HONEYWELL FC-PSU-UNI2450U V1.0卡件,FC-PSU-UNI2450U V1.0實(shí)驗(yàn)數(shù)據(jù)
將傳遞不同信號(hào)的電纜隔離開(kāi)來(lái)，采用分層鋪設(shè)的方式對(duì)電纜進(jìn)行一定的調(diào)控，從而保證電纜之間不會(huì)相互作用。對(duì)于傳遞相同信號(hào)的電纜來(lái)說(shuō)，也應(yīng)當(dāng)盡可能避免線路密集的糾纏，由于計(jì)算機(jī)端口在對(duì)信號(hào)進(jìn)行處理時(shí)對(duì)信號(hào)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(hào)互相發(fā)生信號(hào)干擾時(shí)，F(xiàn)C-PSU-UNI2450U V1.0會(huì)對(duì)計(jì)算機(jī)的判斷產(chǎn)生影響，從而導(dǎo)致計(jì)算機(jī)工作過(guò)程中出現(xiàn)分析錯(cuò)誤。
信號(hào)線隔離
在設(shè)備運(yùn)行過(guò)程中，可以采用電纜隔離的方式將信號(hào)進(jìn)行隔離，從而保證信號(hào)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(hào)線進(jìn)行隔離，還可以在電腦端將信號(hào)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(duì)計(jì)算機(jī)造成的危害。還可以采用隔離放大器將信號(hào)的輸入端與計(jì)算機(jī)完全隔離，采用這種方式可以對(duì)阻斷干擾信號(hào)之間形成回路，抑制干擾的危害，保證系統(tǒng)的正常運(yùn)行。
供電系統(tǒng)隔離
由于一些現(xiàn)場(chǎng)常常會(huì)對(duì)大功率電機(jī)進(jìn)行開(kāi)關(guān)，開(kāi)關(guān)過(guò)程中會(huì)產(chǎn)生高頻信號(hào)，為了防止高頻電磁對(duì)系統(tǒng)產(chǎn)生干擾，可以通過(guò)在供電線路上安裝變壓器，可以對(duì)大功率電機(jī)開(kāi)關(guān)所產(chǎn)生的高頻電磁進(jìn)行約束，避免對(duì)系統(tǒng)產(chǎn)生影響。
扭絞與屏蔽HONEYWELL FC-PSU-UNI2450U V1.0卡件
信號(hào)導(dǎo)線的扭絞即雙絞線替代平行導(dǎo)線，可達(dá)到抑制磁場(chǎng)干擾效果。
屏蔽即采取金屬導(dǎo)體隔絕元件、組合件以及信號(hào)線。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)屏蔽雙絞線連接模擬信號(hào)。通常情況下，不但電噪聲干擾信號(hào)，而且強(qiáng)交變磁場(chǎng)也會(huì)干擾信號(hào)。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(dǎo)磁性能優(yōu)越(如鐵、鎳等)的導(dǎo)體實(shí)現(xiàn)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
