1、细节决定成败，态度决定一切。

2、小事成就大事，细节成就完美。
3、习惯决定成绩，细节决定命运。

4、习惯改变命运，细节铸就终身。

5、细节决定成功，点滴铸就辉煌。

电器（包括时间继电器、电流继电器等）的高集成体,把这些个小继电器的通断看成数字信号，比如小继电器接通为1，断开为0。而模拟信号和数字信号输出则是因为另外添加了信号转换电路和接口电路的结果。它的自动化，就是通过编写PLC可以运行识别的程序语言，对其内的“小继电器”按工厂生产要求进行排列组合设计，控制他们的通断，程序一经运行，就不要认为再去操作，人只要给主电路上的开关都打开，把关键控制点留给PLC就可以了。

2、PCL的链接安装

1】 动力线、控制线以及PLC的电源线和I/O线应分别配线，隔离变压器与PLC和I/O之间应采用双胶线连接。将PLC的IO线和大功率线分开走线，如必须在同一线槽内，分开捆扎交流线、直流线，若条件允许，分槽走线最好，这不仅能使其有尽可能大的空间距离，并能将干扰降到最低限度。 依靠先进的工业网络技术可以迅速有效地收集、传送生产和管理数据。因此，网络在自动化系统集成工程中的重要性越来越显著，甚至有人提出"网络就是控制器"的观点说法。

2】 PLC应远离强干扰源如电焊机、大功率硅整流装置和大型动力设备，不能与高压电器安装在同一个开关柜内。在柜内PLC应远离动力线（二者之间距离应大于200mm）。与PLC装在同一个柜子内的电感性负载，如功率较大的继电器、接触器的线圈，应并联RC消弧电路。开关的操作电源和FTU的工作电源要根据配电网络和设备的具体情况确定，可以从380/220V低压网络直接取得，也可以从10kV线路通过互感器获得;可以采用蓄电池或UPS作为后备电源，也可以从其它配电线路获得后备电源。

3】 PLC的输入与输出最好分开走线，开关量与模拟量也要分开敷设。模拟量信号的传送应采用屏蔽线，屏蔽层应一端或两端接地，接地电阻应小于屏蔽层电阻的1/10.

4】交流输出线和直流输出线不要用同一根电缆，输出线应尽量远离高压线和动力线，避免并行。
