BENTLY 3500/23E瞬態(tài)數(shù)據(jù)接口PLC模塊
作為參考，以下是一些快速轉(zhuǎn)換公式：段：偏移到線性地址線性地址=（段×16）+偏移到段的線性地址：偏移段=（（線性地址÷65536）?余數(shù)）×4096偏移=余數(shù)×65536其中余數(shù)=（線性地址？65536）的小數(shù)部分請注意，單個(gè)位置有許多可能的段：偏移地址。上面的公式將通過將段強(qiáng)制到偶數(shù)64 KB邊界來提供唯一的段：偏移地址，例如$C00、$E000等。使用此公式時(shí)，確保正確舍入偏移計(jì)算。VMIVME-7740執(zhí)行標(biāo)準(zhǔn)IBM PC/AT主板的所有功能，具有以下功能：?單插槽VMEbus 6U大小?包括高性能Intel Pentium III處理器?高達(dá)512 Mbyte的同步DRAM?64位AGP SVGA視頻圖形加速器—4 Mbyte SGRAM視頻內(nèi)存—分辨率高達(dá)1600x1200x56k色?電池支持的時(shí)鐘/日歷?前面板重置開關(guān)和微型揚(yáng)聲器?鍵盤和鼠標(biāo)、Ultra IDE硬盤驅(qū)動器、軟盤驅(qū)動器、雙以太網(wǎng)、視頻、雙串行和USB的車載端口
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
