说明机架接口模块
（RIM）是3500机架的主要接口。它支持用于配置机架和检索机器信息的专有协议。RIM必须位于机架的插槽1中（靠近电源）。RIM支持兼容的Bently Nevada外部通信处理器，如TDXnet、TDIX和DDIX。虽然RIM提供了整个机架通用的某些功能，但RIM不是关键监控路径的一部分，不会影响整个监控系统的正常正常运行。每个机架需要一个RIM。对于三模冗余（TMR）应用，3500系统需要TMR版本的RIM。除所有标准RIM功能外，TMR RIM还执行“监视器通道比较”。3500 TMR配置使用监视器选项中指定的设置实现监视器表决。使用此方法，TMR RIM连续比较三（3）个冗余监视器的输出。如果TMR RIM检测到其中一个监测器的信息不再在其他两个监测器信息的配置百分比内，它将标记监测器出错，并将事件置于系统事件列表中。规格和订购信息零件号141531-01版本A（03/07）第2页，共8页规格输入功耗4.75瓦，典型数据前面板标准RS232串行通信数据速率38.4 k波特。I/O模块标准RS232/RS422串行通信内部调制解调器通信数据速率最大38.4 k波特，串行通信14.4 k波特、内部调制解调器通信。输出前面板LED正常LED指示RIM正常工作。TX/RX LED指示RIM何时与3500机架中的其他模块通信。
有效配置
TM LED指示3500机架处于跳闸倍增状态。CONFIG OK LED指示3500机架具有有效配置。I/O模块OK（正常）继电器，用于指示3500机架何时正常运行或机架内检测到故障。用户可以选择“打开”或“关闭”触点来通知NOT OK状态。该继电器始终在“正常通电”状态下工作。OK继电器额定值为5A@24 Vdc/120 Vac，120瓦/600 VA开关电源。提供常闭触点电弧抑制器。控制前面板机架复位按钮清除机架中的锁定报警和定时OK通道失效。执行与I/O模块上的“机架复位”触点相同的功能。地址开关用于设置机架地址；63个可能的地址。配置键锁用于将3500机架置于“运行”模式或“编程”模式。运行模式允许机架正常运行并锁定配置更改。编程模式允许机架正常运行，也允许本地或远程机架配置。钥匙可以在任一位置从机架上取下，使开关保持在运行或编程位置。将开关锁定在RUN（运行）位置允许您限制未经授权的机架重新配置。将开关锁定在PROGRAM（编程）位置允许随时远程配置机架。
Description Rack Interface Module
(RIM) is the main interface of the 3500 rack. It supports proprietary protocols for configuring racks and retrieving machine information. The RIM must be in slot 1 of the rack (near the power supply). RIM supports compatible Bently Nevada external communication processors such as TDXnet, TDIX, and DDIX. Although RIM provides some functions common to the entire rack, it is not part of the critical monitoring path and will not affect the normal operation of the entire monitoring system. Each rack requires one RIM. For the third mock examination Redundancy (TMR) applications, the 3500 system requires a TMR version of the RIM. In addition to all standard RIM functions, the TMR RIM performs a Monitor Channel Comparison. The 3500 TMR configuration uses the settings specified in the Monitor Options to achieve monitor voting. Using this method, the TMR RIM continuously compares the outputs of three (3) redundant monitors. If the TMR RIM detects that the information for one of the monitors is no longer within the configured percentage of the information for the other two monitors, it flags the monitor error and places the event in the system event list. Specifications and Ordering Information Part No. 141531-01 Rev. A (03/07) Page 2 of 8 Specifications Input Power Consumption 4.75 Watts, Typical Data Front Panel Standard RS232 Serial Communication Data Rate 38.4 kbaud. I/O module standard RS232/RS422 serial communication internal modem communication data rate is 38.4 k baud at most, and 14.4 k baud for serial communication and internal modem communication. The output front panel LED indicates that the RIM is working normally. The TX/RX LED indicates when the RIM is communicating with other modules in the 3500 rack.
Valid configuration
The TM LED indicates that the 3500 rack is in Trip Multiply. The CONFIG OK LED indicates that the 3500 rack has a valid configuration. The I/O module OK relay is used to indicate when the 3500 rack is operating normally or a fault is detected in the rack. The user can select "open" or "close" contacts to notify the NOT OK status. The relay always operates in the "normally energized" state. The OK relay is rated as 5A@24 Vdc/120 Vac, 120W/600 VA switching power supply. A normally closed contact arc suppressor is provided. The control front panel rack reset button clears the lock alarm and timed OK channel failure in the rack. Performs the same function as the Rack Reset contact on the I/O module. The address switch is used to set the rack address; 63 possible addresses. The Configuration Keylock is used to place the 3500 rack in either the Run mode or the Program mode. The operating mode allows the rack to operate normally and lock configuration changes. The programming mode allows the rack to operate normally and also allows local or remote rack configuration. The key can be removed from the rack at any position to keep the switch in the run or programmed position. Locking the switch in the RUN position allows you to limit unauthorized rack reconfiguration. Locking the switch in the PROGRAM position allows the rack to be remotely configured at any time.
