Yeah I am worried about doing the import thru ignition. I have done some with a few thousand rows and it takes quite a while(20-30 minutes) using the csv parsing script.
I guess my first question if we use the import option thru scripting, what kind of performance hit would we take by writing this data into the tag history tables while the system is live? would we run into any deadlocks or anything?
Colby, we dont really have that option in this situation, since a 3rd party was hosting the data. I dont think it is a bad idea though. I may be looking at something similar pretty soon to access wonderware tag data. kepware makes a wonderware to opc driver that i may use to access tag data from a wonderware system without actually pulling the plug on it.
