Calculate value on specific time range from another table

Hi, All

I would like to calculate some values(from PLC data) on specific time range(Excel report).

When I query data from PLC, it shows values with timestamp. Even I can calculate but it is not that meaningful.

Because we need to check whether it is dayoff or not on that time.

So, I would like to select specific time range based on the Excel report, then I hope to calcuate values with PLC data

here are the structures of Two data sets(PLC, Excel)

<PLC data : this value could be ideal time// trouble time> 

<Excel report : it shows start time and end time>
