Displaying the Unique Identifier
This function enables reading of the Unique Identifier (unique
HART address), which has to be known for almost all the
HART addressing commands. However this information is only
required for those systems that are not able to read back the
Unique Identifier using HART command #0 in Short-Frame
Format or HART command #11. The display corresponds to
the address for HART command #0 (Read Unique Identi
fi
er) or
#11 (Read Unique Identi
fi
er associated with Tag).

Select
Settings > Communication > HART interface >
Unique Identifier
and confirm.
The Unique Identifier is displayed.
Changing the tag name
The tag can be used to identify special devices. It can contain
up to 8 alphanumeric characters. The tag can also function as
an address for reading the unique identifier from the device
using HART command #11 (Read Unique Identifier Associated
With Tag), even when the polling address is unknown.
This requires that a unique tag has previously been configured.
