SNIP_CLASSIC_PLATFORM_SECTION_9_3_Sequence_of_Partial_network_functionality

9.3 Sequence of Partial network functionality The following sequence diagram shows the interaction between Nm and the CanIf module as example. The following deviations has to be considered if using FlexRay communincation stack • FrNm has no ECUC parameter similar to CanNmAllNmMessagesKeepAwake • FrNm needs to check ECUC parameter FrIfImmediate of the NM PDU configured in FrIf • If using FrNm, the NM Pdu is always fechted via FrNm_TriggerTransmit. There is no ECUC parameter similar to CanIfTxPduTriggerTransmit The following deviations have to be considered if using an Ethernet communication stack: • The UdpNm module interacts with the SoAd (and NOT with the EthIf). Therefore UdpNm has to call SoAd_IfTransmit to trigger a transmission of a NM PDU. The SoAd has to call UdpNm_SoAdIfRxIndication to indicate the reception of NM PDU • UpdNm needs to the check the ECUC parameter SoAdBswModules/- SoAdIfTriggerTransmit of the SoAd, to determine if the NM PDU is fetched via call of UdpNm_SoAdIfTriggerTransmit
