Communication (5.)
Note
Default settings in the parameter tables are indicated with an asterisk (*) unless explicitly
stated.
Tag (5.1.)
Note
The tag can only be changed from a remote master such as NIFBUS
-Configurator or DeltaV.
Read only. Text that can be used in any way. A recommended use is as a unique label for a field
device in a plant. Limited to 32 ASCII characters.

Note
The address can only be changed from a remote master such as NIFBUS
-Configurator or
DeltaV. See Addressing
in manual
Foundation Fieldbus for Level Instruments
(7ML19985MP01) for further details.
Read only. The unique address of the device on the network.
Values
Temporary range during initial commissioning: 248 - 251. Permanent range
after commissioning complete (written to non-volatile memory in the device):
16-247
