　　CPU模块，全称中央处理器模块，是一种集成了CPU芯片和相关电路的组件。它是计算机系统中的核心部件，负责执行各种指令和进行数据处理。具体来说，CPU模块主要包括以下几个部分和功能：

　　控制单元：是整个CPU的指挥控制中心，负责协调整个电脑有序工作。它根据用户预先编好的程序，依次从存储器中取出各条指令，放在指令寄存器中，通过指令译码确定应该进行什么操作，然后通过操作控制器按确定的时序，向相应的部件发出微操作控制信号。

　　运算单元：是运算器的核心，可以执行算术运算(包括加减乘数等基本运算及其附加运算)和逻辑运算(包括移位、逻辑测试或两个值比较)。

　　存储单元：包括CPU片内缓存和寄存器组，是CPU中暂时存放数据的地方，里面保存着那些等待处理的数据或已经处理过的数据。CPU访问寄存器所用的时间要比访问内存的时间短，因此采用寄存器可以减少CPU访问内存的次数，从而提高CPU的工作速度。

　　The IC693CPU340RR is a single-slot CPU340 module with 32 KB of user memory and 10K registers. It has one CPU backboard and four expansion backboards for each system.

　　The IC693CPU340RR has a power supply that requires a +5 VDC power supply to provide a 350 mA load. It uses a processor 80188 with a processing speed of 10 megahertz. The operating temperature of IC693CPU340 is

　　0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit). Typically, the IC693CPU340RR has a scan rate of 0.3 milliseconds per 1K logic (Boolean contacts), and the firmware offers 9.0 as the highest user program memory.

　　240K bytes. The exact size of the current user program memory depends on the number designed for the word memory type of %R, %AI, and %AQ. It also has 512 discrete input and discrete output points. CPU

　　The 340 has 1280 bits of discrete global memory -%G

　　CPU module, the full name of the central processor module, is a component that integrates a CPU chip and related circuits. It is the core component in the computer system, responsible for executing various instructions and data processing. Specifically, the CPU module mainly includes the following parts and functions:

　　Control unit: is the command and control center of the entire CPU, responsible for coordinating the orderly work of the entire computer. According to the user's pre-programmed program, it takes out each instruction from the memory in turn, puts it in the instruction register, determines what operation should be carried out through the instruction decoding, and then sends a microoperation control signal to the corresponding component according to the determined time sequence through the operation controller.

　　Arithmetic unit: The core of the arithmetic unit, which can perform arithmetic operations (including basic operations such as addition and subtraction multipliers and their additional operations) and logical operations (including shifts, logic tests, or comparisons between two values).

　　Storage unit: including CPU on-chip cache and register group, is a temporary storage of data in the CPU, which stores the data waiting to be processed or has been processed. The time used by the CPU to access the register is shorter than the time used to access the memory, so the use of registers can reduce the number of times the CPU accesses the memory, thereby improving the CPU speed.
