IC687RCM711B  冗余通信模块  用于连接总线发送模块

型号：IC687RCM711B

IC687RCM711B是一个冗余通信模块，它为从主设备到备份设备的同步消息提供了一条路径。然后，这被用作在FIP单机架冗余系统中同步双cpu的方法。这也允许在两个单元之间传输共享I/O数据的路径。FIP单机架冗余系统的单元之间的实际物理连接可以包含多达三英尺的总互连电缆。兼容的cpu包括IC697CFR782和IC697CFR28。

IC687RCM711B冗余通信模块在机架上占用一个槽位，包含两个连接器。上面的连接器用于连接总线发送模块，而下面的连接器则不用于此目的。有5个绿色led显示RCM模块的健康状态指示。同时监控热备CPU冗余系统的控制状态。

该模块还提供了一个按钮，允许用户手动切换控制从活动到备用单元。这只有在备份单元准备好使用时才有效。这允许用户在系统仍然在线的情况下维护以前活跃的单元。角色切换完成后，至少需要10秒才能完成新的切换。该RCM必须通过Windows编程或MS-DOS软件配置到FIP冗余系统中。该设备需要5V总线，有效数据速率为500kbytes / s。

Model: IC687RCM711B

The IC687RCM711B is a redundant communication module that provides a path for synchronous messages from the primary device to the backup device. This was then used as a method to synchronize dual cpus in a FIP single-stand redundant system. This also allows the path of shared I/O data to be transferred between the two cells. The actual physical connection between the units of a FIP single-stand redundant system can contain up to three feet of total interconnection cable. Compatible cpus include IC697CFR782 and IC697CFR28.

The IC687RCM711B redundant communication module occupies one slot in the rack and contains two connectors. The upper connector is used to connect the bus sending module, while the lower connector is not used for this purpose. There are 5 green leds that show the health status indicator of the RCM module. In addition, monitor the control status of the hot spare CPU redundancy system.

The module also provides a button that allows the user to manually switch control from the active to the standby unit. This only works when the backup unit is ready for use. This allows users to maintain previously active units while the system is still online. After the role switch is complete, it will take at least 10 seconds to complete the new switch. This RCM must be configured into a FIP redundant system either through Windows programming or MS-DOS software. The device requires a 5V bus with an effective data rate of 500kbytes/s.
