Continuing the discussion from [Flow to get output from a logical sequence of events](https://discourse.nodered.org/t/flow-to-get-output-from-a-logical-sequence-of-events/68447/5):

I am working on this flow to get the duration of each state. I need to get:  
A) the duration when D2 is 1,  
B) the duration when D1 is 1 (during the state when D2 was 1).

This will give me the cycle time of D1 and D2. When D2 is 0 and again the cycle starts, i should get the new cycle time. Each cycle should have an id no. could be an index no.

I am able to get D2 cycle time, but not D1.

Thanks

Hi,  
Wrote the following flow to get the cycle time:

```

this problem is solved.
