数字输入多采用变频器面板上的键盘操作和串行接口来给定；模拟输入则通过接线端子由外部给定，通常通过0～10V/5V的电压信号或0/4～20ｍＡ的电流信号输入。由于接口电路因输入信号而异，因此必须根据变频器的输入阻抗选择PLC的输出模块。图5为PLC与变频器之间的信号连接图。 当变频器和PLC的电压信号范围不同时，如变频器的输入信号为0～10V，而PLC的输出电压信号范围为0～5V时；或PLC的一侧的输出信号电压范围为0～10V而变频器的输入电压信号范围为0～5V时，由于变频器和晶体管的允许电压、电流等因素的限制，需用串联的方式接入限流电阻及分压方式，以保证进行开闭时不超过PLC和变频器相应的容量。此外，在连线时还应注意将布线分开，保证主电路一侧的噪音不传到控制电路。 通常变频器也通过接线端子向外部输出相应的监测模拟信号。电信号的范围通常为0～10V/5V及0/4～20ｍＡ电流信号。无论哪种情况，都应注意：PLC一侧的输入阻抗的大小要保证电路中电压和电流不超过电路的允许值，以保证系统的可靠性和减少误差。另外，由于这些监测系统的组成互不相同，有不清楚的地方应向厂家咨询。 另外，在使用PLC进行顺序控制时，由于CPU进行数据处理需要时间，存在一定的时间延迟，故在较精确的控制时应予以考虑。
