1769-ADN DeviceNet适配器模块 开放的低级网络模块
【产品详情】
Allen-Bradley 1769-ADN 是 CompactLogix I/O DeviceNet 适配器模块。它是一个开放的低级网络模块，将简单的工业设备（如执行器和传感器）与高级设备（如计算机和PLC控制器）连接起来。它使用众所周知的通用工业协议 （CIP），为工业设备提供各种功能，例如控制、数据收集和配置。它将低级设备直接连接到工厂车间控制器，而不是通过 I/O 模块进行接口。数据根据需要通过此模块发送。1769-ADN 适配器模块的最大 DeviceNet 通信速率为 125 Kbps（500 米）、250 Kbps（250 米）和 500 Kbps（100 米）。它最多有 30 个 I/O 节点。它在 450 伏直流电下消耗 500 mA（A 系列）和 5 mA（B 系列）的电流。它的尺寸为 4.65 x 1.97 x 3.43 英寸。重0.6磅。
该模块在 90 伏直流电和 24 至 11 伏直流电压下的电流消耗为 25 mA。它具有 30 伏隔离电压和 4.7 瓦功耗。对于安装，它使用带有开放式外壳的DIN导轨或面板安装方法，并且在CompactLogix机箱中需要一个插槽。适配器与电源的距离不应超过 4 个模块（A 系列）或 5 个模块（B 系列）。1769-ADN 适配器模块具有更多诊断功能，可提供更好的故障检测和改进的数据收集。接线时，必须使用符合 802.3 标准的双绞线电缆，标准为 2 平方毫米 （14 AWG）。与普通的硬连线系统相比，它具有更短的启动时间和更少的布线。
Allen-Bradley 1769-ADN 是一款 DeviceNet 适配器，可与 1769 CompactLogix 或 MircoLogix 1500 自动化平台兼容。该模块允许控制器或任何兼容设备通过DeviceNet协议与现场仪表和基于计算机的控制系统进行通信和交换数据。
该模块支持使用 Allen-Bradley DeviceNet 电缆的 125k bit/s、250k bit/s 和 500k bit/s 的传输速度。这利用通用工业协议 （CIP） 作为主要通信主干，并利用合作伙伴与网络中现有的 DeviceNet 扫描仪模块合作。此适配器响应扫描仪（如 1769-SDN）的请求，以提供请求的数据。
该通信模块可用于接口并向属于1769平台的控制器发送消息。它还能够响应其他可编程逻辑控制器（PLC）产品系列（如PLC5，SLC500和ControLogix）的DeviceNet扫描仪。这是通过使用受支持的消息传递功能来实现的。
此适配器可安装在任何 1769 紧凑型 I/O 模块旁边。但是，必须满足电源距离额定值，即 4。这意味着模块不能安装在远离电源的 Frou （4） 模块以上。当与 MircoLogix 1500 一起使用时，模块安装在基础单元旁边或相邻模块上。
当 1769-AND 未正确安装时，会出现典型问题，尤其是 1769 CompactLogix 组件。将 1769-ADN 适配器安装到 CompactLogix 系统时，必须牢固锁定总线连接器以建立电气连接。如果在固定模块时感觉到阻力，请松开模块并检查 PIN 连接器是否正确对齐，然后再继续连接。

【英文介绍】
Allen-Bradley 1769-ADN is a CompactLogix I/O DeviceNet adapter module. It is an open low-level networking module that connects simple industrial devices, such as actuators and sensors, with advanced devices, such as computers and PLC controllers. It uses the well-known Common Industrial Protocol (CIP) to provide various functions for industrial equipment, such as control, data collection and configuration. It connects low-level devices directly to the factory floor controller instead of interfacing through an I/O module. Data is sent through this module as needed. The 1769-ADN adapter module has maximum DeviceNet communication rates of 125 Kbps (500 m), 250 Kbps (250 m), and 500 Kbps (100 m). It has a maximum of 30 I/O nodes. It consumes 500 mA (Series A) and 5 mA (Series B) at 450 volts DC. It measures 4.65 x 1.97 x 3.43 inches. It weighs 0.6 pounds.
The module has a current consumption of 25 mA at 90 volts DC and 24 to 11 volts DC. It has an isolation voltage of 30 volts and a power consumption of 4.7 watts. For mounting, it uses a DIN rail or panel mounting method with an open housing and requires a slot in the CompactLogix case. The adapter should not be more than 4 modules (Series A) or 5 modules (Series B) away from the power supply. The 1769-ADN adapter module has more diagnostic capabilities for better fault detection and improved data collection. When wiring, you must use an 802.3 compliant twisted pair cable with a standard of 2 square millimeters (14 AWG). It has a shorter startup time and less wiring than a normal hard-wired system.
Allen-Bradley 1769-ADN is a DeviceNet adapter that is compatible with the 1769 CompactLogix or MircoLogix 1500 automation platforms. The module allows the controller or any compatible device to communicate and exchange data with field instrumentation and computer-based control systems via the DeviceNet protocol.
The module supports 125k bit/s, 250k bit/s, and 500k bit/s transfer speeds using Allen-Bradley DeviceNet cables. This utilises the Common Industrial Protocol (CIP) as the main communication backbone and utilises partners to work with existing DeviceNet scanner modules in the network. This adapter responds to a request from a scanner, such as 1769-SDN, to provide the requested data.
This communication module can be used to interface and send messages to controllers belonging to the 1769 platform. It is also capable of responding to DeviceNet scanners from other programmable logic controller (PLC) product families such as PLC5, SLC500 and ControLogix. This is achieved by using supported messaging capabilities.
This adapter can be installed next to any 1769 compact I/O module. However, the power distance rating, i.e. 4, must be met. This means that the module cannot be installed above the Frou (4) module away from the power supply. When used with the MircoLogix 1500, the module is installed next to or adjacent to the base unit.
Typical problems occur when 1769-AND is not installed correctly, especially with the 1769 CompactLogix component. When installing the 1769-ADN adapter into a CompactLogix system, the bus connector must be firmly locked to establish an electrical connection. If you feel resistance while securing the module, release the module and check that the PIN connector is properly aligned before continuing the connection.
