1756-CNBR/E 通信接口模块 控制网桥冗余

☆型号：1756-CNBR/E  通信接口模块 控制网桥冗余

【产品详情】

1756-CNBR，或控制网桥冗余，是一种用于在控制网网络内通信的接口模块。它与1756-CNB相同，但最大的区别是1756-CNBR有一个额外的ControlNet端口，它将支持冗余介质。该模块有两个控制网络BNC端口，而1756-CNB只有一个，尽管它们都有一个控制网络RJ45端口。

与非冗余模块一样，1756-CNBR也与Logix5550控制器一起控制预定数据，并在ControlLogix底板和ControlNet网络之间桥接非预定数据。

为了防止分路器或中继线路断开时通信丢失，可以使用冗余的ControlNet介质。对于这种连接，您可以使用的唯一模块是1756-CNBR。

该模块的技术规格也类似于非冗余模块。它还可以处理多达64个与其他ControlNet设备的双向预定和非预定连接。除此之外，该模块最多可支持20个未连接消息的缓冲区。此外，如果您的应用程序每个通信模块有40到48个Logix通信连接，并且通信速率为每秒5兆字节，则这是所需的模块。它还有99个可用节点。

1756-CNBR的电流消耗在5.1伏DC时为970毫安，在24伏DC时为1.7毫安。

进行连接之前，请务必检查分支电缆上是否有指示连接段的标签。这是为了确保分接头连接不会意外颠倒。否则，这些反转将需要故障排除，并且状态将显示不正确。

艾伦-布拉德利1756-CNBR是一个控制网桥模块。该模块是ControlLogix产品系列的一部分，用于通过高速ControlNet网络连接ControlLogix控制器或实现分布式I/O架构。该模块具有两(2)个控制网络端口，能够连接到标准(单工)和冗余控制网络。

1756-CNBR支持5Mbps的传输速率，这是ControlNet协议的标准传输速率。它使用四屏蔽RG-6同轴电缆作为中继电缆，并使用ControlNet分路器与中继电缆建立连接。该模块支持40-48个逻辑通信连接和最多64个连接。1756 CNBR支持的最大节点数是99个节点。

【英文介绍】

The 1756-CNBR, or Control bridge redundancy, is an interface module for communication within a control network. It is the same as the 1756-CNB, but the biggest difference is that the 1756-CNBR has an additional ControlNet port, which will support redundant media. The module has two control network BNC ports, while the 1756-CNB has only one, although they both have a control network RJ45 port.

Like the non-redundant modules, the 1756-CNBR also controls scheduled data with the Logix5550 controller and Bridges unscheduled data between the ControlLogix mainboard and the ControlNet network.

To prevent communication loss when the splitter or trunk line is disconnected, redundant ControlNet media can be used. The only module you can use for this connection is the 1756-CNBR.

The technical specifications of the module are also similar to non-redundant modules. It can also handle up to 64 two-way scheduled and unscheduled connections to other ControlNet devices. In addition, the module can support a buffer of up to 20 unconnected messages. Also, if your application has 40 to 48 Logix communication connections per communication module and a communication rate of 5 megabytes per second, this is the module you need. It also has 99 nodes available.

The current consumption of the 1756-CNBR is 970 mA at 5.1 volts DC and 1.7 MA at 24 volts DC.

Before connecting, be sure to check that the branch cable has a label indicating the connection segment. This is to ensure that the tap connection is not accidentally reversed. Otherwise, these inversions will require troubleshooting, and the status will display incorrectly.

The Allen Bradley 1756-CNBR is a control bridge module. This module is part of the ControlLogix product family and is used to connect ControlLogix controllers over high-speed ControlNet networks or to implement distributed I/O architectures. The module has two (2) control network ports capable of connecting to both standard (simplex) and redundant control networks.

The 1756-CNBR supports a transfer rate of 5Mbps, which is standard for the ControlNet protocol. It uses the four-shielded RG-6 coaxial cable as the trunk cable and uses the ControlNet splitter to establish a connection to the trunk cable. The module supports 40-48 logical communication connections and up to 64 connections. 1756 The CNBR supports a maximum of 99 nodes.
