摘要
计算机数字通信技术及信息技术的发展,推动了自动化技术的进步;尤其是近年来新兴的现场总线技术(Fieldbus),是计算机数字通信技术向工业自动化领域的延伸,并促使自动化系统结构发生重大变革,必将是传统的基于PLC及DCS控制技术系统发展的必然归宿。
The development of the techniques of computer digital communication and information are propelling the progress of automation technology. The newly developed technology of fieldbus is the extension of computer digital communication to the industrial automation, which would cause great changes in automatic system structure, and will be the end - result of the traditional control system based on PLC and DCS controlling system.
