plc能輸入開關(guān)量，也就是一高一低的電平電壓，而編碼器脈沖信號，可以理解一定時間內(nèi)，用極快的速度完成的一組開關(guān)量。但是因為這種開關(guān)量的頻率太高了，所以PLC的普通I/O口是無法準(zhǔn)確讀到這些脈沖的個數(shù)的，因為PLC工作過程中存在掃描周期，需要每個一段時間才去刷新一下普通I/O口的數(shù)據(jù)，而編碼器的精度太高了，單位時間內(nèi)輸出的脈沖個數(shù)太多，普通I/O是無法勝任的。一般PLC會設(shè)計有高速計數(shù)端口，本質(zhì)是利用了底層單片機的硬件邏輯來完成這些編碼器計數(shù)的，避開了掃描周期問題，PLC都設(shè)計有專門的高速計數(shù)指令，使用的時候，直接調(diào)用這些指令就可以讀到當(dāng)前的脈沖值了。

屏蔽對與屏蔽對具有較好的絕緣性能，電纜在使用中若屏蔽對屏蔽對之間出現(xiàn)電位差時，不會影響信號的傳輸質(zhì)量。用于以電子計算機為主的自動控制系統(tǒng),尤其適用于計算機集散控制系統(tǒng),傳遞生產(chǎn)裝置過程變量的檢測、控制、聯(lián)鎖、報警等模擬和數(shù)字信號。
RS485 wiring can be arbitrary layout into star connection withtree, 485 wiring specification is the wiring must be hand in hand,when there is no use 485 hub and 485 relay setting directly intothe star connection and connection in a tree, it is easy to causereflection bus no. Many contractor in 485 wiring, use of starconnection and tree, sometimes the very, but sometimes is alwaysappear problem, and it is difficult to find the reason, is usuallycaused by non-standard wiring. If star connection or treeconnection is required due to field connection, the 485 hub and 485relay of shenzhen fuyongtong technology co., LTD can be used tosolve related problems.
此結(jié)構(gòu)的屏蔽電纜可抗電磁感應(yīng)、接地不良和電源線傳導(dǎo)干擾，減小電感，防止感應(yīng)電動勢過大。屏蔽層既起到抑制電磁波對外發(fā)射的作用，又可作為短路電流的通道，能起到中性線芯的保護(hù)作用。6／10kV變頻電機專用電纜，考慮到電纜在使用過程中經(jīng)常受到徑向外力作用，在電纜屏蔽層外增加鍍鋅鋼帶鎧裝層（在屏蔽層和鋼帶鎧裝層之間加隔離套）。

???? In flame retardant series products, has been successfully usedin the oxygen isolation technology, not only 0.6/1 kv polyvinylchloride insulated and crosslinked polyethylene insulation flameretardant power cable can achieve GB/T12666.5 "into A bunch ofpower cable test" in class A, and rated voltage up to and including6/10 kv 8.7/15 kv crosslinked poly (flame retardant power cable canreach A high class A demand and A large margin. On the basis ofhigh flame retardant and high flame retardant cross-linkedinsulation, a low-smoke halogen-free high-flame retardant oxygeninsulation layer power cable was added, and its low-smokehalogen-free performance was in line with GB/T17651.1.2 and GB/t1765650.1.2. In this way, the overall level of the company'scross-linked power cable is lower than the domestic status. Thiscompany produces the type refractory power cables for rated voltage0.6/1 kv copper core cable, can also produce low smoke zero halogenfire-resistant power cable, high flame retardant fire-resistantpower cable oxygen insulation layer, the fire-resistant performancein line with the GB/T12666.6 cable fire resistance test. Therefore,the overall performance of refractory series power cables is goodand reliable. The water resistance performance of fireproof cableconforms to iec 502-2.
