The device type is “0009” for the digitalYEWFLO.
The software name is “ORIGINAL” or “UPDATE.”
The former indicates an original fi le and the latter
an update fi le. Whenever performing a download to
update the device revision, obtain the original fi le.
In general, an addition to the parameters or blocks
requires a device revision update.
A11.6 Steps after Activating a
Field Device
When the communication with a fi eld device has
recovered after activating the device, check using
the download tool that the software revision of the
fi eld 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, refer to Table A11.1.
Also note that a change in the number of
parameters or blocks requires the DD and
capabilities fi les corresponding to the new software
revision.
