能不能将他们导出到一个excel表里改（添加变量可以在excel表里改）。
答：
应该是可以，但我仅仅做过添加io域的。感觉不是非常的好用，反正我是测试后在没有用了。
在 Graphics Designer 中选择 Tools -> Macros -> Visual Basic Editor，该环境与 Excel 的宏环境类似。需要有一定的 VBA 基础，这里给一个简单的例程。在 D:\siemens\WinCCProjects\WinCC_test\test.xls 工作簿的sheet1 工作表中，第一列为 I/O 区域含义文本（比如启动速度），第二列为 I/O 区域直连变量（比如tag1）。
Sub CreateIOField()
Dim objStaticText As HMIStaticText
Dim objIOField As HMIIOField
Dim objVariableTrigger As HMIVariableTrigger
Set Excel_1 = CreateObject("excel.application")
Excel_1.Workbooks.Open "D:\siemens\WinCCProjects\WinCC_test\test.xls"
Set wksheet = Excel_1.Sheets("sheet1")
j = 30
K = 5
For i = 1 To 41
If wksheet.cells(i, 2).value <> "" Then
Set objStaticText = ActiveDocument.HMIObjects.AddHMIObject("0_MyText" & i, "HMIStaticText")
With objStaticText
.Text = wksheet.cells(i, 1).value
.Left = j
.Top = K
.Layer = 19
.AdaptBorder = True
End With
Set objIOField = ActiveDocument.HMIObjects.AddHMIObject("0_MyIOField" & i, "HMIIOField") ''IOField
With objIOField
.Left = j + 200
.Top = K
.Width = 45
.Height = 21
.OutputFormat = 999.9
End With
Set objVariableTrigger = objIOField.OutputValue.CreateDynamic(hmiDynamicCreationTypeVariableDirect, wksheet.cells(i, 2))
With objVariableTrigger
.CycleType = hmiVariableCycleTypeOnChange
End With
K = K + 22
End If
Next
Excel_1.Workbooks.Close
Excel_1.Quit
Set wksheet = Nothing
Set Excel_1 = Nothing
End Sub
