1756-M02AE 软启动器
这是一种模仿继电器控制系统的编程方法。其图形甚至元件名称都与继电器控制电路十分相近。这种方法很容易地就可以把原继电器控制电路移植成 PLC 的梯形图语言。这对于熟悉继电器控制的人来说,是 方便的一种编程方法。 PLC的指令繁多,但主要的有这么几种类型: 基本逻辑指令,用于处理逻辑关系,以实现逻辑控制。这类指令不管什么样的PLC都总是有的。 数据处理指令,用于处理数据,如译码,编码,传送、移位等等。 数据运算指令,用于进数据的运算,如十、一、X、/等,可进行整形数计算,有的还可浮点数运算;也可进行逻辑量运算,等等。 流程控制指令,用以控制程序运行流程。PLC的用户程序一般是从零地址的指令开始执行,按顺序推进。但遇到流程控制指令也可作相应改变。流程控制指令也较多,运用得好,可使程序简练,并便于调试与阅读。 状态监控指令,用以监视及记录PLC及其控制系统的工作状态,对PLC控制系统的工作可靠性大有帮助。 当然,并不是所有的PLC都有上述那么多类的指令,也不是有的PLC仅有上述几类指令。以上只是指出几个例子,说明要从哪几个方面了解PLC指令,从中也可大致看出指令的多少及功能将怎样影响PLC的性能。 除了指令,为进行通讯,PLC还有相应的协议与通讯指令或命令,这些也反映了PLC的性能。 6支持软件 为了便于编制PLC程序
