ATV650D18N4变频器
③输出对输入的影响有滞后现象。PLC采用集中采样、集中输出的工作方式,当采样阶段结束后,输入状态的变化将要等到下一个采样周期才能被接收,因此这个滞后时间的长短又主要取决于循环周期的长短。此外,影响滞后时间的因素还有输入滤波时间、输出电路的滞后时间等。
④输出映像寄存器的内容取决于用户程序扫描执行的结果。
⑤输出锁存器的内容由上一次输出刷新期间输出映像寄存器中的数据决定。
⑥PLC当前实际的输出状态由输出锁存器的内容决定。

使用方给出的触发脉冲是TTL电平的信号,应在输入隔离变压器前增加接口电路,此接口电路一是为了预放大TTL脉冲信号,二是为了与隔离变压器匹配。为了达到隔离的目的,使用方可提供此接口电路的电源,制造方只需提出电源需求并在电路中设计相应的变换、滤波电路即可。
