描述

825-MCM20

PLC是一種用于工業(yè)生產自動化控制的設備，一般不需要采取什么措施，就可以直接在工業(yè)環(huán)境中使用。然而，盡管有如上所述的可靠性較高，抗干擾能力較強，但當生產環(huán)境過于惡劣，電磁干擾特別強烈，或安裝使用不當，就可能造成程序錯誤或運算錯誤，從而產生誤輸入并引起誤輸出，這將會造成設備的失控和誤動作，從而不能保證PLC的正常運行，要提高PLC控制系統(tǒng)可靠性，一方面要求PLC生產廠家提高設備的抗干擾能力；另一方面，要求設計、安裝和使用維護中引起高度重視，多方配合才能完善解決問題，有效地增強系統(tǒng)的抗干擾性能。因此在使用中應注意以下問題：

? ? 1．工作環(huán)境

? ? (1)溫度PLC要求環(huán)境溫度在0~55oC，安裝時不能放在發(fā)熱量大的元件下面，四周通風散熱的空間應足夠大。

? ? (2)濕度為了保證PLC的絕緣性能，空氣的相對濕度應小于85%（無凝露）。

? ? (3)震動應使PLC遠離強烈的震動源，防止振動頻率為10~55Hz的頻繁或連續(xù)振動。當使用環(huán)境不可避免震動時，必須采取減震措施，如采用減震膠等。

? ? (4)空氣避免有腐蝕和易燃的氣體，例如氯化氫、硫化氫等。對于空氣中有較多粉塵或腐蝕性氣體的環(huán)境，可將PLC安裝在封閉性較好的控制室或控制柜中。

? ? (5)電源PLC對于電源線帶來的干擾具有一定的抵制能力。在可靠性要求很高或電源干擾特別嚴重的環(huán)境中，可以安裝一臺帶屏蔽層的隔離變壓器，以減少設備與地之間的干擾。一般PLC都有直流24V輸出提供給輸入端，當輸入端使用外接直流電源時，應選用直流穩(wěn)壓電源。因為普通的整流濾波電源，由于紋波的影響，容易使PLC接收到錯誤信息。
