I have been having a problem with SQL Tags. I have converted my real time data over to decrease the constant pounding of the SQL tables. I found that when a machine is shut down the field in the applet bound to particular tags shows a different value than the tag itself, FactorySQl, and the SQL table. When I look in PMI Designer, the tag shows the value that is being displayed in the applet.
My guess is that this is a timing issue that is cause during machine shutdown.
Could use some help on this. I have had to bind my values back to SQL tables and our SQL Server is really getting pounded.
