Folders access rights

Each folder has specific access rights, depending on function.
The access rights can be:
• Listing: it is only possible to list the files in the folder, but
no read or write operation is possible
• Read-only: it is possible to read files from the folder but
uploading files to the device is unauthorized.
• Read-write: it is possible to perform both reading and
writing operations to the folder
• Write-only: location meant to be used only to add or
substitute files
Access rights for each folder are listed In the following table:
Folder path Access rights Notes
Upgrade Write-only
Security\key Listing
Security\certs Read-only
LOG Read-only
Data Read-only
Config Read-write
Table 2 Access rights
Note . If the Media Card is not fitted and online, only Security
folders are visible.

Software Upgrades

FTP communications allow the operator to transfer new
software updates via the Ethernet connection, making the
operation of unplugging the Media Card from the instrument
and plugging it into a laptop unnecessary and thus easing the
task of service engineers, speeding up operations and reducing
instrument downtime.
However, it is still necessary to follow the upgrade instructions
for both transmitter and sensor modules. Refer to ABB Library
and the upgrade instructions for details. Please note this
procedure applies for upgrades of both transmitter and sensor
software.
Because web browsers do not support uploading operations to
a remote FTP server, to transfer the software upgrade files it is
necessary to use an FTP client. In this example FileZilla is used
for reference (other FTP clients may have slightly different
operating procedures).
To upload a new transmitter software version to the
instrument, unzip the zip file containing the software upgrade
downloaded from the ABB library. Then connect to the
instrument as explained in the previous section. Navigate to
the folder containing the new software on the local hard drive
inside FileZilla (left-hand side in the picture below).
Software upgrades. Refer to Software
Upgrades (below) for details
Secure folder
Contains digital certificates that can be read
Contains log files that can be analyzed
externally
Contains data recorded by the device that
can be retrieved and analyzed externally
Contains configuration data that can be
uploaded to the device to change its mode
of operation
On the right-hand side of the FileZilla window, navigate the
folder structure on the instrument.
Figure 27 FileZilla connected to the AWT420
Copy the folder on the left (local drive) to the right
(instrument's storage). Either drag-and-drop or right-click on
the folder to be uploaded and select Upload. The end result will
be similar to the example below:
Figure 28 FileZilla FTP transfer successful
Selecting the Successful transfers tab at the bottom of the
application shows that the upload has completed successfully.
Now it is possible to disconnect from the remote instrument as
the upload is complete and the device software can be
upgraded. For this procedure, please refer to the upgrade
instructions mentioned above.
