FF协议是一种美式的浪漫主义标准，在美国多增加二十美金的成本对于一个控制器或者传感器来说并不是什么大不了的，但对于广大的第三世界国家，短时间内我们是不太可能接受这么贵的解决方案，而且技术上面也存在着很多的理想化，目前也只有H1在使用，H2已完全废弃，改用工业以太网。每当我看到FF后，总让我想起LONWORKS，我应该是国内比较早用LONWORKS开发产品的研发工程师，2000年我们对LON协议充满了好感，特别是它的人化的设计、七层协议的完整实现、基于网络变量的组态方式。但在后来若干年中，我们有一种骑虎难下来感觉。1、LON协议太慢了，一个74K网络中一秒多也不过几十帧;2、协议实现不完整，FT-10A的收发器根本就没有实现P坚持型载波侦听多路访问协议(P—CSMA)，所谓的回避就是减少每一秒钟的发送数据帧数，然后每一帧发三次，这是做了很多实验后再打电话给美国Echtelon公司后得到的正式答复FT-10A不支持LON协议的P—CSMA;3、LON的芯片3150其实是一颗早期摩托罗拉的三核，这确实为通信能力的提升带来了很多好处，但仍然不是硬件解析的，所以速度相当慢;4、基于LONMARK的组态软件使用户在现场很难维护，换任一节点后都需要重新组态和配置，并且过程相当麻烦和缓慢（可能现在的电脑速度上会快很多)，这在工控现场是不可思议的;

FF protocol is an American romantic standard, in the United States to increase the cost of 20 dollars for a controller or sensor is not a big deal, but for the vast number of third world countries, we are unlikely to accept such an expensive solution in a short time, and there are a lot of idealization of the technology, currently only H1 in use. H2 has been completely abandoned in favor of industrial Ethernet. Whenever I see FF, it always reminds me of LONWORKS. I should be a research and development engineer who used LONWORKS to develop products earlier in China. In 2000, we were full of good feelings for LON protocol, especially its humanized design, complete implementation of seven-layer protocol, and configuration mode based on network variables. But in the years that followed, there was a sense that we were riding the tiger. 1, LON protocol is too slow, a 74K network more than a few dozen frames a second; 2, the protocol implementation is not complete, FT-10A transceiver does not implement P-persistence carrier sense multiple access protocol (P-CSMA), the so-called avoidance is to reduce the number of data frames sent per second, and then three times per frame. This was the official answer after many experiments and a call to Echtelon USA that FT-10A did not support the LON protocol P-CSMA; 3, LON's chip 3150 is actually an early MOTOROLA three-core, which does bring a lot of benefits for the improvement of communication capabilities, but it is still not hardware analysis, so the speed is quite slow; 4, based on LONMARK configuration software users in the field is difficult to maintain, change any node after the need to reconfigure and configure, and the process is quite troublesome and slow (may now the computer speed will be much faster), which is incredible in the industrial control site;
