Allen-Bradley 1769-SDN 是一款 PLC，用作 CompactLogix DeviceNet 扫描器通信模块。通过 1769-SDN，可以在 CompactLogix 控制器、MicroLogix 1500 可编程控制器和 DeviceNet 设备之间进行通信。该模块尺寸为 118x 87 x 35 毫米，包括其 138 毫米的安装片。该模块重约 280 克或 0.61 磅，在 5 伏直流电（2.2 瓦）下的最大总线电流消耗为 440 mA，最大散热为 3.8 瓦。

1769-SDN 不应安装在环境大气中含有挥发性或腐蚀性气体、蒸气或灰尘的任何地方。1769-SDN 的工作温度为 0 至 60 摄氏度或 32 至 140 华氏度，不应存放在腐蚀性环境中的任何地方。此模块与连接的 PowerFlex 4 类变频器之间的最大电缆距离为 10 米。最大电缆长度必须在 500K 波特率下为 125 米，在 100K 波特率下必须为 500 米。1769-SDN 距离电源的距离不能超过 4 个模块，因此其电源距离额定值为 4。其 DeviceNet 功率要求为 N.E.C. 2 类 11 V DC 时为 90 mA，25 V DC 时为 110 mA，1.5 毫秒时为 200 mA。1769-SDN能够在从设备中读取输入和写入输出，与对等设备通信，并通过给定的DeviceNet网络将程序加载到基于1764-LRP的控制器。

Allen-Bradley 1769-SDN 是一款 CompactLogix 通信模块。具体来说，该模块是一个 DeviceNet 扫描仪模块，用于与其他 DeviceNet 适配器和其他支持 DeviceNet 的设备（如可调频率交流驱动器、伺服驱动器和其他设备）交换信息。该扫描仪用作 DeviceNet 设备与其所连接的可编程控制器之间的接口。

DeviceNet 扫描程序通过搜索正确配置的 DeviceNet 适配器建立了与网络的连接。扫描程序发送选通、轮询、状态更改或循环 I/O 消息，以请求数据并将其传送到网络中的每个设备。接收到的数据被收集和组织，然后由处理器访问，以实现与所收集数据相关的特定用户逻辑。

Allen-Bradley 1769-SDN is a PLC used as a communication module for the CompactLogix DeviceNet scanner. With 1769-SDN, you can communicate between CompactLogix controllers, MicroLogix 1500 programmable controllers, and DeviceNet devices. The module measures 118x 87 x 35mm, including its 138mm mounting piece. The module weighs about 280 grams or 0.61 pounds and has a maximum bus current consumption of 440 mA at 5 volts direct current (2.2 watts) and a maximum heat dissipation of 3.8 watts.

1769-SDN should not be installed anywhere where the ambient atmosphere contains volatile or corrosive gases, vapors, or dust. The 1769-SDN operates at a temperature of 0 to 60 degrees Celsius or 32 to 140 degrees Fahrenheit and should not be stored anywhere in corrosive environments. The maximum cable distance between this module and the connected PowerFlex Class 4 inverter is 10 meters. The maximum cable length must be 125 meters at 500K baud rate and 500 meters at 100K baud rate. The 1769-SDN cannot be more than 4 modules away from the power supply, so its power distance rating is 4. Its DeviceNet power requirements are 90 mA for N.E.C. Class 2 at 11 V DC, 110 mA for 25 V DC, and 200 mA for 1.5 ms. The 1769-SDN is capable of reading inputs and writing outputs from a device, communicating with a peer device, and loading programs into a 1764-LRP-based controller over a given DeviceNet network.

Allen-Bradley 1769-SDN is a CompactLogix communication module. Specifically, the module is a DeviceNet scanner module for exchanging information with other DeviceNet adapters and other Devicenet-enabled devices such as tunable AC drives, servo drives, and other devices. The scanner acts as an interface between the DeviceNet device and the programmable controller to which it is connected.

The DeviceNet scanner establishes a connection to the network by searching for the correctly configured DeviceNet adapter. The scanner sends strobes, polls, status changes, or loop I/O messages to request data and deliver it to each device in the network. The received data is collected and organized, and then accessed by the processor to implement specific user logic related to the collected data.
