Resumo: | A flexible real-time communication system must support modifications to the message set which it conveys. These changes can be requested by a human operator, during system set-up or maintenance, or autonomously bythe control system while responding to variations in theenvironment. In the former case, a response time up to a few seconds can be acceptable. However, in the latter, thephysical properties of the environment can require thatchanges to the message set are carried out in a short term. In this case, a response time in the order of a few milliseconds can be demanded. In this paper we analyse the responsiveness of the FTTCANprotocol, in particular of its synchronous messaging system. Then, a method is proposed to improve such responsiveness with regard to urgent requests for changes in the message set. |

Estas modificações podem ser solicitadas por um operador humano, durante a configuração ou manutenção do sistema, ou autonomamente pelo sistema de controlo, quando responde a alterações no sistema controlado. No primeiro caso, um tempo de resposta até alguns segundos pode ser aceite. Todavia, no segundo caso, as propriedades físicas do sistema controlado podem exigir que as mudanças ao conjunto de mensagens sejam executadas num prazo mais curto. Em alguns casos poderá ser necessário um tempo de resposta da ordem de milisegundos. Neste artigo, analisamos a reactividade do protocolo FTTCAN, em particular do seu sistema de mensagens síncronas. Em seguida apresentamos um método para melhorar essa reactividade face a pedidos de alterações com requisitos temporais urgentes.UA Editora2000-01-01T00:00:00Zjournal articleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://proa.ua.pt/index.php/revdeti/article/view/18303oai:proa.ua.pt:article/18303Eletrónica e Telecomunicações; Vol 3 No 2 (2000); 108-112Eletrónica e Telecomunicações; vol. 3 n.º 2 (2000); 108-1122182-97721645-0493reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPenghttps://proa.ua.pt/index.php/revdeti/article/view/18303https://proa.ua.pt/index.php/revdeti/article/view/18303/13197https://creativecommons.org/licenses/by/4.0/info:eu-repo/semantics/openAccessPedreiras, P.Almeida, L.Fonseca, J.

These changes can be requested by a human operator, during system set-up or maintenance, or autonomously bythe control system while responding to variations in theenvironment. In the former case, a response time up to a few seconds can be acceptable. However, in the latter, thephysical properties of the environment can require thatchanges to the message set are carried out in a short term. In this case, a response time in the order of a few milliseconds can be demanded. In this paper we analyse the responsiveness of the FTTCANprotocol, in particular of its synchronous messaging system. Then, a method is proposed to improve such responsiveness with regard to urgent requests for changes in the message set. |
