The response time is variable.For example,if an input signal is received immediately before the start of the I/O refresh phase of a scan cycle,the signal will take effect during this cycle.At this time,the response time is the shortest,which is the input delay.time,one scan cycle time,and output delay time;when using direct output refresh,the shortest response time is equal to the sum of input delay time,monitoring time,and output delay time.

响应时间是可变的，例如，在一个扫描周期的I/O刷新阶段开始前瞬间收到一个输入信号，则在本周期内该信号就起作用了，这时响应时间最短，它是输入延迟时间、一个扫描周期时间、输出延迟时间三者之和；在使用直接输出刷新时，最短响应时间等于输入延迟时间、监视时间、输出延迟时间三者之和。
