5.8 FOUNDATION Fieldbus overview
The configuration of a Rosemount 5400 is normally a simple and straightforward task. If the transmitter
is pre-configured at the factory according to the ordering specifications in the Configuration Data Sheet,
no further Basic Configuration is required unless tank conditions have changed. The Rosemount 5400
supports a set of advanced configuration options as well, which can be used to handle special tank
conditions and applications.
Figure 5-16 illustrates how the signals are channeled through the gauge.

Each FOUNDATION Fieldbus configuration tool or host device has a different way of displaying and
performing configurations. Some will use Device Descriptions (DD) and DD Methods to make
configuration and displaying of data consistent across host platforms. Since there is no requirement that
a configuration tool or host support these features, this section will describe how to reconfigure the
device manually.
This section covers basic operation, software functionality, and basic configuration procedures for the
Rosemount 5400 with F
OUNDATION Fieldbus (Device Revision 3). For detailed information about
F
OUNDATION Fieldbus technology and function blocks used in the Rosemount 5400, see the FOUNDATION
Fieldbus Blocks Reference Manual
.
It is highly recommended that you limit the number of periodic writes to all static or non-volatile
parameters, such as HI_HI_LIM, LOW_CUT, SP, TRACK_IN_D, OUT, IO_OPTS, BIAS, STATUS_OPTS,
SP_HI_LIM, and so on. Static parameter writes increment the static revision counter, ST_REV, and are
written to the device's non-volatile memory. Fieldbus devices have a non-volatile memory write limit. If
a static or non-volatile parameter is configured to be written periodically, the device can stop its normal
operation after it reaches its limit or fail to accept new values.
