ACHEMA’97展示许多现场总线的应用和基于PROFIBUS—DP,PROFIBUS—PA的器件,介绍的示范系统,展览的产品表明现场总线的技术已成熟,采用现场总线系统不仅经济而且可行,当然还没有能够满足所有用户的要求,远程I/O系统仍在进一步发展和有效地补充现场总线,FF现场总线还要克服一些困难,对其性能需作改进。1、引言近年来,现场总线技术在测量和自动化领域中的应用日益增长,INTERKAMA’92主要仅展示现场总线的一些想法,但在INTERKA-MA’95已展出能实际应用的现场总线技术,如PROFIBUS现场总线用于远程I/O,在芝加哥的ISA’96有FF多供应者现场总线演示系统
ACHEMA’97 showcases a number of fieldbus applications and demonstration systems based on PROFIBUS-DP, PROFIBUS-PA-based devices. The products on display show that fieldbus technology is mature and fieldbus systems are not only economical but also feasible To meet the requirements of all users, the remote I / O system is still further developed and effectively replenished fieldbus, FF fieldbus to overcome some difficulties, its performance needs to be improved. 1. INTRODUCTION In recent years, the application of fieldbus technology in the field of measurement and automation has been increasing. INTERKAMA’92 mainly shows some ideas of fieldbus. However, the fieldbus technology that has been put into practical use on INTERKA-MA’95 has been exhibited. Such as PROFIBUS fieldbus for remote I / O, the FF’s-FF Fieldbus Demonstration System in Chicago’s ISA’96
