【功能描述】

Allen-Bradley 1756-CNB 或 ControlNet 橋接模塊是用于將 ControlLogix 機架連接到 ControlNet 網(wǎng)絡的接口模塊。與 Allen-Bradley 1756-CNBR 模塊相比，1756-CNB 用于標準的非冗余配置。如果用戶應用程序每個通信模塊有 40 到 48 個 Logix 通信連接，則該模塊是完美的選擇。它的通信速率為每秒 5 兆字節(jié)，并且有 99 個可用節(jié)點。1756-CNB 模塊處理 2 件事，即當 I/O 數(shù)據(jù)與 Logix5550 控制器一起用于計劃數(shù)據(jù)和非計劃數(shù)據(jù)時，在 ControlLogix 背板和 ControlNet 網(wǎng)絡之間橋接數(shù)據(jù)。請確保路徑信息正確無誤，以便正確路由它收到的消息。

1756-CNB 模塊最多可支持與其他 ControlNet 設備的 64 個雙向連接。它可以是計劃內(nèi)連接和計劃外連接的混合。但是，支持的連接數(shù)還取決于網(wǎng)絡配置。如果應用程序需要更多連接，用戶可以添加另一個 1756-CNB 模塊，但他們必須確保在與第一個模塊相同的機箱和同一網(wǎng)絡上執(zhí)行此操作。對于未連接的消息，它還可以支持多達 20 個緩沖區(qū)。它還具有 2 個端口 - 1 個 ControlNet BNC 端口和 1 個 ControlNet RJ45 端口。用戶在安裝1756-CNB模塊時，需要先設置模塊的節(jié)點地址開關(guān)。他們可以從 01 到 99 中選擇唯一的節(jié)點地址。然后，用戶可以通過使用 1 組模塊將該模塊用作獨立控制模塊，或者通過使用相同的模塊對（合作伙伴）將其用作冗余控制設置。請注意，使用冗余控制時，節(jié)點地址交換機應具有相同的節(jié)點地址。1756 伏直流電下的 5.1-CNB 電流消耗為 970 毫安，如果電流消耗為 24 伏直流電，則為 1.7 毫安。其額定功耗為 5.14 瓦。

1756-CNB 是一款 ControlLogix 通信適配器，用于將任何 ControlLogix 機架連接到 ControlNet 數(shù)據(jù)高速公路。該模塊是一個單插槽模塊，帶有一 （1） 個用于非冗余介質(zhì)操作的 BNC 連接器和一 （1） 個 NAP（RJ-45 8 針，帶屏蔽）的集成通信端口。

【英文介紹】

The Allen-Bradley 1756-CNB or ControlNet Bridge module is an interface module used to connect the ControlLogix rack to the ControlNet network. Compared to the Allen-Bradley 1756-CNBR module, the 1756-CNB is used in a standard non-redundant configuration. If the user application has 40 to 48 Logix communication connections per communication module, this module is the perfect choice. It has a communication rate of 5 megabytes per second and has 99 nodes available. The 1756-CNB module handles 2 things, namely bridging data between the ControlLogix backplane and the ControlNet network when I/O data is used with the Logix5550 controller for planned and unplanned data. Make sure that the path information is correct so that it can correctly route the messages it receives.

The 1756-CNB module supports up to 64 bidirectional connections with other ControlNet devices. It can be a mix of planned and unplanned connections. However, the number of connections supported also depends on the network configuration. If the application needs more connections, users can add another 1756-CNB module, but they must make sure to do so in the same chassis and on the same network as the first module. It can also support up to 20 buffers for unconnected messages. It also has 2 ports - 1 ControlNet BNC port and 1 ControlNet RJ45 port. Before installing the 1756-CNB module, you need to set the node address switch of the module. They can select unique node addresses from 01 to 99. The user can then use this module as an independent control module by using 1 set of modules, or as a redundant control setting by using the same pair of modules (partners). Note that when using redundant control, the node address switch should have the same node address. The current consumption of 5.1-CNB at 1756 volts DC is 970 mA, or 1.7 mA if the current consumption is 24 volts DC. Its power consumption rating is 5.14 watts.

The 1756-CNB is a ControlLogix communications adapter for connecting any ControlLogix rack to the ControlNet data highway. The module is a single slot module with one (1) BNC connector for non-redundant media operation and one (1) integrated communication port for NAP (RJ-45 8-pin, shielded).
