Network Object Matrix

It’s a network. There are many parameters and system states which are to be tracked. These are abstracted into network objects with unique identifiers. The object identifier is not related to the LINbus node address.

Identifiers are byte/bit based. A bit-encoded quantity can only be retrieved by fetching the byte containing the bit. Any “bonus bits” in the byte will be functionally related to the required bit.

You may recall that each node owns devices which are physically connected to the network through node so the objects are grouped by the node which owns the object.

This matrix is being built sporadically as the nodes are documented so it’s probably incomplete when you read this.

The matrix will also identify the modules that may be “interested” in an object.

When completed, the matrix forms the core of the LINbus master’s management. The bus will however configure itself when nodes are initialised.
