1747-SDN 通信扫描器

概述：

Allen-Bradley 1747-SDN是一种DeviceNet通信扫描器。该扫描模块用于通过DeviceNet网络或通过DeviceNet适配器模块与支持DeviceNet的设备进行通信。该模块可以在从属模式下运行;在轮询、频闪、状态变化和循环I/O配置中发送和接收消息。它还支持直通配置，其中1747-SDN充当桥接器，连接单独的DeviceNet网络。该直通特性旨在取代网络上的1770-KFD、1784-PCD、1784-PCID或1784- pids DeviceNet连接。

具体来说，在实现直通配置时，兼容的SLC 500处理器是SLC 5/03、SLC 5/04和SLC 5/05。

1747-SDN支持最多配置63个节点，波特率为125kbps。它吸收背板电流达5V DC, 500 mA。

1747-SDN前面板上有2个LED状态指示灯(如模块指示灯)和1个Network状态LED(表示DeviceNet通信链路)。它也有一个液晶显示器，提供模块地址和错误指示。DeviceNet终端安装在门禁门后面，有一个10针线性插头插入DeviceNet端口。

它是SLC处理器和DeviceNet设备之间的接口，它可以通过M1/M0文件传输和离散I/O与处理器通信。1747-SDN与SLC 500处理器交换配置数据、设备I/O数据和状态信息。它在5伏直流电流下500mA的背板电流，在24伏直流电流下90mA的电流，并使用基本绝缘类型在devicenet到背板之间在500V交流下测试60秒，提供30伏电路隔离。1747-SDN具有IEC测试的工作温度范围在0至60摄氏度(32至140华氏度)之间，在5%至95%的非冷凝湿度下，它存储在-40至85摄氏度(-40-185华氏度)的温度范围内。它还具有iec测试的10-500Hz下2G的抗振能力和30G的最大冲击等级。它具有CISPR 11，第1组，a类排放等级，并指定为T5北美温度代码。它采用开放式外壳，并通过了c-UL-us和ce认证。

1747-SDN 通信扫描器

Allen-Bradley 1747-SDN is a DeviceNet communication scanner. The scan module is used to communicate with Devicenet-enabled devices through the DeviceNet network or through the DeviceNet adapter module. The module can be run in slave mode; Send and receive messages in polling, stroboscopic, state change, and cyclic I/O configurations. It also supports a pass-through configuration, where the 1747-SDN acts as a bridge, connecting separate DeviceNet networks. This pass-through feature is designed to replace 1770-KFD, 1784-PCD, 1784-PCID, or 1784-pids DeviceNet connections on the network.

Specifically, when implementing a pass-through configuration, the compatible SLC 500 processors are SLC 5/03, SLC 5/04, and SLC 5/05.

The 1747-SDN supports a maximum of 63 nodes with a baud rate of 125kbps. It absorbs backplane current up to 5V DC, 500 mA.

The 1747-SDN front panel has 2 LED status indicators (such as module indicators) and 1 Network status LED(indicating the DeviceNet communication link). It also has an LCD display that provides module addresses and error indications. The DeviceNet terminal is installed behind the access door and has a 10-pin linear plug that plugs into the DeviceNet port.

It is the interface between the SLC processor and the DeviceNet device, and it can communicate with the processor through M1/M0 file transfers and discrete I/O. The 1747-SDN exchanges configuration data, device I/O data, and status information with the SLC 500 processor. It runs at 500mA of backplane current at 5 volts DC and 90mA of current at 24 volts DC, and uses the basic insulation type to test at 500V AC between the devicenet and backplane for 60 seconds, providing 30 volts circuit isolation. The 1747-SDN has an IEC tested operating temperature range of between 0 and 60 degrees Celsius (32 to 140 degrees Fahrenheit), and it is stored in a temperature range of -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit) at 5% to 95% non-condensing humidity. It also has iec tested vibration resistance of 2G at 10-500Hz and a maximum impact rating of 30G. It has CISPR 11, Group 1, Class a emission rating and is designated as a T5 North American temperature code. It has an open housing and is c-UL-us and ce certified.
