1756-L83E 控制器  嵌入式以太网通信端口

【产品详情】

该控制器还设计有嵌入式以太网通信端口，支持自动协商，支持 10/100/100 Mbps 传输速率。只有线性拓扑可以通过这个嵌入式端口实现，但是，这个控制器模块支持添加通信模块，如EtherNet/IP、ControlNet、DeviceNet、Data Highway Plus、远程I/O、SynchLink和第三方过程和设备网络，以实现更复杂的通信拓扑。

BOOTP-DHCP实用程序用于配置此模块的IP地址。对于标准应用，此控制器支持配置静态 IP 地址，但对于高级安全要求，也可以配置动态 IP 参数。使用动态参数时，地址会在每次电源循环或由网络提供商触发时更改。此设置非常适合关键应用程序，以防止对控制和操作数据进行不必要的访问。

此控制器支持冗余架构，可提高此控制器的可用性。它使系统能够在主控制器发生故障时自动切换到辅助处理器。它还能够使用本机 ControlLogix 模块或 I/O 系统（如 Flex I/O 或 POINT I/O）实现远程 I/O 系统。它还可以通过中间指令与其他 Allen-Bradley 可编程逻辑控制器 （PLC） 进行通信，例如 PLC 5、SLC 500、MicroLogix 和 CompactLogix 控制器。

Allen-Bradley 1756-L83E 是一款以 EtherNet/IP 通信为中心的 ControlLogix 5580 控制器。它支持 32 个任务，其中多达 1000 个程序/任务，包括实现所有事件触发器的事件任务。该控制器具有 10 MB 的数据和逻辑可用用户存储器以及可选的非易失性存储器。它随附一个 2 GB 安全数字 （SD） 卡，即 1784-SD2，该卡已预装在控制器中。该控制器还具有一个不可拆卸的储能模块，该模块已嵌入到控制器中。1756-L83E 控制器提供 2 个通信端口、一个 B 型 USB 端口和一个嵌入式以太网端口。

建议您仅使用罗克韦尔自动化 SD 卡，因为这些卡已经过测试，可与 1756-L83E 等控制器配合使用，并可承受控制器可能承受的极端温度。当您使用其他 SD 卡时，您可能会丢失或损坏数据。请务必保留 SD 卡的安装状态，因为如果出现故障，诊断数据将保存在此处。

【英文介绍】

The controller is also designed with an embedded Ethernet communication port, supports auto-negotiation, and supports 10/100/100 Mbps transfer rates. Only linear topologies can be implemented through this embedded port, however, this controller module supports the addition of communication modules such as EtherNet/IP, ControlNet, DeviceNet, Data Highway Plus, remote I/O, SynchLink, and third-party process and device networks. To achieve more complex communication topologies.

The BOOTP-DHCP utility is used to configure the IP address of this module. This controller supports the configuration of static IP addresses for standard applications, but dynamic IP parameters can also be configured for advanced security requirements. When using dynamic parameters, the address changes with each power cycle or triggered by the network provider. This setting is ideal for critical applications to prevent unnecessary access to control and operational data.

This controller supports redundant architecture, which improves the availability of this controller. It enables the system to automatically switch to the auxiliary processor in the event of a primary controller failure. It is also capable of implementing remote I/O systems using native ControlLogix modules or I/O systems such as Flex I/O or POINT I/O. It can also communicate with other Allen-Bradley programmable logic controllers (PLCS), such as PLC 5, SLC 500, MicroLogix, and CompactLogix controllers, via intermediate instructions.

The Allen-Bradley 1756-L83E is a ControlLogix 5580 controller centered on EtherNet/IP communication. It supports 32 tasks with up to 1000 programs/tasks, including event tasks that implement all event triggers. The controller has 10 MB of data and logic available user memory and optional non-volatile memory. It comes with a 2 GB Secure digital (SD) card, the 1784-SD2, which is pre-installed in the controller. The controller also has a non-removable energy storage module, which is embedded in the controller. The 1756-L83E controller offers two communication ports, a Type B USB port, and an embedded Ethernet port.

It is recommended that you only use Rockwell Automation SD cards, as these have been tested to work with controllers such as the 1756-L83E and can withstand the extreme temperatures that a controller can withstand. When you use another SD card, you may lose or corrupt data. Be sure to leave the SD card in the installed state, as this is where the diagnostic data will be saved if something goes wrong.
