最好是把
PLC通電15分鐘（給內(nèi)部電容充電），斷電，在5分鐘內(nèi)換好新的電池，再上電試一下。
西門子PLC有帶卡的，有不帶電池的；也有帶卡的，帶電池的。程序存在MMC卡中，如果沒有存儲(chǔ)卡，需要電池保存程序的，更換電池時(shí)候務(wù)必注意，帶電的情況下，將舊電池取出來，然后將新電池?fù)Q上即可。
編輯本段優(yōu)點(diǎn)
可靠
PLC不需要大量的活動(dòng)元件和連線電子元件。它的連線大大減少。與此同時(shí)，系統(tǒng)的維修簡單，維修時(shí)間短。Plc采用了一系列可靠性設(shè)計(jì)的方法進(jìn)行設(shè)計(jì)。例如：冗余的設(shè)計(jì)。斷電保護(hù)，故障診斷和信息保護(hù)及恢復(fù)。PLC是為工業(yè)生產(chǎn)過程控制而專門設(shè)計(jì)的控制裝置，它具有比通用計(jì)算機(jī)控制更簡單的編程語言和更可靠的硬件。采用了精簡化的編程語言。編程出錯(cuò)率大大降低。廈門潤星貿(mào)易有限公司
