前面的一篇博客记录了如何读取多个变量归档数据到mshgrid控件，根据的是西门子官网的教学。有网友询问为什么他照着官网方法就是无法导出到excel。我自己也做了一遍，没有问题。本篇主要记录导出按钮的脚本。

 

前面的准备工作与上一篇一致，导出按钮的vbs脚本如下：

Sub OnClick(ByVal Item)  
Dim myCatalog,myDS,PCName,cnstr,sqlstr1,sqlstr2
Dim xlapp,BTime,ETime,utcbtime,utcetime,utcbtstr,utcetstr

PCName=HMIRuntime.Tags("@LocalMachineName").Read 
myDS=PCName & "\Wincc"
Set BTime=HMIRuntime.Tags("btime")
Set ETime=HMIRuntime.Tags("etime")
'北京时间时区修正
utcbtime=Dateadd("h",-8,BTime.Read) '起始时间
utcetime=Dateadd("h",-8,ETime.Read) '结束时间
'日期时间格式修正
utcbtstr = Year(utcbtime) & "-" & Month(utcbtime) & "-" & Day(utcbtime) & " " & Hour(utcbtime) & ":" & Minute(utcbtime) & ":" & Second(utcbtime)

Set rsobj1 = comobj1.Execute

   exit sub

无法导出数据的朋友，检查一下官网提示的那个连接包是否安装了。
