HONEYWELL FC-PSU-UNI2450U V1.0卡件,FC-PSU-UNI2450U V1.0實(shí)驗數據
將傳遞不同信號的電纜隔離開(kāi)來(lái)，采用分層鋪設的方式對電纜進(jìn)行一定的調控，從而保證電纜之間不會(huì )相互作用。對于傳遞相同信號的電纜來(lái)說(shuō)，也應當盡可能避免線(xiàn)路密集的糾纏，由于計算機端口在對信號進(jìn)行處理時(shí)對信號可以進(jìn)行一定程度的精密分析，所以如果有較為類(lèi)似的信號互相發(fā)生信號干擾時(shí)，FC-PSU-UNI2450U V1.0會(huì )對計算機的判斷產(chǎn)生影響，從而導致計算機工作過(guò)程中出現分析錯誤。
信號線(xiàn)隔離
在設備運行過(guò)程中，可以采用電纜隔離的方式將信號進(jìn)行隔離，從而保證信號之間不會(huì )產(chǎn)生相互影響。但隔離方式不僅可以將傳輸信號線(xiàn)進(jìn)行隔離，還可以在電腦端將信號進(jìn)行分類(lèi)隔離，采用這種隔離方式可以很大程度上減小共模干擾對計算機造成的危害。還可以采用隔離放大器將信號的輸入端與計算機完全隔離，采用這種方式可以對阻斷干擾信號之間形成回路，抑制干擾的危害，保證系統的正常運行。
供電系統隔離
由于一些現場(chǎng)常常會(huì )對大功率電機進(jìn)行開(kāi)關(guān)，開(kāi)關(guān)過(guò)程中會(huì )產(chǎn)生高頻信號，為了防止高頻電磁對系統產(chǎn)生干擾，可以通過(guò)在供電線(xiàn)路上安裝變壓器，可以對大功率電機開(kāi)關(guān)所產(chǎn)生的高頻電磁進(jìn)行約束，避免對系統產(chǎn)生影響。
扭絞與屏蔽HONEYWELL FC-PSU-UNI2450U V1.0卡件
信號導線(xiàn)的扭絞即雙絞線(xiàn)替代平行導線(xiàn)，可達到抑制磁場(chǎng)干擾效果。
屏蔽即采取金屬導體隔絕元件、組合件以及信號線(xiàn)。屏蔽可以很好的抑制電容性耦合噪聲。常用的方法是通過(guò)屏蔽雙絞線(xiàn)連接模擬信號。通常情況下，不但電噪聲干擾信號，而且強交變磁場(chǎng)也會(huì )干擾信號。因此，不但需要考慮電屏蔽，而且需要考慮磁屏蔽，可以采取導磁性能優(yōu)越(如鐵、鎳等)的導體實(shí)現屏蔽措施。
shutdown functions of the system can be realized to the greatest extent. According to different processes, stone equipment is mainly divided into three categories: stone sawing machine, cutting machine and stone grinding machine. Hollysys LM and Le series PLC have been widely used in three kinds of equipment. At present, the mainstream configuration in the market mostly adopts two sets of PLC to complete the system functions. Because of its high performance, Hollysys recently launched Le products, and only one set of PLC fully meets the system requirements. This paper focuses on the application of Hollysys Le PLC in stone grinding machine equipment, With the continuous improvement of automation, stone equipment is gradually developing in the direction of diversification, high efficiency, precision, automation and assembly line.
In the industrial environment, programmable logic controller (PLC) has become the most widely used core device in
