<この項は書きかけです。順次追記します。>
文書変更(Document Change)
Changed upper limit of LinTpP2Timing and LinTpP2Max
Renamed the arguments “Schedule” (SWS_LinIf_00202 LinIf_ScheduleRequest) and “schedule” (SWS_LinIf_00520 _ScheduleRequestConfirmat ion)
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 |
