SDK Only retrieve 'Bad Values' from pi-point

I am working on a project that needs to retrieve data from a pi-point only whenever the value is 'Bad' within a certain timeframe, what is the syntax for this?

I know you can use a filtered expression for example something like tagval>200 to only receive values of the pi-point that are larger than 200 but how to do this to get only the values that are marked as bad?


Can this be done or not at all?


Kind regards.
