Note
The factory settings are "ON" or "OFF" for all switches. With these two settings, the
PROFIBUS address is set by parameterization.
Parameter p0918 is unique to the Control Unit (see Control Unit). The factory setting is 126.
Address 126 is used for commissioning. Permitted PROFIBUS addresses are 1 ... 126.
If more than one CU is connected to a PROFIBUS line, the address settings must differ from
the factory settings. Note that each address can only be assigned once on a PROFIBUS
line. This can be achieved using the address switch or by adjustable parameter p0918
accordingly. The setting can be made by connecting the 24 V supply step by step and
resetting p0918, for example.
The address setting on the switch is displayed in r2057.
Each change made to the bus address is not effective until POWER ON.
