A7.6 Steps after Activating a
Field Device
When the communication with a eld device has
recovered after activating the device, check using
the download tool that the software revision of the
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, see the table below.
Also note that a change in the number of
parameters or blocks requires the DD and
capabilities les corresponding to the new software
revision.

A7.7 Troubleshooting
For information on the download tool’s error messages, see also the software’s User’s Manual.
Table A7.2 Problems after Software Update
Symptom Cause Remedy
An error occurs before starting a
download, disabling the download.
The selected download le is not for
the selected eld device.
Check SOFTDWN_ERROR in the
resource block and obtain the correct le.
An error occurs after starting a
download, disabling the download.
You attempted to update the device
revision by downloading a le which is
not an original le.
Check SOFTDWN_ERROR in the
resource block and obtain the original le.
The selected eld device does not
support software downloading.
Check whether the option code /EE is
included in the model and sufx codes of
the device.
The voltage on the eldbus segment
falls below the specied limit (9 volts).
Check the capacity of the eld bus power
supply used and the voltage at the terminal.
There was an error in a checksum or
the number of transmission bytes.
Check SOFTDWN_ERROR in the
resource block and obtain the correct le.
The download tool does not allow
download with same software revision.
Check the setting of the download tool.
The download takes far longer than
expected or fails frequently.
The eldbus segment is noisy. Check the noise level on the eldbus
segment.
An error occurs after activation. Transient error caused by the internal
resetting of the eld device.
Check whether communication with the
eld device has recovered after a while.
The new software does not work
after the activation.
The le of the current revision was
downloaded.
Obtain the correct le.
Failure of the memory in eld device,
etc.
Check SOFTDWN_ERROR in the
resource block, and re-try downloading.
If fails, place a service call.
