控制器的作用是控制和协调整个计算机的动作，控制通常需要程序计数器PC、指令存放器IR、指令译码器ID、定时与控制电路，以及脉冲源、中断等共同完成。控制器由：指令存放器Instruction Register、指令译码器Instruction Decoder、定时与控制电路Programmable Logic Array、程序计数器Program Counter、标志存放器Flags Register、堆栈和堆栈指针Stack Pointer、存放器组等构成。控制器的主要功能：运算器只能完成运算，而控制器用于控制着整个CPU的工作。指令控制器：指令控制器是控制器中相当重要的局部，它要完成取指令、分析指令等操作，然后交给执行单元ALU或FPU来执行，同时还要形成下一条指令的地址。

时序控制器:时序控制器的作用是为每条指令按时间顺序提供控制信号。时序控制器包括时钟发生器和倍频定义单元，其中时钟发生器由石英晶体振荡器发出非常稳定的脉冲信号，就是CPU的主频；而倍频定义单元那么定义了CPU主频是存储器频率总线频率的几倍。总线控制器：总线控制器主要用于控制CPU的内外部总线，包括地址总线、数据总线、控制总线等等。

The function of a controller is to control and coordinate the actions of the entire computer. Control usually requires a program counter PC, instruction storage IR, instruction decoder ID, timing and control circuits, as well as pulse sources, interrupts, etc. to be completed together. The controller consists of: instruction register, instruction decoder, programmable logic array for timing and control circuit, program counter, flags register, stack and stack pointer, storage group, etc. The main function of the controller is that the arithmetic unit can only perform calculations, while the controller is used to control the operation of the entire CPU. Instruction controller: Instruction controller is a very important part of the controller, which needs to complete operations such as fetching and analyzing instructions, and then hand them over to the execution unit ALU or FPU for execution, while also forming the address of the next instruction.

Timing controller: The function of a timing controller is to provide control signals for each instruction in chronological order. The timing controller includes a clock generator and a frequency doubling definition unit, where the clock generator emits a very stable pulse signal from a quartz crystal oscillator, which is the main frequency of the CPU; And the frequency doubling definition unit defines how many times the CPU main frequency is the bus frequency of the memory frequency. Bus controller: The bus controller is mainly used to control the internal and external buses of the CPU, including address bus, data bus, control bus, and so on.

PLC内的I/O模板，除-般的DI/DO、AD/DA模板外，还发展了系列特殊功能的I/O模板，这为PLC用于各行各业打开了出路,如盱条形码识别的ASCII/BASIC模板，于反馈控制的PID模板，紆运行控制、机械加工的高速计数模板、单轴位置控制模板、双轴位置控制模板、凸轮定位器模板、射频识别接口模板等，这在以后还会有很大发展。另外在输入、输出的相关元件、强干扰场合的输入、输出电隔离、地隔离等方面也会更加完善。
