图中，输入设备SB1、SB2、FR与PLC内部的“软继电器”X0、X1、X2的“线圈”对应，由输入设备控制相对应的“软继电器”的状态，即通过这些“软继电器”将外部输入设备状态变成PLC内部的状态，这类“软继电器”称为输入继电器；同理，输出设备KM与PLC内部的“软继电器”Y0对应，由“软继电器”Y0状态控制对应的输出设备KM的状态，即通过这些“软继电器”将PLC内部状态输出，以控制外部输出设备，这类“软继电器”称为输出继电器。

因此，PLC用户程序要实现的是：如何用输入继电器X0、X1、X2来控制输出继电器Y0。当控制要求复杂时，程序中还要采用PLC内部的其它类型的“软继电器”，如辅助继电器、定时器、计数器等，以达到控制要求。

要注意的是，PLC等效电路中的继电器并不是实际的物理继电器，它实质上是存储器单元的状态。单元状态为“１”，相当于继电器接通；单元状态为“０”，则相当于继电器断开。因此，我们称这些继电器为“软继电器”。
