随着过程控制行业信息化的高速发展,数字化电厂已成为今后新建电厂的发展趋势,双向数字通信的现场总线控制技术作为数字化电厂的基础,近年来已逐渐融入到电厂之中,但是作为新技术,现场总线的应用也必将会出现相应的问题。文章举例讲述通过对Profibus报文的分析处理现场总线设备所出现的通信问题,以供参考。
With the rapid development of information technology in the process control industry, digital power plants have become the development trend of new power plants in the future. The field bus control technology of bidirectional digital communications, as the basis of digital power plants, has been gradually integrated into power plants in recent years. However, as a new technology , The application of field bus will also appear the corresponding problem. The article gives an example to illustrate the communication problem that emerges from the analysis of Profibus telegrams to the fieldbus devices for reference.
