PLC点阵键盘
在工控行业中，有时候会碰到因为可编程控制器（PLC）输入点的不够，而导致需要更换设备，浪费资源。对此，当实时性不需要那么高时，我们可以编写一个键盘的扫描程序来扩展输入的点数。因为扫描的方式是循环扫描，所以在实时性方面会有一定的欠缺。
下面是用海为PLC编程软件编写的8乘6的48键扫描程序。需要用到8个输入点，6个输出点，硬件连接如下图所示：
注：当要求实现组合按键时上图的二极管必须加，反之二极管可加可不加。
扫描的点是令Y0~Y5循环输出，当有按钮按下时，就会做出相应的动作，例如：当按钮键0按下时，则X0接通，当程序扫描到Y0时，X0与Y0形成一个回路， 表示按键“0”按下。程序如下图所示：
结论：键盘是以循环扫描的方式来进行输入，而扫描的时间越短则实时性越好。但是当扫描时间过短时会因Y0~Y5输出结束时，X0仍未接通导致无法产生输出信号。或者当Y0输出结束，Y1也输出结束时，X0仍未断开，导致误判断。
经过型号SW-S32ZS220T测试可知每次循环扫描的时间T0不得低于20ms。建议可将滤波时间设得短一点，则可以缩短每次循环扫描的时间T0，例如：本例中将滤波时间设为0.8ms，则每次循环扫描的时间T0可以设到***短10ms。
