Simulate each of the three scenarios. When you run the first, new plot windows open.

The numeric annotations on these figures refer to the three scenarios. Recall that T
Setpoint 1 uses the default blocking, which usually results in faster setpoint tracking
but larger manipulated variable moves. The blocking options in T Setpoint 2 and T
Setpoint 3 reduce the move size but make setpoint tracking more sluggish.
