A8.4 Software Download
Sequence
The owchart below outlines the software download
procedure. Although the time taken for the entire
procedure varies depending on the size of the eld
bus device’s software, it generally take about 20
minutes where there is a one-to-one connection
between a eldbus device and download tool, and
longer when multiple eld devices are connected to
the eldbus.

Figure A8.2 Flow of Software Download Procedure
CAUTION
Carrying out a software download leaves the
PD tag, node 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 recongure the eld device(s) after the
download. For details, see Section A8.6.
CAUTION
The current dissipation of the target eld
device increases transitorily immediately after
a download due to erasing of the FlashROM’s
contents. Use a eldbus power supply which
has sufcient capacity to cover such increases in
feed current.
CAUTION
Upon completion of the activation, the target
eldbus device performs resetting internally,
which temporarily halts eldbus communication
and function block executions. Be especially
careful about a valve positioner; the output air
pressure will fall to the minimum level (i.e., zero).
CAUTION
Do not turn off the power to a eld device or
disconnect the download tool during a download
or activation. The device may fail as a result.
NOTE
Be careful about the noise on the eldbus link. If
the eldbus is noisy, the downloading may take a
very long time or fail.
A8.5 Download Files
Download les have the following lenames (with
the lename extension of “.ffd”). Take care to
choose the correct download le for the target eld
device:
“594543” + device family + “_” + device type +
“_” + domain name + “_” + software name + “_”
+ software revision + “.ffd”
For example, the name of the download le for an
FVX110 may have the following name:
5945430010_0010_FVX110_ORIGINAL_
R101.ffd
Refer to A8.10(3) DOMAIN_HEADER about each
keyword of the le name.
The device type is “0010” for an FVX110.
The software name is “ORIGINAL” or “UPDATE.”
The former indicates an original le and the latter
an update le. Whenever performing a download
to update the device revision, obtain the original le.
In general, an addition to the parameters or blocks
requires a device revision update.
