Summary
Example showing the difference between DisplayValue and EstimatedValue in a solution.
Technical Information
The DisplayValue property will show one of the three options: the Value tag property (the tag's current value (Value property).The ), the EstimatedValue tag property (which is a user-defined calculation), or a Historian Value of the tag.
Using this infrastructure, you can calculate the EstimatedValue to be as the unit conversion for the Value property and select if choose whether your display or another system will show the units dynamically.
The method to switch between multiple display values is through the "Client.Context.DisplayValueMode" property, where each given number changes its DisplayValue (i.e., if set to 0, it will show the original value; if set to 1, it will show the estimated value).
In the given example, the current estimation is done by obtaining the first three significant digits of your original number.
