PLC控制系統(tǒng)由于具有功能強(qiáng)、程序設(shè)計(jì)簡(jiǎn)單、擴(kuò)展性好、維護(hù)方便、可靠性高、能適應(yīng)比較惡劣的工業(yè)環(huán)境的特點(diǎn),因此在工業(yè)企業(yè)廣泛應(yīng)用.但是由于工業(yè)環(huán)境條件惡劣,以及各種工業(yè)電磁,輻射干擾等,影響PLC控制系統(tǒng)的正常工作,因此必須重視PLC控制系統(tǒng)的抗干擾設(shè)計(jì).為防止干擾,可以采用硬件和軟件相結(jié)合的抗干擾方法. 防止硬件干擾的方法有:1采用性能優(yōu)良的電源來(lái)抑制電網(wǎng)引入的干擾2電纜的選擇與鋪設(shè)來(lái)降低電磁干擾3完善接地系統(tǒng)4采用光電隔離來(lái)抑制輸入輸出電路引入的干擾等.而利用PLC軟件來(lái)減少干擾是PLC控制系統(tǒng)正常、穩(wěn)定工作的重要環(huán)節(jié)
