BENTLY 3500/77M氣缸壓力監測器
本附錄列出了通電特定VMIVME-7740時(shí)發(fā)現的默認值。功能概述第115頁(yè)圖E-1中的框圖說(shuō)明了VMIVME-7740，強調了I/O特性，包括PCI到VMEbus橋。功能塊左上角的圓圈數字引用了功能塊編程所需的適當數據手冊。設備地址定義標準PC/AT架構為CPU板上的設備和外圍設備定義了兩種不同類(lèi)型的地址空間。這些空間通常被命名為內存地址空間和I/O地址空間。這些區域的邊界限于物理上位于CPU板上的地址總線(xiàn)的數量。VMIVME-7740在板上有32條地址總線(xiàn)，從而將地址空間的限制定義為4 Gbyte。
This appendix lists the defaults that are found by powering up a specific VMIVME-7740. Functional Overview The block diagram included in Figure E-1 on page 115 illustrates the VMIVME-7740 emphasizing the I/O features, including the PCI-to-VMEbus bridge. The circled number in the upper left corner of a function block references the appropriate data book necessary for the programming of the function block.Device Address Definition The standard PC/AT architecture defines two distinctive types of address spaces for the devices and peripherals on the CPU board. These spaces have typically been named Memory address space and I/O address space. The boundaries for these areas are limited to the number of address bus lines that are physically located on the CPU board. The VMIVME-7740 has 32 address bus lines located on the board, thereby defining the limit of the address space as 4 Gbyte.
