Exception problem with polled tags

Hi all,

in my PI environment I have a lot of PI points configured in polled mode (Location3=0), and their scan class frequency is 1 second. For these points the exdev is set to 0,25, the exmax to 10 min and the compression is off. The OPC tags behind these point do not change their value also for more than one day. If I well understood how exception works, I do not expect to have all that same values archived every 1 second in the data archive. The problem is that every 1 second the same value is archived. It seems that the exception is not working. Any idea? Thanks a lot for your support!
