NOTE
The download tool can not execute downloading
during other system connects to the system/
network management VFD of the device.
A6.4 Flow of Software Download
The flowchart below 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 will take about 20 minutes for a
one-to-one connection between a fieldbus device and
download tool, and longer when multiple field devices
are connected to the fieldbus.

Flow of Software Download Procedure
CAUTION
Carrying out a software download leaves the PD
tag, node address, and transducer block calibra-
tion parameters that are retained in the nonvola-
tile 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 down-
load. For details, see Section A6.6.
Select the software file(s) you
want to download.
Select the device(s) to which you
want to download software.
Transmit the software to the field
device(s).
Activate the device(s) to start with
new software.

APPENDIX 6. SOFTWARE DOWNLOAD
CAUTION
The current dissipation of the target field device
increases transitorily immediately after a down-
load due to erasing of the FlashROM's contents.
Use a fieldbus power supply which has sufficient
capacity to cover such increases in feed current.
CAUTION
Upon completion of the activation, the target
fieldbus device performs resetting internally,
which temporarily halts fieldbus 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 field 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 fieldbus link.
If the fieldbus is noisy, the downloading may
take a very long time or fail.
A6.5 Download Files
Download files have the following filenames (with the
filename extension of ".ffd"). Take care to choose the
correct download file for the target field device:
"594543" + device family + "_" + device type + "_"
+ domain name + "_" + software name + "_" +
software revision + ".ffd"
For example, the name of the download file for an EJA
may have the following name:
5945430008_0008_EJA_ORIGINAL_R101.ffd
Refer to A6.11(3) DOMAIN_HEADER about each
keyword of the file name.
