Assigning device tag and node address

A Rosemount 5400 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. Changes the address to a temporary address (248-251).
2. Changes the tag to a new value.
3. Changes the address to a new address.
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 Propor-
tional/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.
Resource block
There are no linkable inputs or outputs to the Resource block.
