Allen-Bradley（羅克韋爾自動化的一個部門）的1715-AENTR 是一款冗余 I/O 系統(tǒng)的以太網(wǎng)/IP 適配器通信模塊。這個模塊支持設備級環(huán)網(wǎng)（DLR）或星形拓撲，并且具有自動感應 10/100BASE-TX 以太網(wǎng)端口 。1715-AENTR 模塊充當所有進出冗余 I/O 模塊的以太網(wǎng) I/P 消息的“代理”模塊，是專門為 ControlLogix 系列可編程自動化控制器（PAC）設計的。通過實施冗余 I/O 系統(tǒng)和冗余通信網(wǎng)絡，可以延長流程的正常運行時間并降低不必要的系統(tǒng)停機風險 。
1715-AENTR 模塊在單工模式下使用時，可以配置冗余以太網(wǎng)網(wǎng)絡。如果使用雙工模式，兩個適配器模塊中的一個出現(xiàn)故障不會影響整個通信網(wǎng)絡，從而提高系統(tǒng)可用性 。該模塊非常靈活，支持各種配置，包括雙工端接適配器、雙工輸入模塊和雙工輸出模塊，且不需要復雜的編程或交叉布線 I/O 。
此外，1715-AENTR 模塊還具備高級診斷功能，包括設備智能等，通過內(nèi)部診斷實現(xiàn)狀態(tài)監(jiān)控，并對可能引起問題的當前異常（開路/短路、閾值或變化率）提供特殊警報 。
對于 1734-AENTR 模塊的配置，它具有兩個網(wǎng)口、三個撥碼開關和五個狀態(tài)指示燈。當模塊需要設置 IP 地址時，可以通過撥碼開關設置，例如，設置為 192.168.1.100 時，將撥碼設置為 100，然后使用 BootP 軟件進行 IP 地址設置 。如果需要恢復模塊到出廠設置，可以在通電的情況下將撥碼設為 888，然后斷電再上電 。
在配置 1734-AENTR 模塊時，可以通過 Studio 5000 軟件進行設置。例如，新建一個項目后，在 Ethernet 網(wǎng)絡中添加 1734-AENTR 模塊，并輸入模塊名稱和 IP 地址，然后在“Elcetronic Keying”中選擇“Compatible Module”并設置“Chassis Size” 。
請注意，雖然 1715-AENTR 和 1734-AENTR 模塊在名稱上相似，但它們屬于不同的產(chǎn)品系列，具有不同的功能和應用場景。1715-AENTR 是冗余 I/O 系統(tǒng)的以太網(wǎng)/IP 適配器模塊，而 1734-AENTR 是遠程 I/O 模塊，通常用于 ControlLogix 系統(tǒng)的遠程通信和數(shù)據(jù)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.
