile memory using
the "Copy from RAM to ROM" function.
– A change is not effective until POWER ON.
