EMERSON KJ3202X1-BA1渦流傳感器及前置器
前面板MVME7100前面板上提供以下開(kāi)關(guān)、LED和連接器。每個(gè)復位/中止開(kāi)關(guān)的位置見(jiàn)圖3-1。MVME7100有一個(gè)按鈕開(kāi)關(guān)，可提供中止和復位功能。當開(kāi)關(guān)按下少于3秒時(shí)，MC8641D PIC會(huì )產(chǎn)生一個(gè)中止中斷。如果開(kāi)關(guān)保持超過(guò)3秒，則會(huì )生成板硬復位。如果MVME7100是VMEbus系統控制器，則會(huì )生成VME SYSRESET。LED下表描述了MVME71000前面板上的LED。有關(guān)LED位置，請參閱第47頁(yè)圖3-1。BFL板故障前面板紅色。此指示燈在硬復位期間點(diǎn)亮，并保持點(diǎn)亮，直到軟件將其關(guān)閉。LED由Tsi148中VSTAT寄存器的第14位（BDFAIL）控制。USR1用戶(hù)定義前面板紅色/黃色此指示燈由狀態(tài)指示器寄存器中相應寄存器位的S/W斷言點(diǎn)亮。有關(guān)詳細信息，請參閱《程序員指南》。
Front Panel The following switch, LEDs, and connectors are available on the MVME7100 front panel. Refer to Figure 3-1 for the location of each.Reset/Abort Switch The MVME7100 has a single push button switch to provide both the abort and reset functions. When the switch is depressed for less than 3 seconds, an abort interrupt is generated to the MC8641D PIC. If the switch is held for more than 3 seconds, a board hard reset is generated. If the MVME7100 is the VMEbus system controller, a VME SYSRESET is generated.LEDs The next table describes the LEDs on the front panel of the MVME7100. Refer to Figure 3- 1 on page 47 for LED locations.BFL Board Fail Front panel Red This indicator is illuminated during a hard reset and remains illuminated until software turns it off. The LED is controlled by bit 14 (BDFAIL) of the VSTAT register in the Tsi148. USR1 User Defined Front panel Red/Yellow This indicator is illuminated by S/W assertion of its corresponding register bits in the Status Indicator Register. See the Programmer's Guide for further detail.
