I have a file with many groups.in each group there is a time channel.I only want to import a time channel from Groupe, in which there is a channel named Eng_Spd, into Excel.Can someone help me, how should I write the code.Below is my code

Dim oExcel,oWBook,oSheet,K,L,oGroup,lCol,oChn,DisplayType,Sfile
Set oExcel = CreateObject("Excel.Application") ' Excel öffnen
oExcel.Visible = True
Call oExcel.Workbooks.Open("N:\01_IMO-Light\Test\DIAdem-Test.xlsx")
Set oWBook = oExcel.Activeworkbook

If ( 1 < oWBook.Sheets.Count ) Then ' wir wollen nur eine Sheet !
For K = 1 To oWBook.Sheets.Count-1
Call oWBook.Sheets(1).Delete
Next
End If
Set oSheet = oWBook.Sheets(1)
oSheet.Name = "DIAdem_Export"
lCol = 1
For K = 1 To Data.Root.ChannelGroups.Count 'KanalGruppen werden gezählt.
Set oGroup = Data.Root.ChannelGroups(K) 'oGroup ist die KanalGruppe
For L = 1 To oGroup.Channels.Count
Set oChn = oGroup.Channels(L) 'oChn ist die Nummer von Kanälen

if oChn.Name = "time" or oChn.Name = "Eng_Spd" or oChn.Name = "Eng_Trq" or oChn.Name = "Eng_Trq_indicated" or oChn.Name = "InjCrv_qSetUnBal" or oChn.Name ="Veh_Spd" then
oSheet.Cells(1,lCol) = oChn.Name 'Die bestimmten Messdaten in Excel übernehmen
oSheet.Cells(2,lCol) = oGroup.Name
oSheet.Cells(3,lCol) = oChn.Properties("unit_string").Value
Call ChannelToExcelColumnBlk(oChn,oExcel,oSheet,lCol,4) '
lCol = lCol + 1
Else
End if
Next
Next

Dim lExcelLength,oRange,vChnData,K

Set oRange = oSheet.range(oSheet.Cells(StartRow,ColNo),oSheet.Cells(StartRow+lExcelLength-1,ColNo))
oRange.Value = ChnToValue(oChn,"TransposedMatrix")
On Error Resume Next

On Error Goto 0

If ( "Yes" = oChn.Properties("novaluekey").Value ) Then
For K = 1 to oChn.Size
If ( IsNull(oChn(K)) ) Then
oSheet.Cells(StartRow+K-1,ColNo) = NULL
End If
Next
End If

If ( "time" = LCase(oChn.Properties("displaytype").Value) ) Then oRange.NumberFormat = "DD.MM.YYYY hh:mms"
If ( "text" = LCase(oChn.Properties("displaytype").Value) ) Then oRange.EntireColumn.AutoFit
On Error Goto 0

End Function
