该控制器是现代 Logix 控制器平台的一部分，该平台被归类为可编程自动化控制器 （PAC）。该PAC产品系列非常适合大中型自动化要求，特别符合工厂和过程自动化行业的控制要求。

1756-L71主要具有2MB用户存储器和0.98MBI/O存储器。它还随附一张 1784-SD1 安全数字 （SD） 存储卡，相当于 1 GB 非易失性存储器，可通过更换为 2-SD1784 卡升级到 2GB。该控制器可以处理多达 128,000 个离散输入和输出信号以及 4000 个模拟输入和输出信号。

作为现代控制器，1756-L71不使用电池来保留随机存取存储器（RAM）或易失性存储器的内容，而是配备了目录号为756-ESMCAP或1756-ESMCAPK的储能模块。该储能模块是基于电容器的可拆卸类型。

对于工业通信，1756-L71 支持安装通信适配器。1756-L71支持的其他通信协议包括EtherNet/IP，ControlNet，DeviceNet，Data Highway Plus，Remote I / O，SynchLink，第三方进程和设备网络。

此控制器是基于机箱的控制器。这意味着必须安装特定的 ControlLogix 机箱才能安装模块。兼容的机箱包括 1756-A4、1756-A4K、1756-A7、1756-A7K、1756-A10、1756-A10K、1756-A13、1756-A13K、1756-A17、1756-A17 K。

【英文介绍】

The Allen-Bradley 1756-L71 is a ControlLogix programmable automation controller. It has 2 MB of user memory available storage and 0.98 MB of I/O memory. It also features an onboard 4-character alphanumeric display for easy monitoring of runtime and module information as well as controller diagnostics. It has an open housing and built-in one (1) 2.0 full speed USB ports. Available communication options include DeviceNet, ControlNet, EtherNet/IP, Remote I/O Data Highway Plus, third-party processes and networks, and SynchLink. It also comes with 1 GB of non-volatile memory, but you can upgrade it to 2 GB with the 2-SD1784. You are advised to leave the SD card in the controller. The 1756-L71 controller comes with three capacitive energy storage modules, two of which are removable. Its current consumption is 2 mA at 5.1 volts DC and 1 mA at 800.5 volts DC. The 1756-L71 controller also has a continuous isolation voltage of 30 volts, a maximum power consumption of 2.5 watts, and a heat dissipation of 8.5 BTU/ hour. Its maximum analog I/O, digital I/O and total I/O are 4,000, 128,000 and 128,000, respectively. It has an operating temperature range of 0 to 60 degrees Celsius and a storage temperature range of -40 to 85 degrees Celsius. The maximum ambient air temperature is 60 degrees Celsius, and the non-condensing relative humidity is 5% to 95%. The controller has 500G vibration at 2 to 10 Hz, 30G operating shock and 50G non-operating shock, dropping to 45G when SD card is installed. Other controllers may require the user to know the first PLC register, especially bytes and bits, in order to begin addressing program elements. With the 1756-L71, the user simply inserts the program element and selects the logical channel where the I/O physical connection is located. In other PLCS, users may find it necessary to move a register to another register to initiate conversion and processing to obtain analog data. The controller only requires the user to find the logical channel that physically terminates the I/O signal.

The controller is part of the modern Logix controller platform, which is classified as a Programmable Automation Controller (PAC). The PAC product family is well suited for medium to large scale automation requirements, particularly for the control requirements of the factory and process automation industry.

The 1756-L71 mainly has 2MB of user memory and 0.98MBI/O memory. It also comes with a 1784-SD1 secure digital (SD) memory card, equivalent to 1 GB of non-volatile memory, which can be upgraded to 2GB by replacing it with a 2-SD1784 card. The controller can process up to 128,000 discrete input and output signals and 4,000 analog input and output signals.

As a modern controller, the 1756-L71 does not use a battery to retain the contents of random access memory (RAM) or volatile memory, but is equipped with an energy storage module with the catalog number 756-ESMCAP or 1756-ESMCAPK. The energy storage module is based on a removable type of capacitor.

For industrial communications, the 1756-L71 supports the installation of a communication adapter. Other communication protocols supported by the 1756-L71 include EtherNet/IP, ControlNet, DeviceNet, Data Highway Plus, Remote I/O, SynchLink, third-party processes, and device networking.

This controller is a chassis based controller. This means that a specific ControlLogix case must be installed to install the module. Compatible chassis include 1756-A4, 1756-A4K, 1756-A7, 1756-A7K, 1756-A10, 1756-A10K, 1756-A13, 1756-A13K, 1756-A17, 1756-A17 K.
