Increment variable after condition

Hi Guys,

 

I need a help with the case below:

How to write it in Dax or Powerquery a code like this below:

 

Expected Result =

VAR V_ID = 1
RETURN

    if('Table'[OverflowAlarm] = 1 && 'Table'[Previus row] = 0, V_ID, 
        if('Table'[OverflowAlarm] = 0 && 'Table'[Previus row] = 1,    V_ID = V_ID +1 ,

           if ('Table'[OverflowAlarm] = 1 && 'Table'[Previus row] = 1, 'Table'[OverflowAlarm],0
)))

 

I have a table like that:

Thanks for your response.

I am not a Power Bi expert, I've been working only few weeks with it. But, I couldn't see it working for me. And the function earlier doesn't work well... too many rows in the table, it runs forever... Any other solution?
