Best way to get last good value of a PI tag.

We have a requirement.

There is an attribute with a PI tag data reference.

There are associated min and max to this attribute.

We need to stream the latest good value. Value will be considered "good" if it is within the range (min/max) and is also not a BadVal from PI.

 

My idea is to perform the validation and save the output in an attribute, which will be streamed.

 

What analysis setup can be best for this case?

I have some ideas but cannot think of a way which will perfectly meet this requirement.
