摘要
以基金会现场总线为例,对现场总线与传统4～20mA解决方案及其他数字化解决方案的功能进行了客观的比较。从设计习惯和评价标准等角度探讨了现场总线在过程控制领域内获得广泛应用所存在的障碍,进行一步探讨了现场总线对自动化领域内各行各业的影响。
The objective comparison on signal transmission among the fieldbus,traditional 4-20mA and other digital solutions is presented.The application obstacle of FF in process control,which comes from both the designers' custom and the divergent evaluation criterion on fieldbus,is also discussed.Furthermore,the influence of FF in control process and other fields is analyzed.
