>>>>>型號(hào):1756-CNBD 橋接模塊 網(wǎng)絡(luò)的接口模塊

【功能描述】

Allen-Bradley 1756-CNB 或 ControlNet 橋接模塊是用于將 ControlLogix 機(jī)架連接到 ControlNet 網(wǎng)絡(luò)的接口模塊。與 Allen-Bradley 1756-CNBR 模塊相比，1756-CNB 用于標(biāo)準(zhǔn)的非冗余配置。如果用戶(hù)應(yīng)用程序每個(gè)通信模塊有 40 到 48 個(gè) 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(gè)可用節(jié)點(diǎn)。1756-CNB 模塊處理 2 件事，即當(dāng) I/O 數(shù)據(jù)與 Logix5550 控制器一起用于計(jì)劃數(shù)據(jù)和非計(jì)劃數(shù)據(jù)時(shí)，在 ControlLogix 背板和 ControlNet 網(wǎng)絡(luò)之間橋接數(shù)據(jù)。請(qǐng)確保路徑信息正確無(wú)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(shè)備的 64 個(gè)雙向連接。它可以是計(jì)劃內(nèi)連接和計(jì)劃外連接的混合。但是，支持的連接數(shù)還取決于網(wǎng)絡(luò)配置。如果應(yīng)用程序需要更多連接，用戶(hù)可以添加另一個(gè) 1756-CNB 模塊，但他們必須確保在與第一個(gè)模塊相同的機(jī)箱和同一網(wǎng)絡(luò)上執(zhí)行此操作。對(duì)于未連接的消息，它還可以支持多達(dá) 20 個(gè)緩沖區(qū)。它還具有 2 個(gè)端口 - 1 個(gè) ControlNet BNC 端口和 1 個(gè) ControlNet RJ45 端口。用戶(hù)在安裝1756-CNB模塊時(shí)，需要先設(shè)置模塊的節(jié)點(diǎn)地址開(kāi)關(guān)。他們可以從 01 到 99 中選擇唯一的節(jié)點(diǎn)地址。然后，用戶(hù)可以通過(guò)使用 1 組模塊將該模塊用作獨(dú)立控制模塊，或者通過(guò)使用相同的模塊對(duì)（合作伙伴）將其用作冗余控制設(shè)置。請(qǐng)注意，使用冗余控制時(shí)，節(jié)點(diǎn)地址交換機(jī)應(yīng)具有相同的節(jié)點(diǎn)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(jī)架連接到 ControlNet 數(shù)據(jù)高速公路。該模塊是一個(gè)單插槽模塊，帶有一 （1） 個(gè)用于非冗余介質(zhì)操作的 BNC 連接器和一 （1） 個(gè) 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).
