Hi everyone,

As i'am still a student and doing a final year tudy project I'am very new to TIA Portal and need as much help as i can get  . i'am not very familiar with VB scripts and i'am stuck for 3 weeks now in making one that would let me Export data from Wincc RT Professional v13 or v14 to an excel file continuously ( each 1h for exemple ) , the file would be filled each time with data in its buttom ( i don't want the old data to be erased) like this way :

     Date             Tag1 Value     Tag2 Value      Tag2 Value       Tag3 Value

8/4/2017  6:06       10                    1000                  0                        0.2

8/4/2017  7:07       11                    2000                  1                       20.3

8/4/2017  8:08        7                      200                   1                      3000.1

8/4/2017  9:09        5                     3000                  1                           7

i have looked to every VB scripts offered in the other topics but i either had an error while compiling it for exemple telling me 'Dim DataSet, ......' can't be declared as a tag , or having script that replace the old data , as for the data exported from trend view it can't be done continuously(automatically) (or can it ?) so does anyone have a script that can help me with this problem and tell me how to integrate it please ? i have been stuck with this for too long and i don't have much time left or i wouldn't bother you with this guy and have really looked everywhere else with no luck , so thank you very much in Advance !
