一般信息機(jī)架接口模塊
（RIM）是3300機(jī)架的主要接口。它支持用于配置機(jī)架和檢索機(jī)械信息的Bently Nevada專有協(xié)議。RIM必須位于機(jī)架的插槽1中（靠近電源）。RIM提供支持當(dāng)前Bently Nevada通信處理器（瞬態(tài)數(shù)據(jù)接口外部（TDIX）和動態(tài)數(shù)據(jù)接口外部接口（DDIX））所需的連接。盡管RIM確實提供了整個機(jī)架通用的某些功能，但RIM不是關(guān)鍵監(jiān)控路徑的一部分。RIM的運(yùn)行（或不運(yùn)行）不會影響整個監(jiān)控系統(tǒng)的正常正常運(yùn)行。前視圖后視圖1）LED：指示模塊的運(yùn)行狀態(tài)（參見第2.3節(jié)）2）硬件開關(guān)：（參見第3.2.2節(jié)）3300/20操作和維護(hù)2一般信息3）配置端口：僅使用RS-232協(xié)議從該機(jī)架配置或檢索機(jī)械數(shù)據(jù)。4） 機(jī)架接口I/O模塊：菊花鏈或使用RS-232和RS-422協(xié)議配置機(jī)架（見第4.1節(jié)）5）數(shù)據(jù)管理器I/O模塊：將兩個Bently Nevada通信處理器連接至3300機(jī)架。（參見第4.2節(jié)）RIM功能觸點(diǎn)?機(jī)架復(fù)位?跳閘倍增?報警抑制?OK繼電器安全?密碼?按鍵開關(guān)通信端口?前面板配置端口?后面板主機(jī)端口?后板機(jī)架RS-422端口?數(shù)據(jù)管理器端口事件列表?報警事件列表?系統(tǒng)事件列表2.1 TMR的三模塊冗余（TMR）說明3300系統(tǒng)需要TMR版本的RIM。除所有標(biāo)準(zhǔn)RIM功能外，TMR RIM還執(zhí)行“監(jiān)視器通道比較”。
3300 TMR配置
使用監(jiān)視器選項中指定的設(shè)置執(zhí)行監(jiān)視表決。使用此方法，TMR RIM連續(xù)比較3個冗余監(jiān)視器的指定輸出。如果TMR RIM檢測到其中一個監(jiān)測器的信息不再與其余兩個監(jiān)測器等效（在配置的百分比內(nèi)），則會將監(jiān)測器標(biāo)記為錯誤，并將事件置于系統(tǒng)事件列表中。2.2狀態(tài)機(jī)架接口模塊返回模塊和通道狀態(tài)。本節(jié)描述了可用狀態(tài)及其位置。模塊狀態(tài)正常這表示機(jī)架接口模塊是否正常工作。在以下任何情況下，都會返回不正常狀態(tài)：?模塊中的硬件故障?節(jié)點(diǎn)電壓故障?正常繼電器線圈檢查失敗
General Information Rack Interface Module
(RIM) is the main interface of the 3300 rack. It supports Bently Nevada proprietary protocols for configuring racks and retrieving machinery information. The RIM must be in slot 1 of the rack (near the power supply). RIM provides the connections needed to support current Bently Nevada communication processors (Transient Data Interface External (TDIX) and Dynamic Data Interface External (DDIX)). Although RIM does provide some functions common to the entire rack, RIM is not part of the critical monitoring path. The operation (or non operation) of RIM will not affect the normal operation of the entire monitoring system. Front View Rear View 1) LED: Indicates the operating status of the module (see Section 2.3) 2) Hardware Switches: (see Section 3.2.2) 3300/20 Operation and Maintenance 2 General Information 3) Configuration Ports: Configure or retrieve mechanical data from this rack using RS-232 protocol only. 4) Rack Interface I/O Module: daisy chain or configure the rack using RS-232 and RS-422 protocols (see Section 4.1) 5) Data Manager I/O Module: Connect two Bently Nevada communication processors to the 3300 rack.

Rear panel host port ? Rear panel rack RS-422 port ? Data manager port event list ? Alarm event list ? System event list 2.1 TMR three module redundancy (TMR) description 3300 system requires TMR version of RIM. In addition to all standard RIM functions, the TMR RIM performs a Monitor Channel Comparison.
3300 TMR Configuration
Performs monitoring voting using the settings specified in the Monitor options. Using this method, the TMR RIM continuously compares the specified outputs of three redundant monitors. If the TMR RIM detects that the information of one of the monitors is no longer equivalent to that of the other two monitors (within the configured percentage), it flags the monitor as an error and places the event in the system event list. 2.2 Status The Rack Interface Module returns module and channel status. This section describes the available states and their locations. The module status is OK This indicates whether the Rack Interface Module is working properly. An abnormal state will return under any of the following conditions: ? Hardware failure in the module ? Node voltage failure ? Normal relay coil check failure
