過程站
1.1Overview
概述
A scalable Freelance system essentially consists of the process and operatorstations. You can perform the necessary configuration and commissioning tasksfrom your PC using the Freelance Engineering software. Diagnoses are performedin graphic interfaces.
一個可伸縮的freelance系統由過程站和操作員站組成。你可以使用電腦上的freelance 工程軟體執行配置和除錯任務。圖形介面執行診斷。
Among the functions supported by Freelance Engineering are the following:
freelance工程下列功能：
- Read and enhance configuration data from new field devices.從新的現場裝置中讀取和提高配置資料。
- Configure devices using the parameter setting dialogs and pre-defined I/O structures.使用引數設定對話方塊和預定義的I/O結構配置裝置。
- Display bus cycle times and diagnostic data of devices.顯示匯流排週期和裝置診斷資料。
- Search the buses for nodes with unknown device addresses.在匯流排中搜索具有未知裝置地址的節點。
- Exclude individual devices from cyclic communication.將單個裝置排除在迴圈通訊之外。
- Integrate new devices without the need to re-initialize the bus line.無需初始化匯流排線路，整合新的裝置。
To configure your automation task, first create the required resources and programsin the project tree using editors conforming to IEC 61131-3. In the next step, theseconfigured applications are allocated to the actually required hardware in thehardware editor and then loaded online into the process stations.
為了配置自動化任務，首先使用符合IEC 61131-3的編輯器在專案樹中建立資源和程式。接下來，這些配置分配給硬體編輯器中實際需要的硬體，然後線上載入到過程站。
In order to facilitate the visualization of your process, powerful software packagessuch as Freelance Operations are available for operation.
為了促進過程視覺化，諸如Freelance OPerations的強大的軟體包可供操作。
A Freelance system supports different types of process stations (controllers) whichcan be combined as required. Currently, the controller types AC 900F, AC 800F andAC 700F are available.
一個freelance系統支援不同的過程站，可根據需要組合。目前控制器有AC 900F、AC 800F、AC 700F可供選擇。
The Ethernet system bus links the individual stations with each other. This bustransmits the data between the process stations, the operator stations and theengineering station. Communication within the process station, i.e. datatransmission between the CPU module and the connected modules, is realized viathe internal station bus.
乙太網系統連線各個站點。匯流排在過程站、操作員站、工程師站之間傳輸資料。站內通訊，也即CPU模板和連結模板之間的資料傳輸，是通過站內匯流排實現的。
Communication between the AC 900F process stations and operator/gatewaystations as well as lateral communication between the AC 900F process stations canoptionally be performed via a redundant Control Net.
AC 900F過程站和操作員/閘道器站之間的通訊，以及AC 900F過程站之間的橫向通訊，都可以可選地通過冗餘控制網執行。
Control Net redundancy is supported by the following Freelance process stations:
下列Freelance 過程站支援控制網路冗餘：
- AC 900F
- AC 900F redundant
- AC 900F Lite
- AC 900F Lite redundant
- AC 900F Plus
- AC 900F Plus redundant
The following sections provide an overview of the currently available processstations. See the corresponding Mounting and Installation Instructions for moredetailed information. Older hardware and process stations of previous systemreleases are also supported, but are not described in this manual. For information inthis matter, see the manuals of the corresponding system releases.
以下部分概述了當前可用過程站。更多細節參見相應的安裝說明。也支援以前系統釋出的舊硬體和過程站，但本手冊不支援。此事的更多資訊，參閱相應系統釋出手冊。
1.1.1 AC 900F process station
AC 900F過程站
The AC 900F process station is available in two variants, namely Standard, Liteand Plus version.
AC 900F過程站有兩個可用版本，命名為標準版，低配版和增強版。
The AC 900F Lite process station is designed for smaller lines:
AC 900F低配版過程站設計用於小型產線：
- there are only three instead of four Ethernet interfaces available,使用3個網口替代4個可用網口。
- the available memory capacity and the controller performance are lower than with the Standard version.可用記憶體容量和控制其效能低於標準版。
- it is recommended not to configure more than 400 I / O signals.建議配置的IO點數不要超過400個。
The AC 900F Plus process station is designed for larger lines:
AC 900F增強版過程站設計用大大型產線：
- four slots for fieldbus communication interfaces,四個現場匯流排通訊介面插槽。
- the available memory capacity and the controller performance are higher than with the Standard version.可用記憶體容量和控制器效能高於標準版本。
Details and technical data of the variants are included in the Mounting andInstallation Instructions, AC 900F Controller.
各種細節和技術資料包含在《Mounting andInstallation Instructions, AC 900F Controller.》（這個資料就是前面的練習連續學習翻譯的那本）
The descriptions in the present document generally apply to all variants; differencesare explicitly specified, where applicable.
