Hi!
I'm facing a problem and I would like your help, guys. I have some calculated tags that use some other base tags to calculate its value. That base tags are mannual input or collected tag. The problem is that the user input the value in the mannual input tag at 8pm, for example, but using a timestamp of 00h of the same day. In other words, the user puts a value in the past. The problem is that my performance equation has already calculated the value for that time on the past that the user inputed the value. Because of this, that calculated data on the past now is wrong and should be recalculated.
I was wonder about an automatic solution to this problem and thought that it would be nice if I could create a kind of virtual tag that calculate its value only when it's called and getting the base values only when it's called as well. Is there any way to do this? Or, how can I solve my problem? I only want to recalculated a tag on the past using the new base tags values in a automatic way..
Thanks in advanced.
