Package Modelica.Blocks.Types
Library of constants, external objects and types with choices, especially to build menus
Information
In this package types, constants and external objects are defined that are used
in library Modelica.Blocks. The types have additional annotation choices
definitions that define the menus to be built up in the graphical
user interface when the type is used as parameter in a declaration.
Extends from Modelica.Icons.TypesPackage (Icon for packages containing type definitions).

fixed=false)
SteadyState- Steady state initialization (derivatives of states are zero)
InitialState- Initialization with initial states

Enumeration Modelica.Blocks.Types.InitPID
Enumeration defining initialization of PID and LimPID blocks
Information
This initialization type is identical to Types.Init and has just one
additional option DoNotUse_InitialIntegratorState. This option
is introduced in order that the default initialization for the
Continuous.PID and Continuous.LimPID blocks are backward
compatible. In Modelica 2.2, the integrators have been initialized
with their given states where as the D-part has not been initialized.
The option DoNotUse_InitialIntegratorState leads to this
initialization definition.
The following initialization alternatives are available:
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 possible)
DoNotUse_InitialIntegratorState- Do not use, only for backward compatibility (initialize only integrator state)
