A
ny new Web Server panel must be made ready before Auto Save will work. Fifteen
minutes after the panel is made ready, the database will be automatically saved.
Manually or automatically saving the database can cause the device to fail
momentarily.
It is recommended that you leave the Auto Save feature enabled to ensure that the
Web Server User Interface, Graphics, and Field Panel database are backed up. For
more information about Auto Save, see the TALON Controllers User's Manual (588-
580).
Available Memory Diagnostic Point
The Field Panel Web Server provides a diagnostic point called

MEMAVAIL

, which
displays the available memory in the controller.
The MEMAVAIL point is a trendable, virtual point which resides in the analog values
option of the local controller.
Although it is a virtual point, the MEMAVAIL point

cannot

be commanded. If the point is
commanded, a success message displays in the Commander window, but the point
value reverts back to the actual available memory in the controller, rather than the
commanded value.
