The best I can come up with is PCDLRN.PartProgram.Probes, but I think that will only give you what probes are used in a program and nothing about them being loaded in the change rack. I don't see any properties in PCDLRN.Probe relating to the changer, as well as nothing in PCDLRN.Application, PCDLRN.ApplicationSettings or any other seemingly logical places to look.
Edit: I did find a PCDLRN.OBTYPE.GET_PROBECHANGER_DATA enumeration, maybe that in a GetValue function or something would do it, though I don't know what command you would actually need to interrogate with it.
