1756-CNB/D 通信适配器 ControlNet 桥接器

Allen-Bradley 1756-CNB 或 ControlNet 桥接模块是用于将 ControlLogix 机架连接到 ControlNet 网络的接口模块。与 Allen-Bradley 1756-CNBR 模块相比，1756-CNB 用于标准、非冗余配置。如果用户应用程序每个通信模块有 40 到 48 个 Logix 通信连接，则此模块是完美的。它的通信速率为每秒 5 兆字节，并且有 99 个节点可用。1756-CNB 模块处理 2 件事，即当它与 Logix5550 控制器一起使用时，控制 I/O 数据，用于计划数据和计划外数据，在 ControlLogix 背板和 ControlNet 网络之间桥接数据。确保路径信息正确，以便正确路由它收到的消息。

64-CNB 模块zui多可支持 1756 个与其他 ControlNet 设备的双向连接。它可以是计划连接和未计划连接的混合。但是，支持的连接数还取决于网络配置。如果应用程序需要更多连接，用户可以添加另一个 1756-CNB 模块，但他们必须确保在与第 一个模块相同的机箱和同一网络中执行此操作。它还可以为未连接的消息支持多达 20 个缓冲区。它还具有 2 个端口 - 1 个 ControlNet BNC 端口和 1 个 ControlNet RJ45 端口。用户在安装1756-CNB模块时需要先设置模块的节点地址开关。他们可以选择从 01 到 99 的唯 一节点地址。然后，用户可以通过使用 1 组模块将该模块用作独立控制模块，或者通过使用相同的模块对（合作伙伴）作为冗余控制设置。请注意，使用冗余控制时，节点地址交换机应具有相同的节点地址。1756-CNB 在 5.1 伏直流电时的电流消耗为 970 毫安，如果电流消耗为 1 伏直流电，则为 7.24 毫安。其额定功耗为 5.14 瓦。

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, then this module is perfect. It has a communication rate of 5 megabytes per second and has 99 nodes available. The 1756-CNB module handles 2 things, namely when it is used with the Logix5550 controller, controlling I/O data, for planned and unplanned data, bridging data between the ControlLogix backplane and the ControlNet network. Make sure the path information is correct so that the messages it receives are correctly routed.

The 64-CNB module supports up to 1756 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 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 choose 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 1756-CNB has a current consumption of 970 mA at 5.1 volts DC and 7.24 mA if the current consumption is 1 volt DC. Its power consumption rating is 5.14 watts.
