ABB模块 3HNA015149-001

主要支持的硬件有： 

（1）电源（PS） 电源模块提供了机架和CPU内部的供电电源，置于1号机架的位置。 

（2）中央处理器（CPU） CPU存储并处理用户程序，为模块分配参数，通过嵌入的MPI总线处理编程设备和PC、模块、其它站点之间的通讯，并可以为进行DP主站或从站操作装配一个集成的DP接口。置于2号机架。 

（3）接口模块（IM） 接口模块将各个机架连接在一起。不同型号的接口模块可支持机架扩展或PROFIBUS DP连接。置于3号机架，没有接口模块时，机架位置为空。 

（4）信号模块（SM） 通常称为I/O（输入/输出）模块。测量输入信号并控制输出设备。信号模块可用于数字信号和模拟信号，还可用于进行连接，如传感器和启动器的连接。 

（5）功能模块（FM） 用于进行复杂的、重要的但独立于CPU的过程，如：计算、位置控制和闭环控制。 

（6）通讯处理器（CP） 模块化的通讯处理器通过连接各个SIMATIC站点

The main supported hardware is:

(1) Power Supply (PS) The power module provides power supplies for the rack and cpus and is installed in rack 1.

(2) Central Processing Unit (CPU) The CPU stores and processes user programs, assigns parameters to modules, handles communication between programming devices and PCS, modules, and other sites through an embedded MPI bus, and can be equipped with an integrated DP interface for DP master or slave station operations. Placed in rack 2.

(3) Interface Module (IM) The interface module connects racks together. Different models of interface modules can support rack extension or PROFIBUS DP connection. If no interface module is installed in rack 3, the rack is empty.

(4) The signal module (SM) is usually called the I/O (input/output) module. Measure input signals and control output devices. The signal module can be used for digital and analog signals, and can also be used to make connections, such as the connection of sensors and initiators.

(5) Function modules (FM) are used to carry out complex, important but CPU-independent processes such as calculation, position control and closed-loop control.

(6) Communication Processor (CP) Modular communication processor through the connection of various SIMATIC sites
