1788-DNBO 是一个DeviceNet子卡

Allen-Bradley 1786-DNBO是一个DeviceNet子卡。此子卡可与任何兼容的Allen-Bradley设备一起使用，该设备可容纳此模块。

对于DeviceNet子卡的配置，需要安装RSNetWorx For DeviceNet V3.0 Service Pack 2。这是将模块包含到系统扫描列表中所必需的。

为了设置1788-DNBO的网络地址，配置两台交换机配置1788-DNBO。有效的节点地址为0 ~ 63，这是DeviceNet网络支持的节点范围。作为一般规则，子卡的节点地址必须是唯一的，并且在网络中不能有重复的地址。另外，将节点地址设置为99，重新启动模块，将硬盘擦除到定义的扫描列表中，因此，只有在需要擦除到扫描列表时才需要进行此操作。在上电期间读取开关设置，以识别子卡的设置地址和预期操作。

网络传输速率可以使用不同的硬件开关配置，也安装在子卡中。该开关位于可移动连接器旁边，允许设置速度，例如设置为0(0)时125 Kb，设置为1(1)时250Kb，设置为2(2)时500 Kb。同样，在模块启动期间读取开关设置。

子卡提供NS (Network status)、I/O状态指示灯等状态指示灯。网络状态指示灯是一种双色LED，一般用于显示通信链路的状态。I/O状态指示灯也是一个双色LED，表示I/O扫描速度。

1788-DNBO子卡提供可选择的波特率和节点(0 = 125k, 1 = 250k, 2 = 500k)，可以通过板上的硬件推轮设置，它的输入和输出数据速率为124双整数(DINT)和123 DINT。1788-DNBO子卡通过工厂提供的5针DeviceNet连接器电缆连接到DeviceNet网络，该电缆连接到扫描仪上的DeviceNet端口，并用连接器螺钉拧紧。具有网络状态指示灯(NW)、模块状态指示灯(MS)和I/O状态指示灯，用于反映卡的性能状态。1788-DNBO子卡的工作温度范围为0至60摄氏度，可在-40至85摄氏度的温度范围内存储。净重0.1公斤，通过CE、c-UR-us、C-TICK、ODVA认证。

1788-DNBO 是一个DeviceNet子卡

Allen-Bradley 1786-DNBO is a DeviceNet daughter card. This sub-card can be used with any compatible Allen-Bradley device that houses this module.

For the configuration of DeviceNet subcards, you need to install RSNetWorx For DeviceNet V3.0 Service Pack 2. This is required to include the module in the system scan list.

To set the 1788-DNBO network address, configure two switches to configure 1788-DNBO. Valid node addresses range from 0 to 63, which is the range of nodes supported by the DeviceNet network. As a general rule, the node address of the child card must be unique, and there must be no duplicate address in the network. In addition, set the node address to 99, restart the module, and erase the hard disk into the defined scan list, so you only need to do this if you need to erase it into the scan list. The switch Settings are read during power-on to identify the set address and expected operation of the sub-card.

The network transfer rate can be configured using different hardware switches, also installed in the sub-card. This switch is located next to the removable connector and allows the speed to be set, for example 125 Kb when set to 0(0), 250Kb when set to 1(1), and 500 Kb when set to 2(2). Similarly, the switch Settings are read during module startup.

The subcard provides status indicators, such as Network status (NS) and I/O status indicators. The network status indicator is a two-color LED that is generally used to display the status of a communication link. The I/O status indicator is also a two-color LED that indicates the I/O scanning speed.

The 1788-DNBO subcard offers selectable baud rates and nodes (0 = 125k, 1 = 250k, 2 = 500k) that can be set via an on-board hardware pushwheel, and its input and output data rates are 124 double integer (DINT) and 123 DINT. The 1788-DNBO subcard is connected to the DeviceNet network via a factory-supplied 5-pin DeviceNet connector cable that connects to the DeviceNet port on the scanner and is tightened with connector screws. The network status indicator (NW), module status indicator (MS) and I/O status indicator are used to reflect the performance status of the card. The 1788-DNBO sub-card operates in a temperature range of 0 to 60 degrees Celsius and can be stored in a temperature range of -40 to 85 degrees Celsius. Net weight 0.1kg, passed CE, c-UR-us, C-TICK, ODVA certification.
