文書変更(Document Change)

• Added Extended Production Errors regarding LinTp timeouts and relevant errors
• Added a note after [SWS_LinIf_00503] for clarification on implementation of LinIf_CheckWakeup API
• Clarification of “Available via: Configurable” in API tables (Header File Cleanup)
• Refined configuration structure
• Editorial changes (incl. correcting typos in spec. items)

用語(terms)

term	Description
CF	Continuous Frame in LIN TP
FF	First Frame in LIN TP
ID	Identifier
LDF	LIN Description File
LIN TP	LIN Transport Protocol (Part of the LIN Interface)
MRF	Master Request Frame
NAD	Node Address. Each slave in LIN must have a unique NAD.
NC	Node Configuration
N_As	Time for transmission of the LIN frame (any N-PDU) on the sender side (see ISO 17987-2 [19]).
N_Cr	Time until reception of the next consecutive frame N-PDU (see ISO 17987-2 [19]).
N_Cs	Time until transmission of the next consecutive frame N-PDU (see ISO 17987-2 [19]).
P2	Time between reception of the last frame of a diagnostic request on the LIN bus and the slave node being able to provide data for a response.
P2*	Time between sending a response pending frame (0x78) and the LIN-slave being able to provide data for a response.
PID	Protected ID
RX	Reception
SID	Service Identifier (of node configuration service)
SF	Single Frame in LIN TP
SRF	Slave Response Frame
SRS	Software Requirement Specification
TX	Transmission
Slot Delay	The time between start of frames in a schedule table. The unit is in number of time-bases for the specific cluster.
Jitter	Difference between longest delay and shortest delay (e.g. Worst case execution time – Best case execution time)
Maximum frame length	The maximum frame length is the TFRAME_MAX as defined in the ISO 17987-3 [19] (i.e. The nominal frame length plus 40 %).
Schedule entry is due	This means that the LIN Interface has arrived at a new entry in the schedule table and a frame (received or transmitted) will be initiated.
Slave-to-slave	From a LIN master node’s point of view, there exist 3 different directions of frames on the LIN bus: Response transmitted by the master, Response received by the master and Response transmitted by one slave and received by another slave. The slave-to-slave is describing the last one. This is not described explicitly in the ISO 17987 specifications, but mentioned in Figure 14 in ISO 17987-3: Three unconditional frame transfers.
Irrelevant frame	From a LIN slave node point of view, there exist 3 different directions of frames on the LIN bus: Response transmitted by the slave, Response received by the slave and Response that is ignored by the slave (i.e. communication between master and another slave or between two other slaves). These ignored frames are named irrelevant frames in this specification. This is not described explicitly in the ISO17987 specifications.
Relevant frame	From a LIN slave node point of view, a frame that is transmitted or received by the slave. Opposite of irrelevant frame.
Sporadic frame	This is one of the unconditional frames that are attached to a sporadic slot.
Sporadic slot	This is a placeholder for the sporadic frames. The reason to name it slot is that it has no LIN frame ID.
Tick	The tick is the smallest time entity to handle the communication on all channels.
Bus idle timeout	Lapse of time duration with no bus activity
