SNIP_CLASSIC_LINIF_SECTION_7_6_2_1_Node_Model

7.6.2.1 Node Model The LIN Interface uses the Node Model defined in the ISO 17987-3 specification that describes where the configuration is stored for slave nodes. The LIN Interface manages the currently configured NAD and PIDs of the slave node. The slave node shall have a valid configuration after reset in order to be addressed by node configuration services and to be able to process Relevant frames. [SWS_LinIf_00767] ⌈The LIN Interface shall initialize the initial NAD and configured NAD of the slave node from the configuration data (configuration parameters LinIfInitialNAD and LinIfConfiguredNAD) in function LinIf_Init.⌋ Note: The initial NAD is statically configured, i.e. does not change during runtime and is used for “Assign NAD” requests. The configured NAD might change after initialization, either by an “Assign NAD” request or by upper layer, and is used for node configuration services (other than “Assign NAD”) and transport protocol. [SWS_LinIf_00768] ⌈The LIN Interface shall initialize the configured PIDs of the slave node from the configuration data (configuration parameters LinIfFrameId) in function LinIf_Init.⌋ Note: The current configuration of the node can be updated by upper layer using LinIf_SetConfiguredNAD and LinIf_SetPIDTable (e.g. with data loaded from non-volatile memory) or by the LIN master node using node configuration commands. [SWS_LinIf_00769] ⌈The LIN Interface shall provide the LIN product identification (as described in the ISO 17987-3 specification) consisting of supplier ID, function ID and variant ID (configuration parameters LinIfSupplierId, LinIfFunctionId and LinIfVariantId).⌋
