來自接地系統(tǒng)混亂時(shí)的干擾:接地是提高電子設(shè)備電磁兼容性(EMC)的有效手段之一。正確的接地,既能抑制電磁干擾的影響,又能抑制設(shè)備向外發(fā)出干擾;而錯(cuò)誤的接地,反而會(huì)引入嚴(yán)重的干擾信號(hào),使PLC系統(tǒng)將無法正常工作。
來自PLC系統(tǒng)內(nèi)部的干擾:主要由系統(tǒng)內(nèi)部元器件及電路間的相互電磁輻射產(chǎn)生,如邏輯電路
邏輯電路是包含邏輯關(guān)系的數(shù)字電路, 以二進(jìn)制為原理、實(shí)現(xiàn)數(shù)字離散信號(hào)的傳遞,邏輯運(yùn)算和操作的電路。基本的邏輯電路是常見的門電路,而簡(jiǎn)單的門電路為與電路、或電路和非電路。相互輻射及其對(duì)模擬電路的影響,模擬地與邏輯地的相互影響及元器件間的相互不匹配使用等。
