Q Q ：1093230189在PLC控制系统设计中,常常碰到负载的起动与停止控制,通常的做法是采用两只按钮作为外部起动与停止控制的输入器件, 在PLC中与两只按钮相对应的输入点数也有两个，PLC的外部接线如图1所示，按钮SB1（X0）作为起动控制，按钮SB2（X1）作为停止控制，这样虽然可以达到控制目的,但需要的按钮和连接导线较多,PLC的输入点数也较多。但在实际工作中，可以充分利用PLC内部多功能化的特点，采用单个按钮控制负载的起动与停止，进行改进后的PLC外部接线如图2所示，用SB替代SB1 和SB2的功能，用X0替代X0和X1的功能，电路的实际接线就大大简化，这样做不仅节省了硬件成本,而且还大大减少了由于按钮多而可能引起的故障.使电路更加经济合理、安全可靠，控制方便简单，具有很高的实用价值。笔者根据实际的工作经验和研究成果，以松下电工FP0系列PLC为例介绍几种单按钮起停控制的PLC编程技术。 [align=center] 图1 图2[/align] 1 采用上升沿微分指令的编程技术 [align=center] 图3 采用上升沿微分指令编程的梯形图程序 图4采用置位/复位指令编程的梯形图程序[/align] 采用上升沿微分指令编程的梯形图程序，如图3所示，控制过程如下： 当第一次按下SB时，X0接通，使R0的线圈接通一个扫描周期，其常开触点闭合，Y0的线圈接通并自锁，启动外部负载工作运行；同时，Y0的对常开触点闭合，为R1的线圈接通做准备；当第2次按下按钮SB时，X0接通，R0再次接通一个扫描周期，R1的线圈被接通，R1的常闭触点分断，Y0的线圈断开，外部负载停止工作。反复按下SB，将会重复上述控制过程。 采用置位/复位指令的编程技术 采用置位/复位指令编程的梯形图程序，如图4所示，控制过程如下： 当按下SB时，X0接通，R0的线圈接通一个扫描周期，其常开触点闭合，R2置位（闭合）且保持，R2的一对常开触点闭合，Y0的线圈接通，启动外部负载工作运行；同时，R2的另一对常开接点闭合，为R1的线圈接通做准备；当再次按下SB时，X0接通，使R0的线圈再次接通一个扫描周期，R1的线圈接通，R1的常开接点闭合，R2复位（断开）且保持,Y0的线圈断开，外部负载停止工作运行。之后依次按下SB的工作情形与上述相同。
