Software Download Sequence
Figure 83 outlines the software download procedure.
Although the time taken for the entire procedure varies depending on the size of the
field bus device's software, it generally take about 20 minutes where there is a
one-to-one connection between a fieldbus device and download tool, and longer when
multiple field devices are connected to the fieldbus.

address, and transducer block calibration parameters that
are retained in the nonvolatile memory inside the target
device, but may reset other parameters to the defaults
(except a minor update that does not change the number of
parameters).
Hence, where necessary, save the parameters using an
engineering tool, parameter setting utility, or the like before
carrying out a software download, and then reconfigure the
field device(s) after the download. For details, see "Steps
after Activating a Field Device" on page 243.
The current dissipation of the target field device increases

transitorily immediately after a download due to erasing of
the FlashROM's contents. Use a fieldbus power supply
which has sufficient capacity to cover such increases in feed
current.
