Abstract: There was a great domestic market demand for digital output nodes, but most equipment supplies depended on abroad market. In view of this, the design processes of digital output node based on LonWorks technology were introduced, including power source, memory extended interface, I/O interface, communication interface, reset circuit, server circuit, clock circuit and Neuron C programming. Antiinterference measures of node and performance optimizing methods of node were also discussed. The experimental results indicate that digital output node can provide the normal operation and meet requirements for common application systems.
Key words: LonWorks; digital output node; design on hardware and software; antiinterference; performance optimization
