Abstract

"IDENTIFICADORES DE Nó DE DOIS NìVEIS NO PROTOCOLO DE REDE DE áREA DE CONTROLE (CAN)". O campo identificador de 29 bits de um formato de mensagem do protocolo CAN é subdividido em uma parte de função da mensagem, uma parte identificadora de nó da classe um, para identificar os nós da classe um que devem estar aptos a se comunicar com cada outro bem como com um grande número de outros nós no sistema e uma parte identificadora de nó que pode ser selecionada, a grande maioria da qual é utilizada para identificadores de nó da classe dois, para identificar nós da classe dois que nunca necessitam se comunicar um com o outro, mas somente necessitam se comunicar com os nós da classe um e uma pequena parte da qual é utilizada para os identificadores de nó da classe um para casos onde dois nós da classe um estão se comunicando um com o outro. Os oito bits menos significativos da parte que pode ser selecionada representam identificadores da classe um quando os oito bits mais significativos da parte que pode ser selecionada são todos zeros, mas quando qualquer um dos oito bits mais significativos da parte que pode ser selecionada representa um um, então os oito bits ordenados mais baixos são parte de um identificador da classe dois. Portanto, a parte que pode ser selecionada pode identificar, por exemplo, 256 nós da classe um e 65.280 nós da classe dois.
