SNIP_CLASSIC_STD_SECTION_9_5_Synchronized_PNC_shutdown

9.5 Synchronized PNC shutdown Note: The sequence diagrams shows the expected behaviour, but not the implementation Figure 9.5 shows the request for a synchronized PNC shutdown if an ECU in the role of a top-level PNC coordinator detects a release of a PNC. «module» ComM «module» Nm «module» <Bus>Nm Network Mode Normal Operation COMM_PNC_REQUESTED COMM_PNC_READY_SLEEP <Bus>If opt Create a NM-PDU [Transmission of PN shutdown message has been activated] [Transmission of PN shutdown message has been de-activated and request to transmit a cycle NM-PDU is available] alt Transmit NM-PDU either as PN shutdown message or as typical cyclic NM message alt Requests for synchronized PNC shutdown pending opt NM-PDU is configured for immediate transmission
