7.4 Loading New Web Server Content
The interface card’s web server resides in the file system and can be updated in the field (refer to
section 6.4). This section will discuss how to update the default web server. The update procedure
similarly applies to a custom web server. Web server updates may be released for a variety of reasons,
such as improvements and added functionality. When using the default web server, it is always
recommended to use the latest release.
Treat web server updates independently of firmware updates since web server updates may or may not
be related to firmware updates. The latest default web server can be downloaded from the product
web
page. It is suggested that users first check this website during commissioning, and then periodically
afterwards to determine if a new default web server has been released and is available to update their
units.
Besides the new “WEB” folder containing the new web server, the update requires a USB or FTP
connection as described earlier in this section. To update the web server, complete the following steps:
1. Navigate to the card’s file system (see section 7.2 or section 7.3).
2. Backup the “WEB” folder if desired by copying it to the local computer.
3. Delete the “WEB” folder from the card’s file system.
4. Copy the new “WEB” folder to the card’s file system.
5. Power-cycle or reset the card.
6. Clear your internet browser’s cache to ensure that the new web server content will be properly
loaded from the interface card.
