I am trying to store sample data from a continuous process and I would like to trend these sample results along side historical OPC tags (temp, press, ect.). My problem is that I need these values to be time stamped when the sample was taken, not when the data is entered. I have created a table in the DB and am storing the sample results by sample time. I have played around with SQL tags, but if I set them as historical again, it stores the data at time of tag update. Any ideas?
