Allow TagVal to select a specific value if several values stored at a same timestamp
We have cases where we have several values for the same tag at a specific timestamp.
When we use tagVal in an analysis expression, the TagVal function returns the last stored value for the timestamp for the tag.
We would like to be able to get (using a parameter) the First value stored for our calculations.
Can you explain how you're getting multiple values for the same timestamp? What is writing these values?
