System function

The synchronisation of the LIN bus takes place at the beginning of each message transmitted by the master. This results in a so-called "self-synchronisation" of the data bus without a quartz given clock.

Components on the LIN bus, which correspond to the specifications of the data protocol LIN V2.0 have an extended scope.

• The components for V2.x are delivered with a device id and basic configuration. The final (dynamic) configuration and the allocation of the identification number takes place during the start-up via the master control unit.
• The data protocol has become more variable. As of specification V2.0, if desired, sporatic messages are also permitted in addition to the periodic messages.
• The master control units can transmit so-called multiple queries to a group of slaves. In order to reduce the load on the data bus, the addressed slaves only respond when values are modified (e.g. door contact).
