1．输入接线
1.图形式指令结构：程序由图形方式表达，指令由不同的图形符号组成，易于理解和记忆。系统的软件开发者已把工业控制中所需的独立运算功能编制成象征性图形，用户根据自己的需要把这些图形进行组合，并填入适当的参数。在逻辑运算部分，几乎所有的厂家都采用类似于继电器控制电路的梯形图，很容易接受。如西门子公司还采用控制系统流程图来表示，它沿用二进制逻辑元件图形符号来表达控制关系，很直观易懂。较复杂的算术运算、定时计数等，一般也参照梯形图或逻辑元件图给予表示，虽然象征性不如逻辑运算部分，也受用户欢迎
(1)i/o模块和通讯模块都可带电插拔；

国内plc厂商的服务由公司相关人员去实施，plc生产厂商可以直接面向终用户。由于公司技术人员充分了解自己的产品，能够迅速解决实际应用中发现的问题，因而能显著提高服务水平和服务质量。另外，国内plc厂商可以在plc的售前、售中和售后中为用户提供免费增值服务。例如，面对众多的中小用户，和利时公司开展了免费培训和免费方案设计服务，得到了广大用户的一致好评。
一是变频器启动及运行过程中产生谐波对电网产生传导干扰，引起电网电压畸变，影响电网的供电质量；二是变频器的输出会产生较强的电磁辐射干扰，影响周边设备的正常工作。
