Because of the limit in modern industry sites, the frequency of the process variables detect is different. We can resolve the problem by multi frequency and multivariablecontrol.
在工业现场由于条件的限制,很多过程变量需要的检测频率并不一样,从而带来了多频多变量的控制问题。

The problems are:the storage of cumulating variable at power off, multi-byte division, the detection of rotating speed and the control of facilities by AC power.
这几个问题是:累积量的掉电存储问题、多字节除法问题、转速的检测问题和交流电设备的控制问题。
