Dear Gentlemen,

I try to make a trend window in Wincc Comfort SW, and I want to display archive Tags but it give me error [tag value invalid or No Connection]
Even I put this tag in Tag Logging
It worked only if I display Online Tags

If any one face this problem before, or any one can help me ???

Thanks in advance
