當SF繼續運行(xing)S7-300PLC并使BF指示燈閃爍時，這(zhe)絕對是分布在域總線或DP從(cong)站的PROFIBUS-DP總線的問題，例如變頻(pin)器，設備，DCS或DP/DP西門子S7-1500CPU主機啟動狀態燈都不亮維修，以通(tong)過PROFIBUS-DP與CPU通(tong)信。 耦合和其他現(xian)場機(ji)器存在問題(ti)，此(ci)時我們需(xu)要檢查硬件物理(li)層(ceng)是否已(yi)成(cheng)功完成(cheng)通(tong)訊(xun)(xun)，若物理(li)層(ceng)通(tong)訊(xun)(xun)成(cheng)功，則需(xu)要查看相關(guan)通(tong)訊(xun)(xun)的通(tong)訊(xun)(xun)數據以及通(tong)訊(xun)(xun)類型是否正(zheng)確，如通(tong)訊(xun)(xun)報文，通(tong)訊(xun)(xun)波特率，通(tong)訊(xun)(xun)硬件DP地址等(deng)。
