Abstract

estação usuária para um sistema de barramento serial e processo para a comunicação em um sistema de barramento serial. estação usuária (10; 30) para um sistema de barramento serial (1) e a um processo para a comunicação em um sistema de barramento serial (1). a estação usuária (10; 30) tem um dispositivo de controle de comunicação (11; 31) para o controle de uma comunicação estação usuária (10; 30) com pelo menos uma outra estação usuária (10; 20; 30) do sistema de barramento (1), e um dispositivo de transmissão/recepção (12; 32) para a transmissão de um sinal de transmissão (txd) gerado pelo dispositivo de controle de comunicação (11; 31) para um barramento (40) do sistema de barramento (1), de forma que para uma mensagem (45) que seja trocada entre estações usuárias (10, 20, 30) do sistema de barramento (1), o tempo de bit (t_bt) de um sinal transmitido na primeira fase de comunicação (451) para o barramento (40) pode se diferenciar de um tempo de bit (t¬_bt) de um sinal transmitido na segunda fase de comunicação (452), onde o dispositivo de controle de comunicação (11; 31) é configurado para gerar o sinal de transmissão (txd) segundo um quadro (450; 450_1; 4500) e para inserir no quadro 20 (450; 450_1; 4500) ao menos um campo (fcp; fcp_1; fcp-_2) que é configurado para conferir se a corrente de bits do quadro (450; 450_1; 4500) em uma estação usuária (10; 20; 30) do sistema de barramento (1), que recebe o quadro (450; 450_1; 4500), é deslocada em ao menos um bit comparado ao quadro (450; 450_1; 4500) esperado.
