Allen-Bradley 1756-L1 是属于 ControlLogix 产品系列的可编程自动化控制器 （PAC） 处理器模块。该处理器属于 ControlLogix 的早期版本之一，即 Logix 5550 类别。

该模块具有集成的 RS232 通信端口和 64KB 用户存储器。它还具有诊断前面板，可通过嵌入式 LED 灯报告模块的状态。随集成随机存取存储器 （RAM） 的备用电池提供，但是，该处理器未安装非易失性存储器。要为此控制器安装非易失性存储器，适当的存储器模块是唯一兼容的模块，1756-M1、1756-M2 和 1756-M3 是唯一兼容的模块。请勿使用其他内存模块，因为这将导致模块故障。

此模块可安装到任何 ControlLogix 机箱，例如 1756-A4、1756-A7、1756-A10、1756-A13 和 1756-A17。它占用机箱的单个插槽，模块电源由背板提供，背板由 ControlLogix 电源供电。

该控制器能够控制中等规模的过程。它支持 IEC-61131-2 定义的编程语言标准，例如梯形图、功能块、顺序功能图、语句列表编程语言。

集成的 RS232 为编程设备、人机界面 （HMI）、监控和数据采集 （SCADA） 以及其他可视化和控制系统提供接口。它还支持使用 ControlLogix I/O、Flex I/O 和 POINT I/O 模块进行独立和分布式 I/O 分配。

通信设置通过定义通信驱动程序的 RSLinx Classic 或 Enterprise Edition 定义。

【英文介绍】

The Allen-Bradley 1756-L1 is a ControlLogix 5550 controller. It can support up to 250 connections and weighs 0.28 kg or 10.0 oz. This particular controller has 64 KB of user memory. The 1756-L1 can be installed directly into any available slot in the chassis, and multiple controllers can be installed in any other slot within the same chassis. These controllers belong to the same chassis and can communicate with each other across the backplane or operate independently. The 1756-L1 is capable of communicating across DeviceNet, RS-232-C (DF1/DH-485 protocol), ControlNet, DH+, and EtherNet/IP networks. Note that it has no non-volatile memory.

The 1756-L1 has a peak backplane current of 0.65 amps at 5 V DC and 0.02 amps at 24 V DC. It also has an average power consumption of 3.3 watts and an average heat dissipation of 11.3 BTU/ hour. The 1756-L1 has a storage temperature of -40 to 85 degrees Celsius, while its operating temperature range is 0 to 60 degrees Celsius. It also has a non-condensing relative humidity of 5% to 95%. The 1756-L1 has a storage shock that peaks at 50 G and lasts 11 milliseconds, while its operating shock peaks at 30 G and lasts 11 milliseconds. It also has a vibration of 10 to 500 Hz and a maximum peak acceleration of 2.0 G. If the 1756-L1 has a battery that needs to be replaced, only the 1756-BA1, or 0.59g lithium battery, can be used. Programming cables compatible with 1756-L1 are Class 3 serial cables 1756-CP3 and 1747-CP3.

The Allen-Bradley 1756-L1 is a Programmable Automation controller (PAC) processor module belonging to the ControlLogix product family. This processor belongs to one of the earlier versions of ControlLogix, the Logix 5550 category.

The module has an integrated RS232 communication port and 64KB user memory. It also has a diagnostic front panel that reports the status of the module via embedded LED lights. It is supplied with a backup battery with integrated random access memory (RAM), however, the processor does not have non-volatile memory installed. To install a non-volatile memory for this controller, the appropriate memory module is the only compatible module, 1756-M1, 1756-M2, and 1756-M3 are the only compatible modules. Do not use other memory modules, as this will cause module failure.

This module can be installed into any ControlLogix chassis, such as 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17. It occupies a single slot in the chassis, and the module power is provided by the backplane, which is powered by the ControlLogix power supply.

The controller is capable of controlling medium-scale processes. It supports programming language standards defined by IEC-61131-2, such as ladder diagrams, function blocks, sequential function diagrams, and statement list programming languages.

The integrated RS232 provides interfaces for programming devices, human machine interfaces (HMI), supervisory control and data acquisition (SCADA), and other visualization and control systems. It also supports independent and distributed I/O allocation using ControlLogix I/O, Flex I/O, and POINT I/O modules.

Communication Settings are defined through RSLinx Classic or Enterprise Edition definitions that define communication drivers.
