BENTLY 3500/23E瞬态数据接口PLC模块
作为参考，以下是一些快速转换公式：段：偏移到线性地址线性地址=（段×16）+偏移到段的线性地址：偏移段=（（线性地址÷65536）−余数）×4096偏移=余数×65536其中余数=（线性地址？65536）的小数部分请注意，单个位置有许多可能的段：偏移地址。上面的公式将通过将段强制到偶数64 KB边界来提供唯一的段：偏移地址，例如$C00、$E000等。使用此公式时，确保正确舍入偏移计算。VMIVME-7740执行标准IBM PC/AT主板的所有功能，具有以下功能：•单插槽VMEbus 6U大小•包括高性能Intel Pentium III处理器•高达512 Mbyte的同步DRAM•64位AGP SVGA视频图形加速器—4 Mbyte SGRAM视频内存—分辨率高达1600x1200x56k色•电池支持的时钟/日历•前面板重置开关和微型扬声器•键盘和鼠标、Ultra IDE硬盘驱动器、软盘驱动器、双以太网、视频、双串行和USB的车载端口
For reference, here are some quick conversion formulas: Segment:Offset to Linear Address Linear Address = (Segment × 16) + Offset Linear Address to Segment:Offset Segment = ((Linear Address ÷ 65536) − remainder) × 4096 Offset = remainder × 65536 Where remainder = the fractional part of (Linear Address ÷ 65536) Note that there are many possible segment:offset addresses for a single location. The formula above will provide a unique segment:offset address by forcing the segment to an even 64 Kbyte boundary, for example, $C000, $E000, etc. When using this formula, make sure to round the offset calculation properly.The VMIVME-7740 performs all the functions of a standard IBM PC/AT motherboard with the following features: • Single-slot VMEbus 6U size • Includes a high-performance Intel Pentium III processor • Up to 512 Mbyte of Synchronous DRAM • 64-bit AGP SVGA video graphics accelerator - 4 Mbyte SGRAM Video Memory - Resolutions up to 1600x1200x56k colors • Battery-backed clock/calendar • Front panel reset switch and miniature speaker • On-board port for a keyboard and mouse, Ultra-IDE hard drive, floppy drive, dual Ethernet, video, dual serial, and USB
