Hello,
I am working on WinCC V7.4.0. 
I have written script in VBS for writing tags values to Excel file.

Previously, this action was taking place on click of a button on screen. It was working fine.
Now the requirement has been changed this writing operation has to take place when pushbutton is pressed (DI16.2). 
I have created a tag on a connection for this address and linked this tag as trigger for writing action, Standard cycle for this triggering tag was set as Upon Change then User Cycle1, 1s,2s respectively.

But the problem is everytime a button is pressed.This writing operation is taking place on change of signal(i.e when input goes from Low-to-High and from High-to-Low) writing operation is taking place 2 times whenever the button is pressed.

The operation requires writing operation to take place only once when the button is pressed.
Please suggest what should i do.
