IC697BEM733 | 远程 I/O 扫描器模块 可编程逻辑控制器 (PAC) 

　　该IC697BEM733是一个远程 I/O 扫描器模块，是 90-70 系列可编程逻辑控制器 (PAC) 系列的一部分，该系列以前由 GE Fanuc Automation 制造，现在隶属于 Emerson Automation。该模块是一个远程 I/O 扫描器，提供一个 15 针 RS-422/485 兼容串行端口和一 (1) 个 9 针 IC66* 手持显示器端口。它还有一个用于总线通信的 IC66* 总线端子。该模块支持安装在距离控制器 7500 英尺(2275 米)的地方，并处理每个远程 I/O 掉落 128 字节的输入和输出。

　　IC697BEM733 远程I/O扫描器模块是一种用于实现远程数据采集和控制的设备。它通常由硬件模块和软件驱动程序组成，可以将外部传感器或执行器与远程计算机或控制系统连接起来。

　　这种模块具有通信功能的数据采集/传送能力，可以将现场数据送到控制中心(如PLC)，或者接受控制中心的数据对现场设备进行控制。通信方式多种多样，如自由口通信、PROFIBUS、MODBUS等，取决于不同厂家的标准。

　　IC697BEM733 远程I/O扫描器模块的应用广泛，包括楼宇自动化、智能交通、水处理系统、高速公路智能系统、能源管理系统、环境监测和工厂自动化等领域。在这些场合中，远程I/O扫描器模块可以帮助节省布线、节省PLC自身的I/O点数，提高过程监控质量，防止出错并避免因产品不合格或后续补救工作而产生的额外成本

　　The IC697BEM733 is a remote I/O scanner module that is part of the 90-70 series Programmable Logic Controller (PAC) family, formerly manufactured by GE Fanuc Automation and now owned by Emerson Automation. The module is a remote I/O scanner that offers a 15-pin RS-422/485 compatible serial port and one (1) 9-pin IC66* handheld display port. It also has an IC66* bus terminal for bus communication. The module supports installation up to 7,500 feet (2,275 meters) from the controller and handles 128 bytes of input and output per remote I/O drop.

　　The IC697BEM733 Remote I/O scanner module is a device for remote data acquisition and control. It usually consists of hardware modules and software drivers that can connect external sensors or actuators to remote computers or control systems.

　　This module has the data acquisition/transmission capability of communication function, which can send the field data to the control center (such as PLC), or accept the data of the control center to control the field equipment. There are a variety of communication methods, such as free port communication, PROFIBUS, MODBUS, etc., depending on the standards of different manufacturers.

　　The IC697BEM733 remote I/O scanner module is used in a wide range of applications, including building automation, intelligent transportation, water treatment systems, intelligent highway systems, energy management systems, environmental monitoring and factory automation. In these cases, the remote I/O scanner module can help save wiring, save the PLC's own I/O points, improve the quality of process monitoring, prevent errors and avoid additional costs due to product nonconformity or subsequent remedial work
