Hi, everybudy. I need your help to insert into PI database about 600 rows twice a  day in a automatic way. Each row has mora than 10 tags. The data source of this is SQLSERVER 2008.-

My problem is that i don't know how to make a connection to the PI DB, if it is possible, and if not, how should I do  

To insert those rows.

I'll apreciate an example as detail as possible.-
