Time-Triggered Protocol

The Time-Triggered Protocol (TTP) was specifically designed to meet all requirements in connection with the implementation of fault-tolerant systems. TTP has its special focus on safety-critical high-speed applications. That results in low costs and a high protocol efficiency.

TTP is based on more than 25 years of development work. During that time a great number of patents were filed and the protocol was stabilized. All those activities resulted in the bringing of the first TTP communication controller onto the market in 1998.

TTP involves a continuous communication of all connected nodes via redundant data buses at predefined intervals of microseconds. The design ensures that an overload in the bus system is prevented even if several important events occur simultaneously. All events are safely processed according to schedule without data collision.
