Extract a piece of a string and work with it (PI AF attributes)

Good morning mates, I have a problem which I do not know how to solve in PI AF 2014 R2.


I have an attribute that is a string, for example:





          Where X are numbers, sometimes more numbers and sometimes less (so the number of chars is variable)


I want to read this string and make a new attribute:


- If it is connected, the value will be 1.

- If it is disconnected, the value will be 0.


My problem is that I do not know any function in PI to do this. I have tried several things but I get nothing.


Any ideas? I think this issue could be useful to everybody.


Thanks a lot for your help.
