Allen-Bradley 1747-ASB 是一个远程 I/O 适配器模块，是 SLC 500 系统的一部分。它通过远程 I/O 在 SLC 或 PLC 扫描仪和各种 1746 I/O 模块之间建立通信链路。远程 I/O 链路由一个主设备（即 SLC 或 PLC 扫描仪）和一个或多个作为适配器的从设备组成。SLC 或 PLC 映像表直接从其机箱获取 I/O 模块映像映射。对于映像映射，它支持离散和块传输。1747-ASB 支持 1/2 插槽、1 插槽和 2 插槽寻址，具有高效的映像利用率。它安装在带有SLC 500处理器的机箱中，并扫描机箱中的I / O。

1747-ASB 模块在 375V 时具有 5 mA 背板电流，在 0V 时具有 24 mA 背板电流。它的zui小和zui大散热量为 1.875 W。它可以在zui远 3040 米的距离内传输 I/O 数据，并支持 57.6K、115.2K 和 230.4K 波特率。它允许用户选择多达 32 个逻辑组的映像大小，并控制多达 30 个机箱插槽。1747-ASB 还提供非易失性存储器和扩展节点功能，zui多可支持 32 个适配器。对于接线，必须使用百通9463或类似类别的电缆，并且不需要任何用户编程。它使用 6 针凤凰连接器连接远程 I/O 链路和处理器。1747-ASB 模块支持所有 SLC 501 I/O 模块，如基本模块、电阻模块、高速计数器模块等。对于故障排除和操作，它具有三个 7 段显示器，具有增强的显示操作状态和错误的功能。1747-ASB 适用于工业环境，并提供 NEMA 标准抗噪能力。

1747- ASB 是属于 SLC 500 自动化平台的远程 IO 适配器。此 IO 适配器与 I/O 扫描仪模块、接口卡和网关通信，以建立远程 IO 连接。

对于 PLC 应用，此模块的主要用途是通过远程 I/O 网络实现分布式 IO 应用。与 SLC 扩展总线相比，扩展的电缆长度有限，SLC 机箱扩展非常有限。使用 1747-ASB，zui多可以使用 32 个带有 1747 RIO 扫描仪的 SLC 机箱，适用距离为 762 米或 2500 英尺（230.4 KBaud）、1524 米或 5000 英尺（115.2 KBaud）和 3048 米或 10,000 英尺（57.6 KBaud）。此适配器的控制功能zui多为 30 个，此 30 个插槽限制可以分段到不同的机箱或机架，每个机架都安装了 RIO 扫描器和电源。

除了与远程IO扫描仪通信外，该模块还可用于与直接安装到个人计算机上的Allen-Bradley通信卡进行通信。这可以实现远程编程和配置功能，以及通过监控和数据采集（SCADA）进行远程控制。或者，Allen-Bradley人机界面（HMI）如PanelView产品能够添加远程I / O适配器，允许HMI控制类似于SCADA系统的过程。

此远程 I/O 适配器还支持与 Allen-Bradley 的通信，包括合作伙伴产品以及第三方网关和转换器，用于实现与其他自动化产品的第三方通信。

Allen-Bradley 1747-ASB is a remote I/O adapter module that is part of the SLC 500 system. It establishes communication links between SLC or PLC scanners and various 1746 I/O modules via remote I/O. A remote I/O link consists of a master device (i.e., an SLC or PLC scanner) and one or more slave devices that act as adapters. The SLC or PLC map table gets the I/O module map directly from its chassis. For mapping, it supports discrete and block transfers. The 1747-ASB supports 1/2 slot, 1 slot, and 2 slot addressing for efficient image utilization. It is installed in a case with an SLC 500 processor and scans for I/O in the case.

The 1747-ASB module has a backplane current of 5 mA at 375V and 24 mA at 0V. Its minimum and maximum heat dissipation are 1.875 W. It can transmit I/O data over distances of up to 3040 meters and supports 57.6K, 115.2K and 230.4K baud rates. It allows users to select image sizes for up to 32 logical groups and control up to 30 chassis slots. The 1747-ASB also offers non-volatile memory and expansion node capabilities, supporting up to 32 adapters. For wiring, a Belton 9463 or similar category cable must be used and does not require any user programming. It uses a 6-pin Phoenix connector to connect remote I/O links and processors. The 1747-ASB module supports all SLC 501 I/O modules such as base module, resistance module, high speed counter module, etc. For troubleshooting and operation, it has three 7-segment displays with enhanced capabilities to display operational status and errors. The 1747-ASB is suitable for industrial environments and provides NEMA standard noise resistance.

The 1747-ASB is a remote IO adapter for the SLC 500 automation platform. This IO adapter communicates with the I/O scanner module, interface card, and gateway to establish a remote IO connection.

For PLC applications, the main use of this module is to implement distributed IO applications through remote I/O networks. Compared to the SLC expansion bus, the extended cable length is limited, and the SLC chassis expansion is very limited. With the 1747-ASB, you can use up to 32 SLC cases with the 1747 RIO scanner, Applicable distances are 762 m or 2,500 ft (230.4 KBaud), 1524 m or 5,000 ft (115.2 KBaud) and 3048 m or 10,000 ft (57.6 KBaud). The control functions of this adapter are up to 30, and this 30 slot limit can be segmented into different chassis or racks, each of which is equipped with a RIO scanner and power supply.

In addition to communicating with the remote IO scanner, the module can also be used to communicate with the Allen-Bradley communication card installed directly on the personal computer. This enables remote programming and configuration functions, as well as remote control via supervisory Control and Data Acquisition (SCADA). Alternatively, Allen-Bradley human machine interfaces (HMI) such as PanelView products are capable of adding remote I/O adapters that allow the HMI to control processes similar to SCADA systems.

This remote I/O adapter also supports communication with Allen-Bradley, including partner products as well as third-party gateways and converters for third-party communication with other automation products.