本檔案的說明一般適用於所有變型;差異在適用時明確指定。

Depending on the type and quantity of process signals, up to ten plug-in typeinput/output modules can be directly connected. Additionally, two (PM 901F /PM 902F) or four (PM 904F) extensive PROFIBUS lines can be connected viatwo/four PROFIBUS modules. The CAN module (max. one per controller) allowsconnection of a maximum of 5 rack I/O units and thus the connection of 45 I/Omodules as used in the rack-based Freelance process stations.
依據過程訊號的型別和數量，最多可以直接連線10個輸入/輸出模板。另外，通過2個/4個PROFIBUS模板，可以連線2個（PM 901F/PM 902F）或者4個（PM 904F)擴充套件PROFIBUS線路。CAN模板（每個控制器最多1個）允許最多5個I/O機架IO單元，因此可以連線45個基於機架的freelance過程站使用的I/O模組。
The following directly connected I/O modules are available for an AC 900F (nonredundant controller only): AC 900F（僅限非冗餘控制器）允許直連下列I/O模板： AI 723F Analog input module: 16 AI/DI | AI 723F 模擬量輸入模板：16點 AI/DI AI 731F Analog input module: 8 AI/DI | AI 731F 模擬量輸入模板：8點 AI/DI AO 723F Analog output module：16 AO | AO 723F 模擬量輸出模板 16點 AO AX 721F Analog input/output module: 4 AI/DI, 4 AO | AX 721F 模擬量輸入輸出模板：4點 AI/DI,4點 AO AX 722F Analog input/output module: 8 AI/DI, 8 AO | AX 722F 模擬量輸入輸出模板：8點AI/DI，8點AO DA 701F Digital/analog input/output module: 16 DI, 8 DI/DO, 4 AI/DI, 2 AO | DA 701F 數字量/模擬量輸入/輸出模板：16點DI，8點DI/DO，4點AI/DI，2點AO DC 732F Digital input/output module: 16 DI, 16 DI/DO | DC 732F 數字量輸入/輸出模板：16點DI，16點DI/DO DI 724F Digital input module: 32 DI | DI 724F 數字量輸入模板：32點DI DX 722F Digital input/output module: 8 DI, 8 DO (relay contacts) | DX 722F 數字量輸入/輸出模板：8點DI，8點DO（繼電器接觸） DX 731F Digital input/output module: 8 DI, 4DO (relay contacts) | DX 731F 數字量輸入/輸出模板：8點DI，4點DO（繼電器接觸） The following fieldbus communication interfaces are available: CI 910F CAN module for Rack-I/O | CI 910F IO機架所用CAN 模板 CI 930F PROFIBUS module, suitable for redundant configurations | CI 930F PROFIBUS 模板，適用冗餘配置 CM 772F PROFIBUS module (only usable with PM 902F) | CM 772F PROFIBUS 模板（僅配合PM 902F使用） CI 773F PROFIBUS module | CI 773F PROFIBUS 模板 The AC 900F internal interfaces support additional serial Ethernet fieldbusprotocols such as Modbus, Send and Receive Function Blocks and Telecontrol LinkUp. Fieldbus-compatible components such as remote I/O, field devices and networkcomponents can be connected to the AC 900F process station and configured usingFreelance Engineering. ABB offers equipment for applications covering standardand hazardous areas. AC 900F內部介面支援額外的串列埠乙太網現場匯流排協議，比如Modbus，傳送和接收功能塊和遙控連線。相容現場匯流排的元件，比如遠端IO，現場裝置和網路元件能夠連線到AC 900F過程站，使用Freelance工程進行配置。ABB提供好改標準到危險區域的裝置應用。 An AC 900F controller without direct I/O modules can be run in redundantconfiguration. For this purpose, two process stations of identical design areconnected by means of a redundancy link. The ETH2 Ethernet interface must be used for the redundancy link; see the Mounting and Installation Instructions, AC 900F Controller, Commissioning for details. 不帶直接IO模板的AC 900F控制器可以在冗餘配置下執行。為此目的，兩個相同設計的過程站通過冗餘相連。ETH2網路介面必須用於冗餘連線；細節參見《the Mounting and Installation Instructions, AC 900F Controller》一文，除錯章節。（我前段時間學習翻譯的那個文件）| In a redundant AC 900F controller, the CI 930F and CI 773F PROFIBUS modules respectively the CI 910F CAN module can be used. The CM 772F PROFIBUS module does not support the redundancy mode. 在冗餘AC 900F控制器中，CI 930F和CI 773F PROFIBUS模板分別使用CI 910F CAN模組。 |
