PID Simulation

Hi there,

Question:  Why does enabling the simulation on a PID block forces the block to Manual due to BAD_PV status ?

Status: I simply want to simulate the functionality of a PID block by putting it into simulation mode but I could not because the block is forced to manual.

Intention:  I would like to do the simulation.

DeltaV version: 12.0

Please note that I understand in DeltaV parameters are defined by both values & status.  Do I need to somehow force the status to GOOD for this simulation?  

Regards,
