（四）分配i/o点并设计plc外围硬件线路
因为plc本身的故障可能性极小，系统的故障主要来自外围的元部件，所以它的故障可分为如下几种：
（1）输入采样阶段。在这一阶段中，plc以扫描方式读入所有输入端子上的输入信号，并将各输入状态存入对应的输入映像寄存器中。此时，输入映像寄存器被刷断。在程序执行阶段和输出刷新阶段中，输入映像存储器与外界隔离，其内容保持不变，直至下一个扫描周期的输入扫描阶段，才被重新读入的输入信号刷新。可见，plc在执行程序和处理数据时，不直接使用现场当时的输入信号，而使用本次采样时输入到映像区中的数据。一般来说，输入信号的宽度要大于一个扫描周期，否则可能造成信号的丢失。
编程器——plc开发应用、监测运行、检查维护不可缺少的工具
plc的硬件配置、控制程序采用施奈德的编程软件包unitypro完成，pc通过网络或usb与m340plc进行程序传送。首先进行plc硬件组态，含底版、电源、cpu、输入输出模块等。通过电源模块属性可查看电源使用情况，应保留一定余量，否则需更换容量更大的电源模块；在cpu模块的serialport口配置串行链路参数如：485modbus主站、波特率9600、帧延时4ms、数据位8位、停止位1位、偶校验；创建网络链路ethernet1并配置ip地址等网络通信参数，将cpu模块的ethernet口链接到网络链路ethernet1；根据现场模拟量信号要求配置模拟量输出模块参数；定义相关变量等。
国内plc厂商能够确切了解中国用户的需求，并适时地根据中国用户的要求开发、生产适销对路的plc产品。例如，和利时公司具有12年的控制类产品生产、销售及工程实施经验，积累了大量客户资源，了解国内不同行业、不同地区、不同所有制用户的真正需求，因此在产品设计时可以充分考虑中国用户的需求和使用习惯，产品的针对性和易用性更强。
