TTP/A

TTP/A is a time-triggered real-time fieldbus protocol used for the interconnection of low-cost smart transducer nodes. In contrast to the Time-Triggered Protocol (TTP), which is a high-speed, fault-tolerant communication network intended for safety critical applications ( SAE class C), TTP/A provides a low-speed (below 1 MB/s), low-cost protocol suitable for non-critical applications like car body electronics (SAE class A).
