《电子技术应用》1987年第2期刊登的“在过程控制中应用Z80-CTC定时的小经验”一文中曾谈到CTC的应用,共中以通道O为定时工作状态,通道1、2、3.为计数工作状态。通道O定时时间为20mS,通道12、3计数常数分别为2、3、4。这样,对四个参数的采样时间为20mS、40mS、60mS和80mS。并且,为避 The application of CTC was mentioned in the article “Application of Z80-CTC Timing in Process Control” published by “Application of Electronic Technology”, No. 2, 1987, in which the channel O is the regular working state and the channels 1, 2, 3. To count the working status. Channel O timing time of 20mS, channel 12,3 count constants were 2,3,4. Thus, the sampling time for the four parameters is 20mS, 40mS, 60mS and 80mS. And, to avoid
