1794-ASB 是 AB 远程 I/O 通信适配器模块
1794-ASB 是艾伦-布拉德利远程 I/O 通信适配器模块。本产品属于分布式 I/O 模块的 Flex I/O 产品系列。
1794-ASB 具有一 (1) 个远程 I/O 接口。此RIO协议是传统协议,使用百通9463或等效电缆将设备连接到RIO扫描仪。该模块兼容艾伦-布拉德利传统控制器,如 PLC2、PLC3 和 PLC5 控制器以及 SLC500 自动化平台。它也可以用于现代 Logix 控制器平台以及第三方设备,并包含合作伙伴模块。
3-ASB 通过块传输读取 (BTR) 和块传输写入 (BTW) 指令向控制器发送和接收数据。使用这些指令,可以根据所需的速度同时或顺序发送数据包。
1794-ASB 支持 1794.57Kbps、6.115Kbps 和 2.230kbps 的通信速率。该模块的预期电源电压范围为 4VDC-11.31VDC,包括 2% 交流纹波,而标称电源为 5VDC。它支持安装多达八 (24) 个 Flex I/O 模块,以成功实施分布式 I/O 架构。该模块具有内置状态指示灯,如电源指示灯、适配器活动指示灯、适配器故障指示灯和本地故障指示灯。该模块安装在标准DIN导轨上,并具有开放式外壳,这意味着8-ASB需要安装在适当的外壳内,以保护设备免受工业元件和污染物的影响。

The 1794-ASB is an Allen-Bradley Remote I/O communication adapter module. This product belongs to the Flex I/O product family of distributed I/O modules.
The 1794-ASB has one (1) remote I/O interface. This RIO protocol is traditional and uses a Belton 9463 or equivalent cable to connect the device to the RIO scanner. The module is compatible with Allen-Bradley legacy controllers such as PLC2, PLC3 and PLC5 controllers as well as the SLC500 automation platform. It can also be used on modern Logix controller platforms as well as third-party devices and includes partner modules.
3-ASB sends and receives data to the controller via block transfer Read (BTR) and block Transfer Write (BTW) instructions. Using these instructions, packets can be sent simultaneously or sequentially according to the desired speed.
The 1794-ASB supports 1794.57Kbps, 6.115Kbps, and 2.230kbps communication rates. The module has an expected power supply voltage range of 4VC-11.31 VDC, including 2% AC ripple, compared to a nominal power supply of 5VDC. It supports the installation of up to eight (24) Flex I/O modules to successfully implement a distributed I/O architecture. The module has built-in status indicators such as power indicator, adapter activity indicator, adapter failure indicator and local failure indicator. The module is mounted on a standard DIN rail and has an open housing, which means the 8-ASB needs to be installed in a proper housing to protect the device from industrial components and contaminants.
