List archive values (piarc​.dif)

The piconfig input file PI\adm\piarc.dif allows you to quickly view archive data with piconfig:

@input piarc.dif
Next, enter data with the format:
tagname, starttime, endtime, count

For example, to view four hours of data for the tag sinusoid, with a maximum of 100 values, type:

@input piarc.dif
sinusoid, *-4h, *, 100
@endsection

You can also use the PIARC table to view interpolated data by specifying the even mode. In this example, five evenly spaced values will be retrieved:

* (Ls - PIARC) piconfig> @table piarc
* (Ls - PIARC) piconfig> @istru tag, starttime, endtime, count, mode
* (Ls - PIARC) piconfig> @ostr value,status,time
* (Ls - PIARC) piconfig> @ostr ...
* (Ls - PIARC) piconfig> sinusoid,*,*-4h,5,even
*> sinusoid,*,*-4h,5,even
