Can Controller Area Network

Comunicação industrial; rede sem fio; wireless. ABSTRACT Currently, industrial communication networks are a fundamental part in industrial processes. The great development of industry is due to the fact that there are real-time communication between devices and control rooms, which can be solved problems that may occur without great loss of time, increasing production. Wireless networks present themselves as a great evolution of communication, once used for…

grid may have environmental benefits, but the deployment of offshore transmission of bulk electrical power to or from offshore platforms to the electrical grid onshore is a mayor challenge. The main objective of this paper is to focus on trends that can lead to a feasible transmission system in offshore energy systems far from land, and to introduce the technological alternatives which could help to reach that goal. The paper describes the main alternatives and the technical and…

(2000), pode-se definir o microcontrolador como um “pequeno” componente eletrônico, dotado de uma “inteligência” programável, utilizando no controle de processos lógicos. De acordo com Pereira (2002), os microcontroladores PIC (Peripheral Interface Controller) são uma família de dispositivos fabricados pela Microchip. Utilizando uma arquitetura RISC (Reduced Instruction Set Computer), com frequências de clock de até 40 Mhz, até 2048 Word de memória de programa e até 3968 bytes de…

Deve circular pelos intervenientes que devem ser activos na sua revisão • Deve ser analisada de forma quantitativa • Deve permitir escolher um primeiro esqueleto de implementação • Com a arquitectura deve resultar claro o conjunto de áreas críticas (rede, memória) e a sua resolução • Deve definir módulos com responsabilidades funcionais claras • Os módulos devem ter um interface bem definido • A arquitectura não deve depender de uma determinada versão de um produto

architecture frameworks for further information. In 1992, Steven Spewak described a process for creating an enterprise architecture that is widely used in educational courses.[8] 2 Areas of practice Several enterprise architecture frameworks break down the practice of enterprise architecture into a number of practice areas or "domains". In his book on Enterprise Architecture, Spewak divides the practice into two domains at 'level 2': "Business Modelling" and "Current Systems and…

this task easier and more efficient by concentrating several careers’ worth of equipment-building experience into a single volume – a thoroughly revised and updated edition of a 25-year-old classic. Covering areas ranging from glassblowing to electron optics and from temperature controllers to lasers, the invaluable information in this book is destined to save years of collective frustration for students and scientists. It is a ‘‘must-have’’ on the shelf of every research lab.…

Se fôssemos root, neste caso, iria funcionar. lsof – Listar arquivos abertos Sintaxe: $ lsof [opções] [arquivo] O comando lsof é um dos mais importantes comandos para quem administra sistemas Linux, principalmente na área de segurança. Este comando lista todos os arquivos abertos por todos os processos. Aqui, quando eu falo arquivo, não são apenas arquivos comuns, mas sim recursos que funcionam como arquivos (podem ser abertos, mapeados na memória,…

had in Recife. Many thanks to Rev. Edmilson Marinho, his wife Ilza, and their children Priscila and Gabriel, for their support and friendship. iv Abstract The problem to be addressed in this thesis is expressed in the following question: can a specification be translated into a computer program, in such a way that it executes in a group of processors with all specified constraints satisfied? This work considers embedded hard real-time systems development methodologies, more specifically
