– If the field panel resides on an ALN with a TALON View workstation, the
TALON View workstation sets the time-date when the field panel returns to the
network.
– If the field panel resides on an ALN without a TALON View workstation, the
time-date is synchronized with the network time during the next automatic daily
time update.
For more information on time synchronization, see the TALON Firmware User's
Manual (588-580) (588-580).

Memory
The TALON firmware (program), its point database, PPCL program, trend data, and
other information reside in the field panel memory. Memory consists of two areas:
Flash Read-Only Memory (Flash ROM) and Random Access Memory (RAM).
Flash Read-Only Memory (Flash ROM)
Flash Read-Only Memory (Flash ROM) is the non-volatile, permanent memory of the
TC Modular, which stores the operating system, the TALON firmware, and the
language files. A limited amount of secondary storage is provided in Electrically
Erasable Programmable Read-Only Memory (EEPROM) for the field panel address or
name, communication speeds, and other set-up parameters. In the event of a power
surge, a power loss, or failure of the battery backup, the Flash ROM and EEPROM
contents stay intact.
TC Modular Flash ROM size cannot be upgraded in the field.
Compressed ROM
The TC Modular has a large amount of high performance RAM. To allow for future
features and to provide high system performance, the TALON firmware is stored in
ROM in a compressed state; it is de-compressed into RAM on system power-up. As a
result, the entire onboard RAM is not available for the point database, the PPCL
program, and trend data.
Auto-Restore and Database Backup to Flash
TALON Firmware Revision 3.1 and later supports Auto-Restore and Database Backup
to Flash.
● Database Backup to Flash allows the user to manually save a copy of the
database in flash memory of the controller.
● The field panel may be configured to automatically restore the database from flash
memory after a coldstart.
