IC687BEM731-AB   天才总线控制器

该IC687BEM731是由GE自动化和控制公司制造的Genius总线控制器，与90-70系列或PACSystems RX7i系统兼容。 该IC687BEM731能够在一条Genius通信总线上与多达31个附加设备连接。此器件占用 PLC 背板上的单个插槽。通过Genius总线，IC687BEM731与多种类型的设备兼容，包括Genius I/O模块，各种其他可编程逻辑控制器，90-70系列系统的远程下降，Versamax I / O站，现场控制站以及其他几个需要数据报和全局数据进行通信的主机设备。该器件的部分功能包括 I/O 诊断、对冗余系统的支持、数据报和全局数据传输、便携式显示器的连接端口和串行接口端口。在连接到Genius总线的大设备数量下，通信信道速率测量为153.6 kbaud。支持的大总线长度为 7500 英尺;但是，通信速率会随着总线长度的增加而降低。IC687BEM731支持以下总线类型：菊花链、屏蔽双绞线 （STP） 电缆、双芯电缆，可能还有光纤电缆。IC687BEM731可以安装在Genius总线上的任何位置;但是，如果设备放置与编程的设备编号匹配，则性能会提高。总线控制器的设备编号通常为 31。要安装此设备，请关闭机架电源，将控制器牢固地固定到背板上，并连接各种总线连接。若要配置IC687BEM731，请将计算机版逻辑开发人员 5.0 软件与第二个 Service Pack 或更高版本配合使用。注意：Genius总线上的每个设备必须通过编程软件或写入配置COMMREQS单独编程。

The IC687BEM731 is a Genius bus controller manufactured by GE Automation and Control, compatible with the 90-70 series or PACSystems RX7i system. The IC687BEM731 can be connected to up to 31 additional devices on a Genius communication bus. This device occupies a single slot on the PLC backplane. Through the Genius bus, IC687BEM731 is compatible with various types of devices, including Genius I/O modules, various other programmable logic controllers, remote descent of 90-70 series systems, Versamax I/O stations, on-site control stations, and several other host devices that require datagram and global data communication. Some of the functions of this device include I/O diagnosis, support for redundant systems, datagram and global data transmission, connection ports for portable displays, and serial interface ports. With a large number of devices connected to the Genius bus, the communication channel rate is measured at 153.6 kbaud. The supported large bus length is 7500 feet; However, the communication rate will decrease as the bus length increases. IC687BEM731 supports the following bus types: daisy chain, shielded twisted pair (STP) cable, dual core cable, and possibly fiber optic cable. IC687BEM731 can be installed anywhere on the Genius bus; However, if the device placement matches the programmed device number, performance will improve. The device number of the bus controller is usually 31. To install this device, turn off the rack power, securely secure the controller to the backplane, and connect various bus connections. To configure IC687BEM731, please use the computer version of Logic Developer 5.0 software with a second service pack or later. Note: Each device on the Genius bus must be programmed separately through programming software or writing configuration COMMREQS.
