q 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。
