数据采集可以用计数器，累计记录采集到的脉冲数，并定时地转存到DM区中去。
数据采集也可用A/D单元，当模拟量转换成数字量后，再定时地转存到DM区中去。
PLC还可配置上小型打印机，定期把DM区的数据打出来。
PLC也可与计算机通讯，由计算机把DM区的数据读出，并由计算机再对这些数据作处理。这时，PLC即成为计算机的数据终端。
电力用户曾使用PLC，用以实时记录用户用电情况，以实现不同用电时间、不同计价的收费办法，鼓励用户在用电低谷时多用电，达到合理用电与节约用电的目的。
PLC自检信号很多，内部器件也很多，多数使用者未充分发挥其作用。
其实，完全可利用它进行PLC自身工作的监控，或对控制对象进行监控。
这里介绍一种用PLC定时器作看门狗，对控制对象工作情况进行监控的思路。
如用PLC控制某运动部件动作，看施加控制后动作进行了没有，可用看门狗办法实现监控。具体作法是在施加控制的同时，令看门狗定时器计时。如在规定的时间内动作完成，即定时器未超过警戒值的情况下，已收到动作完成信号，则说明控制对象工作正常，无需报警。
若超时，说明不正常，可作相应处理。
如果控制对象的各重要控制环节，都用这样一些看门狗"看"着，那系统的工作将了如指掌，出现了问题，卡在什么环节上也很好查找。
还有其它一些监控工作可做。对一个复杂的控制系统，特别是自动控制系统，监控以至进一步能自诊断是非常必要的。它可减少系统的故障，出了故障也好查找，可提高累计平均无故障运行时间，降低故障修复时间，提高系统的可靠性。
