    Hi Anonymous 
    It was a wrong solution.

    Please refer to attached file with the correct solution

     

    Down Order = --column 
IF ( 
    'Nizhny Tagil#1'[HP GOX] = 1,
    RANKX ( 
        FILTER ( 'Nizhny Tagil#1', 'Nizhny Tagil#1'[HP GOX] = 1 ),
        VAR T1 = FILTER ( 'Nizhny Tagil#1', 'Nizhny Tagil#1'[Date] <= EARLIER ( 'Nizhny Tagil#1'[Date] ) )
        RETURN
            COUNTROWS (T1)
            - SUMX (
                T1,
                'Nizhny Tagil#1'[HP GOX]
            ),, 
            ASC, 
            Dense
    )
)
    Start Time = --measure
IF ( 
    NOT ISBLANK ( SELECTEDVALUE ( 'Nizhny Tagil#1'[Down Order] ) ),
    MIN ( 'Nizhny Tagil#1'[Date] )
)
    End Time = --measure
IF ( 
    NOT ISBLANK ( SELECTEDVALUE ( 'Nizhny Tagil#1'[Down Order] ) ),
    MAX ( 'Nizhny Tagil#1'[Date] )
)
    Downtime = --measure
SUMX (
    VALUES ( 'Nizhny Tagil#1'[Down Order] ),
    IF (
        'Nizhny Tagil#1'[Down Order] <> BLANK (),
        DATEDIFF ( [Start Time], [End Time], MINUTE )
    )
)

Hi Anonymous 

you need to create a calculated column that sort the down occurances in order. Then you can place this column in the table visual followed by the following measures.

 

 

Down Order = --column 
IF (
    'Table'[Column1] = 1,
    SUMX (
        FILTER ( 'Table', 'Table'[Date] <= EARLIER ( 'Table'[Date] ) ),
        'Table'[Column1]
    )
)
Start Time = --measure 
MIN ( 'Table'[Date] )
End Time = --measure 
MAX ( 'Table'[Date] )
Downtime = --measure 
SUMX (
    VALUES ( 'Table'[Down Order] ),
    IF (
        'Table'[Down Order] <> BLANK (),
        DATEDIFF ( [Satrt Time], [End Time], MINUTE)
    )
)
