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 anAC 900F controller. As there are only minor differences in appearance between theCPU 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 模組是AC 900F 控制器的核心元件。由於 CPU 模組型別在外觀上只有細微差異，因此當前包含 PM 904F 的圖紙和照片文件還適用於其他 CPU 模組型別.

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”.

本手冊中使用的術語"控制器"相當於FREELANCE工程中的"流程站"一詞或"AC 900F"的精確型別名稱。

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

除非描述特殊特診和特殊模組型別的功能，全篇文件使用PM、CI、CM、TA、TU等等對通常（模組）型別進行命名。

Depending on the application and requirements, the controller can becomplemented by additional modules. These modules are fieldbus communicationinterfaces and I/O modules

根據應用和需求，控制器可以輔以附加模組。這些（附加）模組是現場匯流排通訊介面和IO模組。

The AC 900F comprises the following components:

TD顯示單元（可選件）

• up to ten S700 I/O modules with I/O terminal blocks
• 帶有終端塊至多10個的S700 I/O模板
• max. four fieldbus communication interfaces
• 最多四個現場匯流排通訊介面

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

控制器可用於單個或冗餘配置。它支援使用PROFIBUS和其他現場匯流排協議的遠端 I/Os、變送器、執行器、驅動器和其他裝置。ABB 為標準和危險領域的應用提供廣泛的不同裝置和網路元件。

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

在本版本中，AC 900F 控制器支援以下現場匯流排技術：

• 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 usedeither as “direct” I/O or as remote I/O. For more detailed information on assemblyand installation of I/O modules, please refer to Mounting and InstallationInstructions, I/O Modules for AC 700F / AC 900F.

根據訊號型別和數量的不同，輸入輸出模板要麼作為本地IO，要麼作為遠端IO。有關 I/O 模組組裝和安裝的詳細資訊，請參閱安裝和安裝說明、AC 700F / AC 900F 的 I/O 模組。

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

與AC 700F和AC 800F類似，AC 900F的硬體配置基於硬體功能塊原理。

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

AC900F控制器為整合符合現場匯流排的元件——像遠端IO、現場裝置和網路元件——而設計。ABB為標準和危險區域應用提供裝置。
