概述

1.1 AC 900F Controller

1.1 AC 900F控制器

     The PM 904F, PM 902F or PM 901F CPU module is the core component of an  AC 900F controller. As there are only minor differences in appearance between the CPU module types, the drawings and photos of the PM 904F included in the present
document also apply to the other CPU module types.

    PM 904F、PM 902F 或 PM 901F CPU 模块是AC 900F 控制器的核心组件。由于 CPU 模块类型在外观上只有细微差异，因此当前包含 PM 904F 的图纸和照片文档还适用于其他 CPU 模块类型.

    The term “controller” used in this manual is equivalent to the term “process station” in Freelance Engineering or to the precise type designation “AC 900F”.

    本手册中使用的术语'控制器'相当于FREELANCE工程中的'流程站'一词或'AC 900F'的精确类型名称。

      Unless a description refers to special features and functions of a specific module type variant, the general type designations PM, CI, CM, TA, TU etc. are used throughout this document.

      除非描述特殊特诊和特殊模块类型的功能，全篇文档使用PM、CI、CM、TA、TU等等对通常（模块）类型进行命名。

      Depending on the application and requirements, the controller can be complemented by additional modules. These modules are fieldbus communication interfaces and I/O modules

      根据应用和需求，控制器可以辅以附加模块。这些（附加）模块是现场总线通讯接口和IO模块。

       The AC 900F comprises the following components:

       AC900F控制器包含以下组件：

• PM CPU module with
• PM CPU模板包含

        –PM 904F: four slots, four Ethernet interfaces 

        PM 904F：四个插槽，4各以太网接口

       – PM 902F: two slots, four Ethernet interfaces

       PM 902F：两个插槽，4个以太网接口

      –  PM 901F: two slots, three Ethernet interfaces

      PM 901F:两个插槽，3个以太网接口

       –  one diagnostic interface

      一个诊断镊口

       –two serial interfaces

       两个串口

      –TD display unit (optional)

      TD显示单元（可选件）

• up to ten S700 I/O modules with I/O terminal blocks
• 带有终端块至多10个的S700 I/O模板
• max. four fieldbus communication interfaces
• 最多四个现场总线通讯接口

       The controller can be used in single or redundant configuration. It supports remote I/Os, transmitters, actuators, drives, and other devices using PROFIBUS and other fieldbus protocols. ABB offers a wide range of different devices and network components for applications in standard and hazardous areas.

       控制器可用于单个或冗余配置。它支持使用PROFIBUS和其他现场总线协议的远程 I/Os、变送器、执行器、驱动器和其他设备。ABB 为标准和危险领域的应用提供广泛的不同设备和网络组件。

      In the present version, the AC 900F controller supports the following fieldbus technologies:

     在本版本中，AC 900F 控制器支持以下现场总线技术：

• PROFIBUS-DP V0/V1
• Modbus RTU (serial) and Modbus TCP
• Telecontrol protocol (serial) and Telecontrol TCP
• ABB CAN Bus protocol

      Depending on type and number of process signals, input/output modules are used either as “direct” I/O or as remote I/O. For more detailed information on assembly and installation of I/O modules, please refer to Mounting and Installation Instructions, I/O Modules for AC 700F / AC 900F.

      根据信号类型和数量的不同，输入输出模板要么作为本地IO，要么作为远程IO。有关 I/O 模块组装和安装的详细信息，请参阅安装和安装说明、AC 700F / AC 900F 的 I/O 模块。

       Similar to the AC 700F and AC 800F, the hardware configuration of the AC 900F is based on the hardware function block principle

        与AC 700F和AC 800F类似，AC 900F的硬件配置基于硬件功能块原理。

       The AC 900F controller is designed for the combination with fieldbus-compliant components like remote I/O, field devices and network components. ABB offers equipment for applications in standard and hazardous areas

      AC900F控制器为整合符合现场总线的组件——像远程IO、现场设备和网络组件——而设计。ABB为标准和危险区域应用提供设备。
