不管输入单元的LED灯亮还是灭，请检查输入信号开关是否确实在ON或OFF状态。如果输入开关的额定电流容量过大或由于油侵入等原因，容易产生接触不良。当输入开关与LED灯亮用电阻并联时，即使输入开关OFF但并联电路仍导通，仍可对PLC进行输入。如果使用光传感器等输入设备，由于发光／受光部位粘有污垢等，引起灵敏度变化，有可能不能完全进入“ON”状态。在比PLC运算**的时间内，不能接收到ON和OFF的输入。如果在输入端子上外加不同的电压时，会损坏输入回路。
将光纤传感器放大器单元中与光纤单元相连接的一侧的钩爪嵌入固定导轨后，再压下直到挂钩完全锁定，如图1所示。
电源模块选择仅对于模块式结构的PLC而言，对于整体式PLC不存在电源的选择。
１、顺序控制
如今，许多过程自动化系统（包括许多安装在新工厂的系统）采用了大量的定制，并且饱受项目延误和成本超支带来的影响。他们与工厂**、生产计划管理等许多MOM应用的集成性也很差。其中的许多系统也受到人为阻碍，无法为有需要的人员和应用程序提供开放式的信息流。CPAS探讨了许多原则，如果遵循这些原则将有助于消除这些阻碍。
PLCopen运动控制规范的第四部分包含了可以协调运动控制的功能块，对其和第二部分在三维空间多轴运动控制的协调功能进行了扩展，以满足在此领域中绝大部分的应用需求。它们定义了一套标准的功能块，可在三维空间内应用于复杂的运动控制，包括运动转变功能块。一般情况下，这些转变功能块由供应商提供，所以对大多数生产制造商而言，如果运动控制器不支持，则不能添加此功能。目前获得支持的主要是SCARA和DELTA机器人。此外，任何编程人员都可以编程实现自己的运动转换功能。当需要将实际位置转换为关节空间，或者将关节空间转换为实际位置时，专用程序就可以调用这些运动程序。
