　　控制器

　　控制器是指按照预定顺序改变主电路或控制电路的接线和 改变电路中电阻值来控制电动机的启动、调速、制动与反向的主令装置。控制器由程序状态寄存器PSR，系统状态寄存器SSR， 程序计数器PC，指令寄存器等组成，其作为“决策机构”，主要任务就是发布命令，发挥着整个计算机系统操作的协调与指挥作用。 控制的分类主要包括两种，分别为组合逻辑控制器、微程序控制器，两个部分都有各自的优点与不足。其中组合逻辑控制器结构相对较复杂，但优点是速度较快；微程序控制器设计的结构简单，但在修改一条机器指令功能中，需对微程序的全部重编。

　　在输入采样阶段，可编程逻辑控制器以扫描方式依次地读入所有输入状态和数据，并将它们存入I/O映象区中的相应的单元内。输入采样结束后，转入用户程序执行和输出刷新阶段。在这两个阶段中，即使输入状态和数据发生变化，I/O映象区中的相应单元的状态和数据也不会改变。因此，如果输入是脉冲信号，则该脉冲信号的宽度必须大于一个扫描周期，才能保证在任何情况下，该输入均能被读入

　　(1)可靠性高。由于PLC大都采用单片微型计算机，因而集成度高，再加上相应的保护电路及自诊断功能，提高了系统的可靠性。

　　(2)编程容易。PLC的编程多采用继电器控制梯形图及命令语句，其数量比微型机指令要少得多，除中、高档PLC外，一般的小型PLC只有16条左右。由于梯形图形象而简单，因此容易掌握、使用方便，甚至不需要计算机知识，就可进行编程。

　　(3)组态灵活。由于PLC采用积木式结构，用户只需要简单地组合，便可灵活地改变控制系统的功能和规模，因此，可适用于任何控制系统。

　　The controller refers to the master device that controls the starting, speed regulation, braking and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to the predetermined sequence. The controller is composed of program status register PSR, system status register SSR, program counter PC, instruction register, etc. as a "decision-making body", its main task is to issue commands and play a coordinating and commanding role in the operation of the whole computer system. The classification of control mainly includes two kinds, namely, combinational logic controller and microprogrammed controller. Both parts have their own advantages and disadvantages. The structure of combinational logic controller is relatively complex, but its advantage is that its speed is faster; The structure of the microprogramming controller is simple, but in modifying a machine instruction function, it is necessary to reprogram all the microprograms.

　　In the input sampling phase, the programmable logic controller reads in all input states and data in sequence by scanning, and stores them in the corresponding units in the i/o image area. After the input sampling is completed, it will enter the user program execution and output refresh phase. In these two stages, even if the input state and data change, the state and data of the corresponding unit in the i/o image area will not change. Therefore, if the input is a pulse **, the width of the pulse ** must be greater than one scanning cycle to ensure that the input can be read in under any circumstances

　　(1) High reliability. Because PLC mostly adopts single-chip microcomputer, it has a high degree of integration. In addition, the corresponding protection circuit and self diagnosis function improve the reliability of the system.

　　(2) Easy programming. The programming of PLC mostly adopts relay control ladder diagram and command statements, and its number is much less than that of microcomputer instructions. Except for medium and high-grade PLC, there are only about 16 general small PLC. Because the ladder diagram is vivid and simple, it is easy to master and use, and it can be programmed without computer professional knowledge.

　　(3) Flexible configuration. Because PLC adopts building block structure, users can flexibly change the function and scale of the control system by simply combining. Therefore, it can be applied to any control system.
