5.14 Software Upgrade
Whenever you connect to the WebAlert via an Internet connection, it will check to see if any software
upgrades are available. If there are, then the Software Upgrade page link will appear. Note that this can
only occur if the WebAlert is connected to the Internet, either through the modem or Ethernet.
If there is a newer version of software that you would like to load into your unit, then you can upgrade
to the latest revision.
Click on the link “More Info on Software Upgrade” to see what features have been added.
Click on the link “Start Software Upgrade” in order to download the new version to the unit.
Note: Process monitoring is suspended during a software upgrade. If the unit being updated is a slave
on a network of controllers, both the master unit and the slave being updated will have process
monitoring suspended during the upgrade process. Depending upon the extent of the changes and
Internet traffic, the upgrade can take anywhere from 15 minutes to 2 hours to complete.
If the WebAlert is not connected to the Internet, an upgrade may be accomplished using an upgrade file
and USB flash drive:
Download the upgrade file from the Walchem web site. Certain upgrade files will only work to go from
a few specific versions to another. Make sure that the upgrade file matches the software version you
have now. The current WebAlert software version is displayed on the System Summary page.
Save the file to an USB flash drive. It must be the only executable file on the root directory of the flash
drive.
Insert the USB flash drive into the USB host connector (see figure 5).
Connect to the WebAlert via USB or Ethernet and after the IP address type the command
/cmd_lupsw.txt.
Click on the link for Software Upgrade, then the link to Start Software Upgrade.
The software upgrade will begin. When it is complete, after a few minutes, the WebAlert will reboot.
Reconnect via USB or Ethernet and check the software version number of the System Summary page to
verify that the upgrade is complete.
5.15 Configuration File
If many of your process monitoring applications are nearly identical, you can save a lot of time in the
set up by downloading a typical configuration file to your hard drive, and later uploading the
configuration file to another process monitor.
Export UCF
In order to transfer the User Configuration File (UCF) from the WebAlert to your computer, click the
Export UCF link. You will be presented with the standard Windows dialog box to download a file.
Click the radio button to Save this file to Disk, then click OK. Select the location where you want the
file to be saved, change the name of the file if desired, then click Save. The file is only around 14KB, so
it should be transferred relatively quickly. Click Close to close the dialog box.
The exact sequence of events and wording within the dialog box will vary depending upon the
operating system (Windows 95, 98, NT, 2000, XP etc.) on your PC.
