In this exercise we will show you how to use the Configure dialog in the DeltaV Explorer to add a parameter to the list of configurable parameters and modify its properties. (You can also make this type of change in Control Studio.) To be able to use the simulation capabilities we need to enable the SIMULATE_D parameter on the DC block of the NC_VALVE module class. Therefore, we will add SIMULATE_D to the list of configurable parameters and then enable it.
