A11.4 Software Download Sequence; A11.5 Download Files - YOKOGAWA digitalYEWFLO Series User Manual

NOTE
The download tool can not execute downloading
during other system connects to the system/
network management VFD of the device.
A11.4 Software Download
Sequence
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 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.

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 reconfigure the field device(s) after
the download. For details, read APPENDIX 11.6
"Steps after Activating a Field Device."
<APPENDIX 11. SOFTWARE DOWNLOAD (Option /EE)>
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.
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).
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.
Be careful about the noise on the fieldbus link. If
the fieldbus is noisy, the downloading may take a
very long time or fail.

A11.5 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 the
DYF. may have the following name:
5945430009_0009_DYF.-SD_ORIGINAL_R202.
