Use the HMI “Uiupgrade” function
(System/Hardware/Ethernet/Webserver/Uiupgrade)
Use FTP to transfer the uiupgrade.txt file from Vantage Web site or your computer
to the root of Drive A on the field panel.
After the upgrade is complete, the UIupgrade folder is automatically removed from
Drive A. No coldstart is necessary.
If a coldstart occurs, all files are preserved in the IFD.
Performance and Limitations An interface is available via the Human-Machine Interface (HMI) to save files to
and restore files from the RAM drive, USB media, or the Field Panel’s internal flash
drive (IFD). For more information, see the TALON Controllers User's Manual (588-
580).
Graphics files can be published from the Siemens FINlite Graphics Tool to the field
panel’s RAM (Drive A) or USB (Drive B). For graphics to be preserved across a
coldstart, files must be saved on the internal flash drive (IFD) or stored on a USB
drive. Any graphics files stored only on the panel’s RAM drive will not be preserved
across a coldstart. Files can be saved to the IFD using the Graphics Backup
feature in the HMI.
There are 8MB of RAM available on the RAM (Drive A), but it is recommended that
4MB of RAM is kept available for field panel operations. Individual graphic sizes
typically range from 300KB to 500KB, depending on background resolution.
Cache refresh time is affected by the number of objects and FLN devices on the
panel. Panels with multiple FLN applications will experience longer refresh times.
USB devices must be formatted as FAT. Due to USB memory device
manufacturer, size, and contents, the time to detect the device will vary from
several seconds to one or more minutes.
The following devices are supported by the installed device drivers. Cruzer,
SanDisk, and Kingston brand devices were used during development and testing.
