VMIVME-3122通用電氣卡件角色切換狀態(tài)被反跳并過濾,以防止意外激活。當(dāng)RMX模塊用作通用反射存儲器網(wǎng)絡(luò)中的節(jié)點時(即不用作冗余鏈路),角色切換對模塊操作沒有影響。光收發(fā)器

光收發(fā)器有兩個“LC”型光纖端口。標(biāo)有“TX”的端口是發(fā)射器和端口標(biāo)有“RX”的是接收器。內(nèi)存交換模塊使用單工(單光纖)或雙工(雙光纖)聯(lián)網(wǎng)在一起多模光纖電纜。具體的電纜結(jié)構(gòu)取決于您的操作環(huán)境。對于有關(guān)光纖電纜的詳細(xì)信息,請參閱PACSystems RX7i Memory Xchange Modules用戶手冊,GFK-2300.安裝在開始之前,請確保您有以下列出的項目。

■ 具有2.00版或更高版本固件的PACSystems RX7i CPU

■ 帶電源的PACSystems Rx7i CPU機(jī)架。

■ 編程軟件:Machine Edition–Logic Developer PLC,4.5或更高版本(和PC兼容計算機(jī))。

■ 電纜。有關(guān)詳細(xì)信息,請參閱PACSystems RX7i Memory Xchange中的“光纜和連接器”

模塊用戶手冊,GFK-2300。注:包含一個或多個內(nèi)存交換模塊的RX7i系統(tǒng)必須安裝在金屬中帶導(dǎo)管或等效物的外殼,以滿足輻射發(fā)射標(biāo)準(zhǔn)。有關(guān)詳細(xì)信息,請參閱PACSystems RX7i安裝手冊,GFK-2223。

The front panel of the RMX module has eight LED indicators, a toggle switch that can be used to manually 

request a role switch, and an optical transceiver. 

Role Switch 

The Role switch is a spring loaded two-position switch that rests in the OFF state. When the RMX module is 

being used as a redundancy link, this switch allows you to manually switch control from the active controller to 

the backup controller. To initiate the switching of roles, lift the switch to the ON position for at least 1 second. 

The role switch state is de-bounced and filtered to prevent accidental activation. 

When the RMX module is used as a node in a general-purpose reflective memory network (i.e. not used as a 

redundancy link), the Role switch has no effect on module operation. 

Optical Transceiver 

The optical transceiver has two “LC” type fiber optic ports. The port labeled “TX” is the transmitter and the port 

labeled “RX” is the receiver. 

Memory Xchange modules are networked together using either simplex (single fiber) or duplex (dual fiber) 

multimode fiber optic cables. The specific cable construction depends on your operating environment. For 

details on fiber optic cables, refer to the PACSystems RX7i Memory Xchange Modules User’s Manual, GFK-

2300.Installation 

Make sure you have the items listed below before you begin. 

■ A PACSystems RX7i CPU with release 2.00 or higher firmware 

■ A PACSystems Rx7i CPU rack with power supply. 

■ Programming software: Machine Edition – Logic Developer PLC, version 4.5 or later (and a PCcompatible computer). 

■ Cables. For details, see “Fiber optic Cables and Connectors” in the PACSystems RX7i Memory Xchange 

Modules User’s Manual, GFK-2300. 

Note: RX7i systems that include one or more Memory Xchange modules must be installed in a metal 

enclosure with conduit or equivalent to meet radiated emission standards. For details, refer to the 

PACSystems RX7i Installation Manual, GFK-2223.
