Allen-Bradley（罗克韦尔自动化的一个部门）的1715-AENTR 是一款冗余 I/O 系统的以太网/IP 适配器通信模块。这个模块支持设备级环网（DLR）或星形拓扑，并且具有自动感应 10/100BASE-TX 以太网端口 。1715-AENTR 模块充当所有进出冗余 I/O 模块的以太网 I/P 消息的“代理”模块，是专门为 ControlLogix 系列可编程自动化控制器（PAC）设计的。通过实施冗余 I/O 系统和冗余通信网络，可以延长流程的正常运行时间并降低不必要的系统停机风险 。

1715-AENTR 模块在单工模式下使用时，可以配置冗余以太网网络。如果使用双工模式，两个适配器模块中的一个出现故障不会影响整个通信网络，从而提高系统可用性 。该模块非常灵活，支持各种配置，包括双工端接适配器、双工输入模块和双工输出模块，且不需要复杂的编程或交叉布线 I/O 。

此外，1715-AENTR 模块还具备高级诊断功能，包括设备智能等，通过内部诊断实现状态监控，并对可能引起问题的当前异常（开路/短路、阈值或变化率）提供特殊警报 。

对于 1734-AENTR 模块的配置，它具有两个网口、三个拨码开关和五个状态指示灯。当模块需要设置 IP 地址时，可以通过拨码开关设置，例如，设置为 192.168.1.100 时，将拨码设置为 100，然后使用 BootP 软件进行 IP 地址设置 。如果需要恢复模块到出厂设置，可以在通电的情况下将拨码设为 888，然后断电再上电 。

在配置 1734-AENTR 模块时，可以通过 Studio 5000 软件进行设置。例如，新建一个项目后，在 Ethernet 网络中添加 1734-AENTR 模块，并输入模块名称和 IP 地址，然后在“Elcetronic Keying”中选择“Compatible Module”并设置“Chassis Size” 。

请注意，虽然 1715-AENTR 和 1734-AENTR 模块在名称上相似，但它们属于不同的产品系列，具有不同的功能和应用场景。1715-AENTR 是冗余 I/O 系统的以太网/IP 适配器模块，而 1734-AENTR 是远程 I/O 模块，通常用于 ControlLogix 系统的远程通信和数据采集 。

The 1715-AENTR from Allen-Bradley (a division of Rockwell Automation) is an Ethernet /IP adapter communication module for redundant I/O systems. This module supports device level ring network (DLR) or star topology and has an automatic sensing 10/100BASE-TX Ethernet port. The 1715-AENTR module acts as a "proxy" module for all Ethernet I/P messages to and from redundant I/O modules and is designed specifically for the ControlLogix family of programmable Automation controllers (PACs). By implementing redundant I/O systems and redundant communication networks, you can extend process uptime and reduce the risk of unnecessary system downtime.

The 1715-AENTR module can be configured with a redundant Ethernet network when used in simplex mode. If duplex mode is used, the failure of one of the two adapter modules does not affect the entire communication network, thus improving system availability. The module is flexible and supports a variety of configurations, including duplex terminating adapters, duplex input modules, and duplex output modules, without requiring complex programming or cross-cabling I/O.

In addition, the 1715-AENTR module has advanced diagnostic capabilities, including device intelligence, condition monitoring through internal diagnostics and special alerts for current anomalies (open/short circuit, threshold or rate of change) that could cause problems.

For the configuration of the 1734-AENTR module, it has two network ports, three dip switches, and five status indicators. If the module needs to set an IP address, you can set it using the DIP switch. For example, if 192.168.1.100 is set, set the DIP switch to 100, and then use the BootP software to set the IP address. If you need to restore the module to factory Settings, you can set the DIP switch to 888 when the power is on, and then power it on.

When configuring the 1734-AENTR module, it can be set up through the Studio 5000 software. For example, after creating a new project, add the 1734-AENTR Module to the Ethernet network, enter the module name and IP address, and then select "Compatible Module" in "Elcetronic Keying" and set "Chassis Size".

Please note that although the 1715-AENTR and 1734-AENTR modules are similar in name, they belong to different product families and have different functions and application scenarios. The 1715-AENTR is an Ethernet /IP adapter module for redundant I/O systems, while the 1734-AENTR is a remote I/O module commonly used for remote communication and data acquisition in ControlLogix systems.
