【摘要】 在自动控制系统的调试过程中,系统投入运行后发现控制工艺过程与设计的控制时序不一致。这可能与扫描周期和响应时间、硬件复位、内部硬件电路设计有关,可设法从几个方面寻求排除故障的途径。更多还原

【Abstract】 There is a case in testing a control system that the control program is all right but the system does not works correctly. This probably because the problem about scan cycle, hardware rest and interior relay. We can solve problem from this way.更多还原
