Abstract

The invention is in order to solves existing circumstance that researching on I/O object at home and abroad is focus on application, and issues such as how to build communication relation between I/O object and network variable as well as how to compare and display data of communication have not solved yet. LonWorks bus interfaces of first transceiver and second transceiver in the system are connected to LonWorks bus. The method includes steps: staring up and initializing sending node and receiving node, and binding network variable of each node; using code dialed switch A with eight routes inputs a transmission reference value, and then the send button is pressed; using code dialed switch B with eight routes inputs a value again, and then the send button is pressed; repeating the said step for ten times, ending, the invention can implement communication of LonWorks I/O under different transmission condition, as well as can carry out comparison and display.

Description

technical field [0001] The invention relates to the technical field of communication and display of LonWorks I / O objects under different transmission conditions. Background technique [0002] With the emergence of thousands of application developers and the installation of millions of devices around the world, the LonWorks system has become the leading open solution for building automation, industry, transportation and public equipment control networks. The 11 pins (application I / O) of the neuron chip in the LonWorks technology can be configured into various working modes, so as to realize flexible input and output functions with the smallest external circuit. At present, the research on I / O objects at home and abroad focuses on its application, and mainly studies the hardware and software implementation of different objects. Since the neuron chip has both communication and control functions, how to establish a communication relationship between its I / O objects and network ...
