Keep in mind, CPS does not get warrants, law enforcement departments do (police or sheriff).
If a law enforcement agency were to obtain a warrant, they could execute that warrant - the scope of that warrant would depend on the exact terms of whatever order the judge was actually willing to issue.
I don't know all of the terms of your case (and we cannot provide formal or individual legal advice here), but in general, these orders do not provide for interstate enforcement.
If your child is currently vacationing over the holiday weekend with grandparents this is going to be difficult for a CPS worker to claim you are "secreting" the child. But again, keep in mind, you are not required to speak with these individuals, and you are not required to permit them into your home.
You do have a 5th Amendment right against self incrimination, and you have been willing to set an appointment to meet with them with your attorney present. Beyond that there really isn't much more to provide.
A law enforcement officer may ask about the whereabouts of the child to confirm welfare, but that is going to be limited to confirming that the child is with grandparents and is safe.
