SNIP_CLASSIC_LINIF_SECTION_7_6_2_4_Node_Configuration_Handler

7.6.2.4 Node Configuration Handler The Node configuration handler implements the functionality to evaluate, process and respond to node configuration requests supported by the LIN Interface. A “valid node configuration request” is a MRF with NAD addressing the slave node (initial or broadcast/wildcard NAD for “Assign NAD” request, configured or broadcast/ wildcard NAD for the other supported services), PCI as defined in the ISO 17987-3 specification and a SID value of a supported node configuration service. [SWS_LinIf_00778] ⌈The LIN Interface shall support wildcards for Function Id, Supplier Id and NAD in node configuration requests (as defined in the ISO 17987-3 specification).⌋ [SWS_LinIf_00780] ⌈If a positive response needs to be sent for a node configuration request, the LIN Interface shall transmit this response to the next scheduled SRF header.⌋ [SWS_LinIf_00779] ⌈If a valid “Assign NAD” request is received, the LIN Interface shall update its configured NAD value with the new NAD of the request and shall provide a positive response when a SRF header is transmitted by the master node.⌋ [SWS_LinIf_00781] ⌈If a valid “Assign Frame ID range” request is received, the LIN Interface shall update its PID configuration with the PIDs of the request (as defined in the ISO 17987-3 specification) and provide a positive response when a SRF header is transmitted by the master node.⌋ [SWS_LinIf_00809] ⌈It shall not be possible to change the PIDs of frames with identifier 0x3C and 0x3D (MRF and SRF).⌋ [SWS_LinIf_00782] ⌈If a valid “Save Configuration” request is received, the LIN Interface shall call the function <User_SaveConfigurationRequest>. Depending on the return value of this callout function, either a positive response or no response shall be provided.⌋ [SWS_LinIf_00783] ⌈If a valid “Read by Identifier” request with identifier 0 is received, the LIN interface shall provide a positive response to be transmitted for next received SRF header (as defined in the ISO 17987-3 specification).⌋ [SWS_LinIf_00841] ⌈If a valid “Read by Identifier” request with identifier 2 is received, the LIN interface shall provide a negative response to be transmitted for next received SRF header (as defined in the ISO 17987-3 specification).⌋
