Basic Configuration/Start-up
5.9 FOUNDATION fieldbus overview
The configuration of a Rosemount 5400 Series transmitter is normally a simple and straightfor-
ward 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 Series supports a set of advanced
configuration options as well, which can be used to handle special tank conditions and
applications.
Figure 5-15 illustrates how the signals are channeled through the gauge.

Transmitters with F
OUNDATION fieldbus
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 Series Level Transmitter with F
OUNDATION fieldbus (Device Revision 3).
For detailed information about F
OUNDATION fieldbus technology and function blocks used in the
Rosemount 5400 Series, refer to the F
OUNDATION fieldbus Blocks Manual
(Document No. 00809-0100-4783).
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.
