品牌 ：GE发那科
系列 ：90-70系列
零件编号： IC697BEM742
描述 ：FIP 总线控制器
应用 ：FIP 或 World FIP I/O 串行总线
工作电压 ：5.0 伏直流电
IC697BEM742 FIP总线控制器是一种用于协调计算机系统内部各组件之间数据传输和处理的设备。在FIP(如WorldFIP现场总线)系统中，总线控制器起着至关重要的作用。
WorldFIP现场总线是一种用于现场仪表与控制系统和控制室之间的全分散、全数字化、智能、双向、互联、多变量、多点、多站的通信系统。它采用标准的通信协议，如HDLC(双环四分组格式)和基于以太网的标准TCP/IP协议，这些协议可以支持高速数据传输，提高通信效率。
在WorldFIP现场总线中，IC697BEM742 总线控制器通过串行通信方式，利用双绞线、光纤或无线通信介质进行数据传输。在数据传输过程中，设备之间会交换数据包，每个数据包包含一组特定的信息，如传感器读数、控制指令等。总线控制器会向各个组件发送信号，通知它们何时可以开始数据的传输和处理，以及传输的方式和格式等。同时，总线控制器还会负责对传输过程中出现的错误进行检测和纠正。

Part number: IC697BEM742
Description: FIP bus controller
Application: FIP or World FIP I/O serial bus
Operating voltage: 5.0V DC
The IC697BEM742 FIP bus controller is a device used to coordinate data transmission and processing between components within a computer system. In FIP (such as WorldFIP Fieldbus) system, bus controller plays a crucial role.
WorldFIP fieldbus is a fully decentralized, fully digital, intelligent, bidirectional, interconnected, multi-variable, multi-point, multi-station communication system used between the field instrument and the control system and the control room. It uses standard communication protocols such as HDLC (double loop four packet format) and the standard Ethernet-based TCP/IP protocol, which can support high-speed data transmission and improve communication efficiency.
In the WorldFIP fieldbus, the IC697BEM742 bus controller uses twisted pair, optical fiber or wireless communication medium for data transmission through serial communication. During data transmission, packets are exchanged between devices, and each packet contains a specific set of information, such as sensor readings, control instructions, and so on. The bus controller sends a signal to each component informing them when they can begin data transmission and processing, as well as the mode and format of transmission. At the same time, the bus controller is also responsible for detecting and correcting errors that occur during transmission.
