2.3 LIN Cluster

A LIN cluster is defined as a number of LIN nodes connected through a physical cable. LIN clusters consist of 1 master and up to 16 slave nodes.The LIN bus connects a single master device (ECU/node) and one or more slave devices (ECU/nodes) together in a LIN cluster. All Signals in a LIN Cluster are defined in the LIN Description File(LDF).

  1. Add LIN cluster→ Short Name → Baudrate(Bits/s) → Protocol Name → Protocol Version → Speed → Save.

  2. LIN Cluster sub points ECU connector, Frame Triggerings and Schedule Table.

2.3.1 ECU Connector

  1. Add ECU → Connector Type (Master or slave) → Connector → PNC Gateway Type(Active,None and Passive)→ Initial Nad → Save.

  2. Connector and controller two parts are there. Controller part Controller Type → Wakeup By Controller Supported (True or false) → Protocol version –> Configured Nad –> Function Id → Supplier Id → variant Id → Save.

2.3.2 Frame Triggering

  1. Add Frame or select Frames (LIN Sporadic Frames, LIN Unconditional Frames and LIN Event Triggered Frames) → Short Name → Frame Type → Identifier → LIN Checksum(Classic and Enhanced) → Tx ECU → Rx ECU →Save.

  2. Frame Triggering Details → ECU Port(Here we select Tx and Rx ECUs) → Frame Details available.
