摘要
Profibus-PA以Profibus DP为基础,增加了PA总线应用行规以及相应的传输技术,使现场总线Profibus能够满足各种过程工业对控制的要求。与传统信号输出方式相比较,Profibus-PA现场总线具有较高的性能价格比、可靠的数据传输、快速的数据响应以及强大的抗干扰能力。结合工程设计实例,探讨了在工程设计中使用Profibus-PA现场总线需注意的事项和基本设计原则。
Profibus-PA, based on Profibus DP, is provided with PA bus application rules and corresponding transmission technology and thus is able to meet various control requirements of process industry. Compared with the traditional signal output mode,Profibus-PA is of high cost performance, reliable data transmission, rapid data response and strong anti-interference ability. The paper discusses dos and don＇ts and basic design principles in utilizing Profibus-PA in engineering design through engineering practice.
