>>>>>型號:1756-L73  處理器模塊 可編程自動化控制器 

【功能描述】

Allen-Bradley 1756-L73 是一款 ControlLogix 處理器模塊，屬于 Logix 5570 產(chǎn)品類別。這是一款可編程自動化控制器 （PAC），兼容用于控制工廠或過程自動化應用中的大型應用。它支持單工配置和高可用性（冗余）控制器配置，以提高系統(tǒng)可用性。

1756-L73 能夠連接 128,000 個輸入和輸出信號以及 4000 個模擬輸入和輸出信號。它可以是實現(xiàn)本地 I/O 配置，其中 I/O 模塊安裝在安裝控制器的同一機箱中，也可以是分布式 I/O 拓撲，其中擴展 I/O 安裝在遠離處理器并通過擴展通信總線提供 I/O 的分布式 I/O 拓撲中。該控制器支持以太網(wǎng) I/P、DeviceNet、ControlNet、Synchlink 以及傳統(tǒng)通信協(xié)議，如 Data Highway Plus （DH+）、遠程 I/O （RIO） 和第三方協(xié)議。它也可以配置為與網(wǎng)關(guān)和協(xié)議轉(zhuǎn)換器通信。同樣，該控制器與任何 Allen-Bradley encompass 合作伙伴 ControlLogix 模塊兼容。

該控制器還具有集成運動功能，因為它支持 SERCOS 接口、模擬運動傳感器和通過以太網(wǎng) I/P 進行的運動控制。對該控制器進行編程時，適用的編程語言包括繼電器梯形圖、結(jié)構(gòu)化文本、功能塊圖和順序功能圖。

該控制器能夠處理 32 個控制器任務，每個任務有 100 個程序，而事件任務接受所有事件觸發(fā)器。該控制器配備 8MB 用戶內(nèi)存和 0.98 MB 的 I/O 內(nèi)存。它還配備了儲能技術(shù)，無需使用電池來保留易失性存儲器的內(nèi)容。

【英文介紹】

The Allen-Bradley 1756-L73 is a ControlLogix processor module in the Logix 5570 product category. It is a programmable automation controller (PAC) that is compatible for controlling large applications in factory or process automation applications. It supports simplex configuration and high availability (redundant) controller configuration to improve system availability.

The 1756-L73 is capable of connecting 128,000 input and output signals and 4,000 analog input and output signals. It can be either a local I/O configuration, where the I/O module is installed in the same chassis where the controller is installed, or a distributed I/O topology, where the extended I/O is installed in a distributed I/O topology away from the processor and provided through an extended communication bus. The controller supports Ethernet I/P, DeviceNet, ControlNet, Synchlink, and traditional communication protocols such as Data Highway Plus (DH+), Remote I/O (RIO), and third-party protocols. It can also be configured to communicate with gateways and protocol converters. Again, the controller is compatible with any Allen-Bradley encompass partner ControlLogix module.

The controller also has integrated motion capabilities as it supports SERCOS interfaces, analog motion sensors, and motion control over Ethernet I/P. When programming the controller, the applicable programming languages include relay ladder diagram, structured text, function block diagram and sequence function diagram.

The controller is capable of handling 32 controller tasks, each with 100 programs, while the event task accepts all event triggers. The controller comes with 8MB of user memory and 0.98MB of I/O memory. It is also equipped with energy storage technology that does not require the use of batteries to retain the contents of volatile memory.
