摘要
本文阐述了IEC61158.2和GB/T20540.2对Profibus现场总线电缆的要求,并归纳出了5个国外公司相关产品的结构与性能。通过电气参数的计算对其性能及要求作了深入的说明,并针对常见的5种不同使用场所要求,提出相应的解决方法。最后希望尽快出台我们国家的现场总线电缆标准,实现该产品的全面国产化。
This article expatiates the requirements for Profibus cables in IEC61158. 2 and GB/T 20540.2, and specify the structures and characteristics of correlative products introduced by 5 enterprises overseas. Deeper explanations are made via calculation of electric parameters for Profibus cables and solutions are put forward to five different applied location. Finally, hope our Chinese Profibus cables standards should be issued as soon as possible in order to implement the overall localization.
