Getting Integer Values for Digital State Pi Tags

Question: My goal is to get the integer value of a Digital State tag.  An example of the digital states for data a 'PhaseID' Pi point tag is shown below.  Using the Analysis option in Pi System Explorer, is there a Cast type or similar function where I can get the actual state number (int16('PhaseID')?) value of the digitalstate?

 

Example Pi Tag Name = 'PhaseID'

 

Example of Digital states for 'PhaseID' tag are summarized below:

State Number     State Name

0                          "Phase1"

1                          "Phase2"

2                          "Phase 3"

...                           ...

 

Alternatively, I can create another Pi point and Boolean logic using PEs to create integers for the different phases; however, the PE results are (non-integer) interpolated values and are not equivalent to the digital State - state number.  Does anyone have a suggestion on how to best resolve this issue?

 

Thanks in advance!
