are these multiple files? or 2 files each night?
are the date times on the text file of help?

the text files could possibly be appended based on date time
multiple files. Each file goes from 12:00am till 11:59 pm. then a new one starts. That's the issue. But the times the cycles start and end are different depending on ramp rate and stuff. But the values in the columns i mentioned always contain those values when it starts/ends. But the beginning end are often in two separate files if it runs overnight.

So I think the best would be to create a loop and assign values to new files using multiple conditions? I am just not sure exactly how to do this...
