● Continuously executes the control program.
● Samples a current or voltage signal representing the room temperature and
updates the value associated with that temperature in its memory.
– If the temperature rises to 85°F (29°C), then the TC Compact sends an alarm
message to the printer.
● Checks the current time once per second.
– Between 5:00 P.M. and 7:00 A.M., the fan remains OFF.
– Between 7:00 A.M. and 5:00 P.M., the control program checks the current
value of the temperature and sends the appropriate ON or OFF command to
the fan starter.
If the ON command is issued, the TC Compact updates the value of the starter point in
its memory to reflect the current state of the fan.
System Program
The TC Compact contains a non-volatile system program called firmware , which can
be upgraded in the field. The firmware is stored in Flash ROM memory, which keeps it
virtually immune to all forms of power fluctuations or failure, including battery failure.
For more information on Flash ROM memory, see Memory [➙ 30].
General functionality of the firmware includes:
● Executing control programs.
● Communicating between other field panels and the workstation.
● Monitoring points.
● Managing point-related information.
● Keeping track of real time (both clock and calendar time).
● Executing self-test and error detection in the TC Compact.
License Manager
License Manager adds applications or functionality to a field panel without the need to
replace the hardware or perform a firmware flash. Field panels with Firmware Revision
3.1 or later support the License Management attribute.
Contact your Siemens Solution Partner, Authorized TALON Dealer for more
information on applications and functionality that can be activated through License
Manager.
License Manager Definitions
● A feature is an application or additional functionality that can be added to a field
panel without the need to replace the hardware. Some features require a firmware
flash.
● A
license is the code provided by Siemens Industry to unlock a feature.
● The
ID_STRING is a unique identifier that distinguishes an individual piece of
hardware. It is composed of the panel's part number, revision, year and week of
manufacture, and serial number. Therefore, a license for one field panel will not
work on another field panel.
● An
Entitlement contains the license(s) ordered.
● An
Entitlement ID is the SAP Purchase Order number or Reference number from
the Advanced Shipping notice and your 3 character organization code.
