CPU314产品概述
- 用于具有中等程序规模需求的应用
- 对二进制和浮点数运算具有较高的处理能力
CPU 运行需要 SIMATIC 微存储卡(MMC)
应用
CPU 314 用于对处理能力和响应速度有很高要求的场合。通过其工作存储器,该CPU也适用于中等规模的应用。
设计
CPU 314 安装有:
- 微处理器;
处理器对每条二进制指令的处理时间大约为 60 ns,每个浮点预算的时间为 0.59 µs。 - 扩展存储器;
与执行相关的程序段的 128 KB 高速 RAM(相当于约 42 K 指令)可以为用户程序提供足够的空间;
SIMATIC 微型存储卡(zui大 8 MB)作为程序的装载存储器,还允许将项目(包括符号和注释)存储在 CPU 中。 - 灵活的扩展能力;
多达 32 个模块,(4排结构) - MPI多点接口;
集成的 MPI 接口zui多可以同时建立与 S7-300/400 或编程设备、PC、OP 的 12 条连接。在这些连接中,始终为编程器和 OP 分别预留一个连接。通过“全局数据通讯”,MPI可以用来建立zui多16个CPU组成的简单网络。 - -----------------------------------------------------------------------

订货号:6ES7314-1AG14-0AB0 产品说明:SIMATIC S7-300,CPU 314 *处理器 mit MPI, integr. 电源 DC 24V, 工作存储器 128 KByte, 需要微型存储卡
----------------------------------------------------------------------------------------------
功能
- 口令保护;
用户程序使用密码保护,可防止非法访问。 - 诊断缓冲;
诊断缓冲区中可存储zui后 500 个错误和中断事件,其中的 100 个事件可以*保留。 - 免维护的数据后备;
如果电源中断,CPU 将所有数据(多达 64 KB)自动写到 SIMATIC 微型存储卡(MMC 卡)上,从而使数据可以在电压恢复后再次使用,且不会发生改变。
可参数化的特性
可以使用 STEP 7 对 S7 的组态、属性以及CPU的响应进行参数设置:
- MPI多点接口;
定义站地址 - 重启动/循环时间特性;
zui大循环时间以及负载限制,以及自检测功能 - 保持范围;
定义具有保持功能的存储位、计数器、定时器和数据块的数量 - 时钟存储器;
设定地址 - 防护等级;
定义程序和数据的访问权限 - 系统诊断;
定义诊断报警的处理和范围 - 看门狗中断;
周期设定 - 时钟中断;
设定起始日期、起始时间和间隔周期
-----------------------------------------------------------------------
显示功能与信息功能
- 状态和故障指示;
发光二极管显示,例如,硬件、编程、定时器或I/O出错以及运行模式,如RUN、STOP、Startup。 - 测试功能;
可使用编程器显示程序执行过程中的信号状态,可以不通过用户程序而修改过程变量,以及输出堆栈内容。 - 信息功能;
您可以使用编程器以纯文本的形式获取 CPU 存储容量和操作模式、主存储器和装载存储器的当前利用率以及当前循环时间和诊断缓冲区内容的相关信息。
集成的通讯功能
- PG/OP 通讯
- 全局数据通讯
- S7 基本通讯
- S7 通讯(只是服务器)
-----------------------------------------------------------------------------------
系统功能
CPU 具有广泛的系统功能特性,诸如:诊断、参数赋值、报警、定时和测量等。
