为了处理急需响应的输入信号，PLC有种种措施。不同的PLC措施也不完全相同，提高响应速度的效果也不同。一般的作法是采用输入中断，然后再输出即时刷新，即中断程序运行后，有关的输出点立即刷新，而不等到整个程序运行结束后再刷新。
这个效果可从两个方面来衡量：一是能否对几个输入信号作快速响应；二是快速响应的速度有多快。多数PLC都可对一个或多个输入点作快速响应，快速响应时间仅几个毫秒。性能高的、大型的PLC响应点数更多。
工作速度关系到PLC对输入信号的响应速度，是PLC对系统控制是否及时的前提。控制不及时，就不可能准确与可靠，特别是对一些需作快速响应的系统。这就是把工作速度作为PLC第一指标的原因。
