Siemens 125-3584T manual Performance and Limitations

Chapter 2 - Field Panel Web Server System Administration

Performance and Limitations

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.
