VMIVME-4150 CPU运算和操控中心

1.CPU运算和操控中心
起“心脏”作用。
纵:当从编程器输入的程序存入到用户程序存储器中，然后CPU依据体系所赋予的功用(体系程序存储器的解说编译程序)，把用户程序翻译成PLC内部所认可的用户编译程序。
横:输入状况和输入信息从输入接口输进，CPU将之存入工作数据存储器中或输入映象寄存器。然后由CPU把数据和程序有机地结合在一起。把结果存入输出映象寄存器或工作数据存储器中，然后输出到输出接口、操控外部驱动器。
组成:CPU由操控器、运算器和寄存器组成。这些电路集成在一个芯片上。CPU通过地址总线、数据总线与I/0接口电路相连接。
特点:
多达12路完全阻隔的模拟输出
12位分辨率
电压输出范围可选择为2.5、5或10 V在整个10V范围内，电压输出的负载能力为10mA供给4至20mA电流环路输出电压输出精度为0.05%，电流环路输出精度为0.08%4通道、8通道和12通道装备光学数据耦合供给完全的电流阻隔静态回读数据寄存器简化了程序操控

1.CPU computing and control center

Act as the "heart".

When the program input from the programmer is stored into the user program memory, then the CPU translates the user program into the user compiler approved by the PLC according to the function given by the system (the explanation of the system program memory).

Horizontal: Input status and input information are input from the input interface, which the CPU stores in the working data memory or input image register. The data and the program are then organically combined by the CPU. The result is stored in the output image register or working data memory, and then output to the output interface to control the external drive.

Composition: The CPU is composed of a controller, an arithmetic and a register. These circuits are integrated on a single chip. The CPU is connected to the I/0 interface circuit through the address bus and data bus.
