Enumeration defining initialization of PID and LimPID blocks
type InitPID = enumeration(NoInit "No initialization (start values are used as guess values with fixed=false)", SteadyState "Steady state initialization (derivatives of states are zero)", InitialState "Initialization with initial states", InitialOutput "Initialization with initial outputs (and steady state of the states if possibles)", DoNotUse_InitialIntegratorState "Don't use, only for backward compatibility (initialize only integrator state)");
