CP451-10 Yokogawa横河 处理器模块是整个CPU的命今控制中心，由指令寄存器IRlnstruction Register)、指令解码器D(nstruction Decoder)、操作控制器0COperationcontroler)等组成，保持整个电脑的正常运行是很重要的。它根据用户预先编好的程序，依次以存储器中取出每条指令，放入指今客存器IR中，通过指令解码(分析)确定需要执行什么操作，然后通过操作控制器OC，按照确定的时间顺序，向相应的部件发出微操作控制信号。操作控制器OC主要包括节拍脉冲发生器、控制矩阵、时钟脉冲发生器、复位电路和断电电路控制逻辑运算器
是计算机的核心。您可以执行算术运算(包括基本运算，如加减乘数及其附加运算)和逻辑运算(包括移位、逻辑测试或两个值的比)。相对于控制单元来说，计算机接受控制单元的命今并执行动作，即算术单元所执行的一切操作都是由控制单元发出的控制信号来指挥的，因此它是执行部件，存储单元
这些包括芯片内缓存和寄存器库，它们是CPU中等待处理或已经处理的数据的临时存储。CPU访问存器的时间比访问内存的时间要少。寄存器的使用可以减少CPU访问内存的次数，从而提高CPU的工作速度，然而，由于芯片面积和集成度的限制，寄存器库的容量不能很大。寄存器组可分为特殊寄存器和一般存器。专用存器的功能是固定的，分别存放相应的数据，另一方面，通用寄存器是通用的，可以由程序员指定，通用寄存器的数量因微处理器而异121。

Yokogawa CP451-10 CPU processor module, a small control group consisting of function blocks and input/output will be described in the control chart, the CP451-10 CPU processor module simplifies engineering and maintenance by unifying process equipment control into a control chart. The CP451-10 CPU processor module monitors the entire plant or each process can also be specified as a control chart, rather than specifying individual process units or functions between devices.
CP451-10 CPU Processor module The following describes the characteristics of the control chart
Connecting I/0 and control blocks You can visualize data flow definitions by connecting a line between /0 and function blocks or between function blocks
1, Define the order of control block implementation You can determine the implementation priority or execution order in several functional blocks described in the control chart
2, Mixing of adjustment control and sequence control Adjustment control and sequence control can be mixed in the control chart. The control function can be flexibly configured according to process requirements
3, the free signal flow between the control charts belongs to the function block of different control charts can be connected to another control chart.
Yokogawa CP451-10 CPU Processor module:
Three connections are available between the CP451-10 1/0 module and the field device
CP451-10 CPU Processor Module Dedicated Signal cable connections, pressure terminal connections, and MIL cable connections CP451-10 For dedicated signal cable connections, dedicated signal cables are used to connect field devices via terminal or relay boards. The signal cable interface adapter is structurally integrated with the CP451-10/0 module to prevent the insertion of the wrong type of I/O module by selecting the option code for the /0 module and the signal cable respectively. As for pressure terminal connections, field devices can be connected directly to/modules.
Yokogawa (P451-10/0 module has two types of pressure terminals to choose from one is a single configuration type, the other is a dual configuration type. VO module can realize double redundancy on the terminal block
Customer-supplied MIL cables can be connected directly to the /0 module without the need for terminals. To prevent ML cables from disconnecting from the /0 module, cable connection covers (SCCC01 and SCCC02) can be used with MIL cables.
CP451-10 Yokogawa Yokogawa processor module
CP451-10 Yokogawa processor module is the current control center of the entire CPU, Consisting of instruction Register IRlnstruction Register, instruction Decoder D(nstruction Decoder), operation controller 0COperationcontroler, etc., it is important to keep the whole computer running properly. According to the user’s pre-programmed program, it takes out each instruction from the memory in turn, puts it into the current guest storage IR, determines what operation needs to be performed through instruction decoding (analysis), and then sends a microoperation control signal to the corresponding component by operating the controller OC in accordance with the determined time order. The operation controller OC mainly includes a beat pulse generator, control matrix, clock pulse generator, reset circuit and power off circuit control logic arithmetic
It’s the heart of the computer. You 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 ratios of two values). Compared with the control unit, the computer accepts the command of the control unit and performs the action, that is, all the operations performed by the arithmetic unit are commanded by the control signal issued by the control unit, so it is an executive part and a storage unit
These include on-chip caches and register libraries, which are temporary stores of data waiting to be processed or already processed in the CPU. The CPU spends less time accessing memory than it does accessing memory. The use of registers can reduce the number of times the CPU accesses the memory, thereby improving the CPU’s working speed, however, due to the limitations of chip area and integration, the capacity of the register library can not be very large. Register groups can be divided into special registers and general registers. The function of the special memory is fixed, respectively storing the corresponding data, on the other hand, the general register is general purpose, can be specified by the programmer, the number of general registers varies by the microprocessor 121.
