詳細內容：MC-PLAM02 網絡構成 AB的DH+局域網最多可掛64個站，通訊速率根據傳輸距離（>300米）與主機型號(PLC-5/40, PLC-5/60)我們選用了57.6K，其網絡拓撲結構為主/支干或雛菊鏈，由于原獨立設備網絡上站點過多且考慮到連接距離的限制(<3048米)，我們將整個網絡整合成三個獨立的DH+局域網，通過AB的1784-KTX(單通道)與1784-KTDX（雙通道）連到上位機服務器上，服務器選用了INTEL的LSDPI服務器，配置為PIII750、18.2GSCSI硬盤、384M ECC內存，Fix32 最多可支持8個通道因此對于系統今后的擴展顯得措措有余。對于各設備分立控制器原屬的局域網在合并后如果發生有站號相同必須作相應調整以防止沖突，而網絡終端電阻亦須作相應調整以適應新網絡的通訊模式。 系統的三個局域網分別包含了如下各獨立車間 A) 原料處理車間，計有煉膠、混合、剝離等 B) 生產車間，記有涂布、烘箱、廢氣處理、卷繞、貼合等 C) 成品車間，記有預檢、防偽、切割、包裝、廢料處理等 HP/Agilent 85990A Multicarrier Signal Generator, 5 to 1100MHz, 75 ohm Tektronix ADA400A, ADA-400A Tektronix ADA400A Differential Preamplifier Boonton 952011 Kit Probe Kit HP/Agilent 54001A Probe 1 GHz For 54100 Series HP/Agilent 10430A 500MHz Probe HP/Agilent 10434A 10:1, 1m Miniature Passive Probe HP/Agilent 1144A 800MHZ Active Probe HP/Agilent 1152A 2.5ghz,0.6pF Active Probe HP/Agilent 11807A -100 HP 8920A/21A RF Communications System Support Test Software HP/Agilent 11807B-044 HP 8921A/D RF Communications System Northern P Series Cell Site Test Software Option 044 Rev.
