Get PID block out of IMAN

I've created a simple control loop consisting of AI, PID, and AO blocks for the purpose of simulation on my DeltaV system, but I can't get the PID block out of IMAN. The only difference I can think of between this loop and others that are working is I haven't assigned any IO to the AI/AO blocks, and I've enabled simulate on the AI block.  I have the BKCAL_OUT from the AO block connected to the BKCAL_IN on the PID block and the status is GoodCascade so I don't understand why the PID block is in IMAN. Can someone offer suggestions as to what could be wrong?

  All looks good with the wiring.
  
  Please confirm the AO block simulate is enabled and statis is set to good
  
  Also if it is, what is the status of the bkcal_in of the PID block?

  I may be wrong but I agree with the replies that say the PID block should NOT work in the ProPlus of a real DeltaV system. I recommend you contact Tech Support before spending much time on having the PID in the ProPlus. I’ll look up the call mentioned by IntuitiveNeil!
