大家好，我使用WINCC创建了一个用户归档数据来采集生产过程中的值。 现在每天都要手动使用Export按钮进行导出数据生成.csv文件，感觉好麻烦。有没有办法每天早上8点自动把用户归档里面采集的所有数据生成为.csv文件。如何实现？求高手指导。谢谢   我的WINCC是6.2版本。

通过不断的测试，问题已经解决啦，回来给大家分享一下成果，首先也感谢各位：

在全局C脚本写入以下代码：

#include "apdefap.h"

int CRT3884_UAExport(void)

{

UAHCONNECT hConnect;

UAHARCHIVE hArchive;

BOOL bOK;

int iRet = 0;

bOK = uaConnect(&hConnect);

if ((bOK == FALSE) (hConnect == NULL)){

  printf ("#E101: CRT3884_UAExport() - uaConnect failed!  error=%d\r\n", uaGetLastError());

  iRet = -101;

  return (iRet);

}

bOK = uaQueryArchiveByName(hConnect, "MyArchiv", &hArchive);

if ((bOK == FALSE) (hArchive == NULL)){

  uaDisconnect(hConnect);

  printf ("#E201: CRT3884_UAExport() - uaQueryArchiveByName failed!  error=%d\r\n", uaGetLastError());

  iRet = -201;

  return (iRet);

}

bOK = uaArchiveSetFilter(hArchive, "ChargeName like '%charge%' and DateBegin >= '2006-01-01 00:00:00' AND DateBegin < '2007-01-01'");

if (bOK == FALSE){

  printf ("#E301: CRT3884_UAExport() - uaArchiveSetFilter failed!  error=%d\r\n", uaGetLastError());

  iRet = -301;

  return (iRet);

}

bOK = uaArchiveSetSort(hArchive, "ChargeUser , ChargeName desc");

if (bOK == FALSE){

  printf ("#E302: CRT3884_UAExport() - uaArchiveSetSort failed!  error=%d\r\n", uaGetLastError());

  iRet = -302;

}

bOK = uaArchiveOpen(hArchive);

if (bOK == FALSE){

  uaReleaseArchive(hArchive);

  uaDisconnect(hConnect);

  printf ("#E401: CRT3884_UAExport() - uaArchiveOpen failed!  error=%d\r\n", uaGetLastError());

  iRet = -401;

  return (iRet);

}

bOK = uaArchiveExport(hArchive, "p:\\tmp\\MyArchive.csv", 0, 0);

if (bOK == FALSE){

  printf ("#E501: CRT3884_UAExport() - uaArchiveExport failed!  error=%d\r\n");

  iRet = -501;

}

bOK = uaArchiveClose(hArchive);

if (bOK == FALSE){

  printf ("#E801: CRT3884_UAExport() - uaArchiveClose failed!  error=%d\r\n", uaGetLastError());

  iRet = -801;

}

bOK = uaReleaseArchive(hArchive);

if (bOK == FALSE){

  printf ("#E802: CRT3884_UAExport() - uaReleaseArchive failed!  error=%d\r\n", uaGetLastError());

  iRet = -802;

}

bOK = uaDisconnect(hConnect);

if (bOK == FALSE){

  printf ("#E803: CRT3884_UAExport() - uaDisconnect failed!  error=%d\r\n", uaGetLastError());

  iRet = -803;

}

return (iRet);

然后编译保存，设置每天早上8：00 激活一次该代码。欧啦！
