# 用語(terms)

|Term|Description|
|:--|:--|
|CanIf |Abbreviation for the CAN Interface
|CanNm| Abbreviation for CAN Network Management
|CBV |Control Bit Vector
|CWU| Car Wakeup
|ERA| External Request Array
|EIRA |External and Internal Request Array
|NM| Network Management
|PNC| Partial Network Cluster
|PNI|Partial Network Information
|PNL| Partial Network Learning
|SNI| Source Node Identifier
|PDU transmission ability is disabled|This means that the Network Management PDU transmission has been disabled by the service CanNm_DisableCommunication.
|Repeat Message Request Bit Indication|CanNm_RxIndication finds the RptMsgRequest set in the Control Bit Vector of a received Network Management PDU.
|PN filter mask |Vector of filter mask bytes defined by configuration container(s) CanNmPnFilterMaskByte
|Top-level PNC coordinator| The top-level PNC coordinator is an ECU that acts as PNC gateway in the network and that handles at least one PNC as actively coordinated on all assigned channels. If synchronized PNC shutdown is enabled, the top-level PNC coordinator triggers for these PNCs the shutdown, if no other ECU in the network request them.
|Intermediate PNC coordinator|An intermediate PNC coordinator is an ECU that acts as PNC gateway in the network and that handles at least one PNC as passively coordinated on at least one assigned channel. If synchronized PNC shutdown is enabled, it forwards received shutdown requests for these PNCs to the corresponding actively coordinated channels and starts their shutdown accordingly.
|PNC leaf node| A PNC leaf node is an ECU that acts not as a PNC coordinator at all in the network. It processes PN shutdown message as usual NM messages.
|PN shutdown message|A top-level PNC coordinator transmit PN shutdown messages to indicate a synchronized PNC shutdown across the PN topology. A PN shutdown message is as NM message which has PNSR bit in the control bit vector and all PNCs which are indicated for a synchronized shutdown set to '1'.
