摘　　要：随着机电设备的自动化程度的提高,在越来越多的自动化生产线和数控设备中使用了PLC。在对PLC用梯形图编程的过程中,有很强的逻辑关系。其中有一类元器件——辅助继电器,很多人不太擅长使用辅助继电器,如何让大家对辅助继电器理解起来更简单,这是我们要讨论的问题。With the improvement of automation degree of electromechanical equipment, PLC has been used in more and more automatedproduction lines and CNC devices. There is a strong logic relation in the process of PLC ladder programming. There is a type of component - auxiliaryrelay, many people are not very good at using auxiliary relay, how to make people understand the auxiliary relay more simple, this is the problem wehave to discuss.
