各位工控好友：
              你們好，昨天我廠(chǎng)一臺結晶機由于外部一傳感器短路造成一Fx2n-80mrPLC電源模塊冒煙燒壞。我隨及找到一塊與之匹配的電源塊，更換后通電，PROG-E燈在閃爍，我清除了內存后，重新下載了新程序，PLC還是經(jīng)常出現PROG-E燈閃爍的現象，請問(wèn)各位大俠，這到底是哪里的問(wèn)題？PLC硬件會(huì )不會(huì )有問(wèn)題？謝謝！

如果你已經(jīng)清除過(guò)PLC，并且寫(xiě)個(gè)簡(jiǎn)單程序去測試一下PLC，而PLC仍然報PROG-E燈閃爍，那PLC損壞的可能性就很大了，
