In addition, TTP devices have accumulated over 1 billion operational hours in SIL4 railway signalling applications.
TTP communication controller chips and IP are available from sources including austriamicrosystems, ON Semiconductor and ALTERA.
With replicated data on both channels, redundant communication is supported[citation needed] As a fault-tolerant time-triggered protocol, TTP provides autonomous fault-tolerant message transport at known times and with minimal jitter by employing a TDMA (Time-Division Multiple Access) strategy on replicated communication channels.
TTP provides a membership service to inform every correct node about the consistency of data transmission.
This mechanism can be viewed as a distributed acknowledgment service that informs the application promptly if an error in the communication system has occurred.
TTP is often used in mission critical data communication applications where deterministic operation is a requirement.
The AS8202NF is required to be loaded with a TASM (TTP Assembler) and MEDL (Message Descriptor List) configuration data sets prior to operation.
The electronic interlocking system “LockTrac 6131 ELEKTRA” was designed within a cooperation of Thales Rail Signalling Solutions division and TTTech[citation needed].
LockTrac 6131 ELEKTRA is an electronic interlocking system that provides the highest levels of safety and availability.
A diagnosis device saves all relevant information to allow efficient maintenance in case of failure[citation needed].
TTP removes the complex interdependencies among modules, simplifying initial application development as well in-service changes and upgrades.
It allows all modules in a system to see all data all of the time, thus ensuring seamless fault accommodation without complex channel change logic[citation needed].
TTP, which is used as a backplane bus, supports high levels of engine safety, operational availability and reduced life cycle cost.
A significant advantage is that all information on the bus is available to both FADEC channels simultaneously[citation needed].
In cooperation with Hamilton Sundstrand Corporation, TTTech developed a TTP-based data communication platform for the electric and environmental control system of the Boeing 787 Dreamliner.
The TTP-designed communication platform prevents an overload in the bus system, even if several important events occur simultaneously.
The two Red Team robotic vehicles competing in the 2005 DARPA Grand Challenge were implemented with "drive-by-wire" technology, in which on-board computers controlled steering, braking and other movements.
