Figure 7.4: FlexRay Interface State Machine State Description FRIF_ST A TE_OFFLINE No communication services are executed (see Chapter 7.6 for details) FRIF_ST A TE_ONLINE All communication services (reception, transmission, transmission confirmation) are executed (see Chapter 7.6 for details). Table 7.1: FlexRay State Machine Transitions (1) [SWS_FrIf_05117] Upstream requirements: SRS_Fr_05031 ⌈During initialization of the FrIf by executing FrIf_Init() the FrIf_State for each cluster shall be initialized with state ’FRIF_ST A TE_OFFLINE’. The transitions are requested by an API service FrIf_SetState() which takes the Cluster to process on and the T ransistion name to invoke. ⌋ [SWS_FrIf_05118] ⌈If the FrIf module’s environment calls the function FrIf_SetState with parameter FrIf_StateT ransition = FRIF_GOTO_ONLINE and if the current state for the requested cluster is FRIF_ST A TE_OFFLINE, the FrIf module shall take the current state of the requested cluster to FRIF_ST A TE_ONLINE.".
