西門子(zi)s71500代理 CPU上的開關必須撥在(zai)RUN狀態，否則PLC中的modbus通(tong)(tong)訊(xun)程序沒(mei)有(you)處(chu)于(yu)運行狀態，組(zu)態王和設(she)備通(tong)(tong)過自由(you)口(kou)協議肯定通(tong)(tong)訊(xun)失敗(bai)，(七)S7300MPI電纜方式(shi)是否支持(chi)通(tong)(tong)過GPRS和組(zu)態王通(tong)(tong)訊(xun)，不支持(chi)，組(zu)態王的GPRS通(tong)(tong)訊(xun)方式(shi)要求必須創建虛擬串口(kou)并(bing)通(tong)(tong)過此串口(kou)進行數據通(tong)(tong)訊(xun)。
例如通(tong)(tong)過PLC和(he)變(bian)頻(pin)器建立MODBUS協(xie)議來控制變(bian)頻(pin)器。在網(wang)絡(luo)中有(you)時候有(you)些產品通(tong)(tong)訊協(xie)議非(fei)標準，這是就(jiu)要(yao)用到自由通(tong)(tong)訊了(le)，相當(dang)的靈活(huo)，但要(yao)一定的計算機網(wang)絡(luo)基礎。西門子plcsf紅(hong)燈西門子CPU1517-3三個指示燈都不亮原因分析亮(liang)故障(zhang)原因(yin)分析西門(men)子plcsf紅燈(deng)(deng)亮(liang)故障(zhang)原因(yin)分析西門(men)子PLC上(shang)面(mian)的SF燈(deng)(deng)紅亮(liang)時(shi)表示系(xi)統故障(zhang)。是英文（SYSTEMFAULT)的縮寫(xie)，內部尋(xun)址錯誤，超出(chu)編程地址區，模(mo)塊損壞(huai)，插(cha)件松動等(deng)原因(yin)引起。把PLC里的程序(xu)先清除(chu)掉(diao)，SF燈(deng)(deng)還亮(liang)估計就是硬件壞(huai)了，如(ru)果不亮(liang)了，就可能你的程序(xu)有問題，再在(zai)線(xian)看看PLC信息S7-300PLC上(shang)SF燈(deng)(deng)亮(liang)而BF燈(deng)(deng)閃爍，肯定是分布式現場總(zong)線(xian)PROFIBUS-DP通信或DP從站如(ru)ABB變頻器的問題，不要懷疑其他軟硬件問。
