Assigning device tag and node address

A Rosemount 5400 Series transmitter is shipped with a blank tag and a temporary address
(unless specifically ordered with both) to allow a host to automatically assign an address and a
tag. If the tag or address need to be changed, use the features of the configuration tool. The tool
basically does the following:
1.
2.
3.
When the transmitter is at a temporary address, only the tag and address can be changed or
written to. The resource, transducer, and function blocks are all disabled.

OUNDATION
Function blocks within the fieldbus device perform the various functions required for process
control. Function blocks perform process control functions, such as Analog Input (AI) functions,
as well as Proportional/Integral/Derivative (PID) functions. The standard function blocks provide
a common structure for defining function block inputs, outputs, control parameters, events,
alarms, and modes, and combining them into a process that can be implemented within a single
device or over the fieldbus network. This simplifies the identification of characteristics that are
common to function blocks.
In addition to function blocks, fieldbus devices contain two other block types to support the
function blocks. These are the Resource block and the Transducer block.
Resource blocks contain the hardware-specific characteristics associated with a device; they
have no input or output parameters. The algorithm within a resource block monitors and
controls the general operation of the physical device hardware. There is only one resource block
defined for a device.
Transducer blocks connect function blocks to local input/output functions. They read sensor
hardware and write to effector (actuator) hardware.
Level transducer block
The Level Transducer block contains transmitter information including diagnostics and the
ability to configure, set to factory defaults and restarting the transmitter.
Register transducer block
The Register Transducer block allows a service engineer to access all database registers in the
device.
Advanced configuration transducer block
The advanced configuration transducer block contains functions such as amplitude threshold
settings for filtering of disturbing echoes and noise, simulation of measurement values and
strapping table for volume measurements.
