在選擇設(shè)備時(shí)，首先要選擇有較高抗干擾能力的產(chǎn)品，其包括了電磁兼容性（EMC），尤其是抗外部干擾能力，如采用浮地技術(shù)、隔離性能好的PLC系統(tǒng)；其次還應(yīng)了解生產(chǎn)廠(chǎng)給出的抗干擾指標(biāo)，如共模擬制比、差模擬制比，耐壓能力、允許在多大電場(chǎng)強(qiáng)度和多高頻率的磁場(chǎng)強(qiáng)度環(huán)境中工作；另外是靠考查其在類(lèi)似工作中的應(yīng)用實(shí)績(jī)。在選擇國(guó)外進(jìn)口產(chǎn)品要注意：我國(guó)是采用220V高內(nèi)阻電網(wǎng)制式，而歐美地區(qū)是110V低內(nèi)阻電網(wǎng)。由于我國(guó)電網(wǎng)內(nèi)阻大，零點(diǎn)電位漂移大，地電位變化大，工業(yè)企業(yè)現(xiàn)場(chǎng)的電磁干擾至少要比歐美地區(qū)高4倍以上，對(duì)系統(tǒng)抗干擾性能要求更高，在國(guó)外能正常工作的PLC產(chǎn)品在國(guó)內(nèi)工業(yè)就不能可靠運(yùn)行，這就要在采用國(guó)外產(chǎn)品時(shí)，按我國(guó)的標(biāo)準(zhǔn)（GB/T13926）合理選擇。


2綜合抗干擾設(shè)計(jì)
主要考慮來(lái)自系統(tǒng)外部的幾種如果措施。主要內(nèi)容包括：對(duì)PLC系統(tǒng)及外引線(xiàn)進(jìn)行以防空間輻射電磁干擾；對(duì)外引線(xiàn)進(jìn)行隔離、濾波，特別是原理動(dòng)力電纜，分層布置，以防通過(guò)外引線(xiàn)引入傳導(dǎo)電磁干擾；正確設(shè)計(jì)接地點(diǎn)和接地裝置，完善接地系統(tǒng)。另外還利用軟件手段，進(jìn)一步提高系統(tǒng)的安全可靠性。
