HART协议由Rosemount公司也开
HART协议由Rosemount公司开发且已向每个使用者开放HART协议采用标准的Bell 202频移键控信号以1200波特通信以低电平加载于4mA~20mA模拟信号上,由于载波信号的平均值为零所以它对模拟信号没有影响。-HART agreement develops by Rosemount Corporation also opened
the HART agreement to each user to use the standard the Bell 202
frequency-shift keying signal increase by 1,200 bauds correspondences
by the low level on the 4mA~20mA simulated signal, because
intelligence signal mean value for zero therefore it has not affected
to the simulated signal.
