1756-CNBR/D 通信模块 支持单工和冗余网络

☆型号：1756-CNBR/D 通信模块 支持单工和冗余网络

【产品详情】

 Allen-Bradley 1756-CNBR 是一款 ControlLogix 通信模块。该模块是一个 ControlNet Bridge 通信模块，具有两 （2） 个 ControlNet 端口，支持单工和冗余 ControlNet 网络。该模块还具有 1 个网络访问协议 （NAP），具有带屏蔽的 RJ-45 8 针物理接口。它支持 5Mbps 的通信速率和 40-48 个 ControlNet 逻辑连接。

Allen-Bradley 1756-CNBR 或 ControlNet 网桥冗余是用于在 ControlNet 网络内进行通信的接口模块。它与 1756-CNB 相同，但最大的区别是 1756-CNBR 有一个额外的 ControlNet 端口，它将支持冗余媒体。该模块有 2 个 ControlNet BNC 端口，而 1756-CNB 只有一个，尽管它们都有 1 个 ControlNet RJ45 端口。

与非冗余模块一样，1756-CNBR 还与 Logix5550 控制器一起控制计划数据，并在 ControlLogix 背板和 ControlNet 网络之间桥接计划外数据。

为防止分流器或干线断开时通信丢失，可以使用冗余的 ControlNet 介质。对于该连接，您可以使用的唯一模块是 1756-CNBR。

【英文介绍】

The Allen-Bradley 1756-CNBR is a ControlLogix communication module. This module is a ControlNet Bridge communication module with two (2) ControlNet ports that support simplex and redundant ControlNet networks. The module also has a Network Access Protocol (NAP) with a shielded RJ-45 8-pin physical interface. It supports a communication rate of 5Mbps and 40-48 ControlNet logical connections.

Allen-Bradley 1756-CNBR or ControlNet Bridge redundancy is an interface module for communication within the ControlNet 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 2 ControlNet BNC ports, while the 1756-CNB has only one, although they both have 1 ControlNet RJ45 port.

Like the non-redundant module, the 1756-CNBR also controls schedule data with the Logix5550 controller and Bridges unscheduled data between the ControlLogix backplane and the ControlNet network.

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