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。

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。

编程器——PLC开发应用、监测运行、检查维护不可缺少的工具
根据工作功能图表或状态流程图等设计出梯形图即编程。这一步是整个应用系统设计的核心工作，也是比较困难的一步，要设计好梯形图，首先要十分熟悉控制要求，同时还要有一定的电气设计的实践经验
以超小型PLC为例，新近出产的品种底部尺寸小于100mm，重量小于150g，功耗仅数瓦。由于体积小很容易装入机械内部，是实现机电一体化的理想控制设备。

一个新的控制工程固然能提高产品的质量和数量，带来巨大的经济效益和社会效益，但新工程的投入、技术的培训、设备的维护也将导致运行资金的增加。因此，在满足控制要求的前提下，一方面要注意不断地扩大工程的效益，另一方面也要注意不断地降低工程的成本。这就要求设计者不仅应该使控制系统简单、经济，而且要使控制系统的使用和维护方便、成本低，不宜盲目追求自动化和高指标。

系统接地方式有：浮地方式、直接接地方式和电容接地三种方式。对PLC控制系统而言，它属高速低电平控制装置，应采用直接接地方式。由于信号电缆分布电容和输入装置滤波等的影响，装置之间的信号交换频率一般都低于1MHz，所以PLC控制系统接地线采用一点接地和串联一点接地方式。集中布置的PLC系统适于并联一点接地方式，各装置的柜体中心接地点以单独的接地线引向接地极。如果装置间距较大，应采用串联一点接地方式。用一根大截面铜母线（或绝缘电缆）连接各装置的柜体中心接地点，然后将接地母线直接连接接地极。接地线采用截面大于22mm2的铜导线，总母线使用截面大于60mm2的铜排。接地极的接地电阻小于2Ω，接地极**埋在距建筑物10~15m远处，而且PLC系统接地点必须与强电设备接地点相距10m以上。
