摘　　要：PLC技术应用中 ,时间顺序循环控制程序设计经常出现的错误是 :不能实现TIM控制的顺序动作和循环控制。因此 ,正确设计基本的时间顺序循环控制程序应注意I/O点、辅助点继电器线圈及TIM动作原理和动作条件 ;设置合理控制触点 。In the application of PLC Technology, the frequent faults in the program design of PLC time sequence and cycle control are that sequence act and cycle control controlled by TIM can′t be implemented. Therefore, proper program design of sequence and cycle control should notice as follows:make I/O point、coil of relay of auxiliary point and act principle and act condition of TIM definite; set up equitable control contract, make designed program implement sequence control and cycle control controlled by TIM.
