Webcycle, it is assigned a static slot in the FlexRay communication schedule. However, it is also possible to assign multiple nodes to a slot, when their frames do not have to be sent every Webutilization of the FlexRay bus. An example of this cycle multiplexing for a single slot is illustrated in Figure 3. The cycle multiplexing of messages is defined by the base cycle and the cycle repetition: The base cycle defines the offset in cycles for the first occurrence of the respective message. The cycle repetition denotes the frequency
WebJun 1, 2015 · The FlexRay Media Access Control (MAC) protocol is based on a fixed time-division cycle, the FlexRay cycle (FC), that periodically repeats itself. Each cycle is composed of a Static Segment (ST), a Dynamic Segment (DN) and two control segments, the Network Idle Time (NIT) and the Symbolic Window (SW).
