Hi Hati,

Thank for answering again.

Yes - each button has a word assigned to it. The buttons are used (as buttons) in the HMI (WinCC).

Not so sure what the FC will tell us but here is the screenshots.

What is FC1129 doing with the input? That should clarify this situation. It seems there is a Word assignment for each WinCC button.

 In stead of Using a input in the block for each state of the button, a pointer of the button status word is inserted to the block.
