>>>>>型号:1756-L73 处理器模块 可编程自动化控制器
【功能描述】
Allen-Bradley 1756-L73 是一款 ControlLogix 处理器模块，属于 Logix 5570 产品类别。这是一款可编程自动化控制器 （PAC），兼容用于控制工厂或过程自动化应用中的大型应用。它支持单工配置和高可用性（冗余）控制器配置，以提高系统可用性。
1756-L73 能够连接 128,000 个输入和输出信号以及 4000 个模拟输入和输出信号。它可以是实现本地 I/O 配置，其中 I/O 模块安装在安装控制器的同一机箱中，也可以是分布式 I/O 拓扑，其中扩展 I/O 安装在远离处理器并通过扩展通信总线提供 I/O 的分布式 I/O 拓扑中。该控制器支持以太网 I/P、DeviceNet、ControlNet、Synchlink 以及传统通信协议，如 Data Highway Plus （DH+）、远程 I/O （RIO） 和第三方协议。它也可以配置为与网关和协议转换器通信。同样，该控制器与任何 Allen-Bradley encompass 合作伙伴 ControlLogix 模块兼容。
该控制器还具有集成运动功能，因为它支持 SERCOS 接口、模拟运动传感器和通过以太网 I/P 进行的运动控制。对该控制器进行编程时，适用的编程语言包括继电器梯形图、结构化文本、功能块图和顺序功能图。
该控制器能够处理 32 个控制器任务，每个任务有 100 个程序，而事件任务接受所有事件触发器。该控制器配备 8MB 用户内存和 0.98 MB 的 I/O 内存。它还配备了储能技术，无需使用电池来保留易失性存储器的内容。

【英文介绍】
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.
