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.
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 a AV550G may have the following name:
5945430401_0401_AV550G_ORIGINAL_R101.ffd
Refer to A1.11(3) DOMAIN_HEADER about each keyword of the file name.
The device type is “0401” for a AV550G (with software download capability).
The software name is “ORIGINAL” or “UPDATE.”
The former indicates an original file and the latter an update file. Whenever performing a download to
update the device revision, obtain the original file. In general, an addition to the parameters or blocks
requires a device revision update.
A6.6 Steps after Activating a Field Device
When the communication with a field device has recovered after activating the device, check using
the download tool that the software revision of the field device has been updated accordingly. The
value of SOFT_REV of the resource block indicates the software revision.
The PD tag, node address, and transducer block calibration parameters that are retained in the
nonvolatile memory inside the target device will remain unchanged after a software download.
However, after a software update which causes an addition to the block parameters or blocks, or to
the system/network management VFD parameters, some parameters may be reset to the defaults,
thus requiring parameter setup and engineering again. For details, see the table below.
Also note that a change in the number of parameters or blocks requires the DD and capabilities files
corresponding to the new software revision.
