All the momentary actions trigger the action for a 100-millisecond period for each
message received. The one shot actions trigger the action once for each message
received. For example, sending one step from state message would cause the
controller to step into the next state one time. The continuous actions trigger that
action indefinitely. So the set hold in state action will cause the controller to hold
in the current state until the clear hold in state action is received and the exit state
condition is meet.
