| Abstract: | To solve the problem of communication of distributed control system,the design and implementation of the parallel communication based on ISA bus and first-in first-out (FIFO)technology are introduced.The principle of an asynchronous and parallel technique is presented,and its circuit design and software are detailed presented.The commu-nication card feature simple protocol,long distance of communication,bulk data transfer and good real time performance. |
