只要M301~M349其中有一點動作，M300就ON，这个感觉容易做到；
直接M300從去找異常點的程式在那，这个有些不太明白，M300如何与故障点的程序连接，能否再详细点说明了。

把異常集中在一點，是方便你對PLC程式除錯。
vb程式可以對你設定的異常點區域作搜尋比對，只要其中一個點=on，就是有異常。
底下部份程式給你參考看看。設一個time去掃程式。

Private Sub tmrAlarm_Timer()
  Dim I As Integer
  Dim J As Integer
  Dim sDATA(100) As String
  Dim mData(100) As Integer

  '讀取M值狀態
  sDATA(0) = ReadM(300)
  gf = PLC.ReadDeviceRandom2(sDATA(0), CLng(10), mData(0))
  sDATA(1) = ReadM(310)
  gf = PLC.ReadDeviceRandom2(sDATA(1), CLng(10), mData(10))
  sDATA(2) = ReadM(320)
  gf = PLC.ReadDeviceRandom2(sDATA(2), CLng(10), mData(20))
  sDATA(3) = ReadM(330)
  gf = PLC.ReadDeviceRandom2(sDATA(3), CLng(10), mData(30))
  sDATA(4) = ReadM(340)
  gf = PLC.ReadDeviceRandom2(sDATA(4), CLng(10), mData(40))
  sDATA(5) = ReadM(350)
  gf = PLC.ReadDeviceRandom2(sDATA(5), CLng(10), mData(50))
  sDATA(6) = ReadM(360)
  gf = PLC.ReadDeviceRandom2(sDATA(6), CLng(10), mData(60))
  sDATA(6) = ReadM(370)
  gf = PLC.ReadDeviceRandom2(sDATA(7), CLng(10), mData(70))
  sDATA(8) = ReadM(380)
  gf = PLC.ReadDeviceRandom2(sDATA(8), CLng(10), mData(80))

  For N = 0 To 9
      M(300 + N) = mData(N)
      M(310 + N) = mData(N + 10)
      M(320 + N) = mData(N + 20)
      M(330 + N) = mData(N + 30)
      M(340 + N) = mData(N + 40)
      M(350 + N) = mData(N + 50)
      M(360 + N) = mData(N + 60)
      M(370 + N) = mData(N + 70)
      M(380 + N) = mData(N + 80)
  Next N

谢你

谢谢 litung  ，我要续好好学习。
litung 你好，我在使用中出现如图所示问题。

感谢分享，正好下来学习学习。

READ()程式我沒放上來。
只是給部份程式讓你參考而己。

程式如下：
Public Function ReadM(NO As String)
  Dim sDATA As String
  Select Case NO
    Case 300:
      sDATA = "M300" & Chr(10) & "M301" & Chr(10) & "M302" & Chr(10) & "M303" & Chr(10) & "M304" & Chr(10) & "M305" & Chr(10) & "M306" & Chr(10) & "M307" & Chr(10) & "M308" & Chr(10) & "M309" & Chr(10)
    Case 310:
      sDATA = "M310" & Chr(10) & "M311" & Chr(10) & "M312" & Chr(10) & "M313" & Chr(10) & "M314" & Chr(10) & "M315" & Chr(10) & "M316" & Chr(10) & "M317" & Chr(10) & "M318" & Chr(10) & "M319" & Chr(10)
    Case 320:
      sDATA = "M320" & Chr(10) & "M321" & Chr(10) & "M322" & Chr(10) & "M323" & Chr(10) & "M324" & Chr(10) & "M325" & Chr(10) & "M326" & Chr(10) & "M327" & Chr(10) & "M328" & Chr(10) & "M329" & Chr(10)
    Case 330:
      sDATA = "M330" & Chr(10) & "M331" & Chr(10) & "M332" & Chr(10) & "M333" & Chr(10) & "M334" & Chr(10) & "M335" & Chr(10) & "M336" & Chr(10) & "M337" & Chr(10) & "M338" & Chr(10) & "M339" & Chr(10)
    Case 340:
      sDATA = "M340" & Chr(10) & "M341" & Chr(10) & "M342" & Chr(10) & "M343" & Chr(10) & "M344" & Chr(10) & "M345" & Chr(10) & "M346" & Chr(10) & "M347" & Chr(10) & "M348" & Chr(10) & "M349" & Chr(10)
    Case 350:
      sDATA = "M350" & Chr(10) & "M351" & Chr(10) & "M352" & Chr(10) & "M353" & Chr(10) & "M354" & Chr(10) & "M355" & Chr(10) & "M356" & Chr(10) & "M357" & Chr(10) & "M358" & Chr(10) & "M359" & Chr(10)
    Case 360:
      sDATA = "M360" & Chr(10) & "M361" & Chr(10) & "M362" & Chr(10) & "M363" & Chr(10) & "M364" & Chr(10) & "M365" & Chr(10) & "M366" & Chr(10) & "M367" & Chr(10) & "M368" & Chr(10) & "M369" & Chr(10)
    Case 370:
      sDATA = "M370" & Chr(10) & "M371" & Chr(10) & "M372" & Chr(10) & "M373" & Chr(10) & "M374" & Chr(10) & "M375" & Chr(10) & "M376" & Chr(10) & "M377" & Chr(10) & "M378" & Chr(10) & "M379" & Chr(10)
    Case 380:
      sDATA = "M380" & Chr(10) & "M381" & Chr(10) & "M382" & Chr(10) & "M383" & Chr(10) & "M384" & Chr(10) & "M385" & Chr(10) & "M386" & Chr(10) & "M387" & Chr(10) & "M388" & Chr(10) & "M389" & Chr(10)
  End Select
  ReadM = sDATA
End Function

有空你再自己簡化那二段程式。

好的，谢谢你。

litung你好，你能把这个发上来吗？谢谢了。

我下载运行时出错，请高手指教。请看附件截图。
