APPENDIX 6. SOFTWARE DOWNLOAD
The device type is “000B” for the AXF .
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 nonvola-
tile 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 corre-
sponding to the new software revision.
