Select fieldbus address
A fieldbus address is usually automatically assigned to the connected field devices by the CFU
PA.
Note
Fieldbus addresses 2 and 3
Fieldbus addresses 2 and 3 are used internally.
● If you connect field devices with these addresses to the CFU PA, automatic addressing of
the field devices will not be possible.
● To prevent malfunctions of the CFU PA, avoid connecting field devices with these
addresses to the CFU PA.
Note
Field devices with hardware-coded address
For field devices with hardware-coded address setting, automatic assignment of a fieldbus
address is not possible.
Set the fieldbus devices such that the field device receives the address via the software.
If this is not possible, set the fieldbus address of the field device to the address suitable for the
fieldbus connection before connecting it to the CFU PA. You can find information on the fieldbus
addresses of the CFU PA in section "PROFIBUS addresses of the PROFIBUS PA field devices
on the CFU PA (FBn) (Page 189)".
