This VariableType defines the general characteristics of a DiscreteItem that can have more than two states and where the state values (the enumeration) do not consist of consecutive numeric values (may have gaps) or where the enumeration is not zero-based.
The MultiStateValueDiscreteType derives from the DiscreteItemType. MultiStateValueDiscrete Variables can have any numeric Data Type; this includes signed and unsigned integers from 8 to 64 Bit length.
The numeric representation of the current enumeration value is provided via the Value Attribute of the MultiStateValueDiscrete Variable.
| UnifiedAutomation.UaServer.MultiStateValueDiscreteModel.MultiStateValueDiscreteModel | ( | ) |
Initializes a new instance of the MultiStateValueDiscreteModel class.
| UnifiedAutomation.UaServer.MultiStateValueDiscreteModel.MultiStateValueDiscreteModel | ( | MultiStateValueDiscreteModel | template, |
| DummyArgument | dummy = null |
||
| ) |
Initializes a new instance of the MultiStateValueDiscreteModel class.
| template | The template. |
| dummy | Dummy argument to enable writing own constructors that are called by the generated code. |
|
getset |
An array of EnumValueType where each entry of the array represents one enumeration value with its integer notation, a human-readable representation, and help information.
This represents enumerations with integers that are not zero-based or have gaps (e.g. 1, 2, 4, 8, 16). See UnifiedAutomation.UaBase.EnumValueType for the definition of this type. MultiStateValueDiscrete Variables expose the current integer notation in their Value Attribute. Clients will often read the EnumValues Property in advance and cache it to look up a name or help whenever they receive the numeric representation.
|
getset |
Provides the localized text representation of the enumeration value.
It can be used by Clients only interested in displaying the text to subscribe to the Property instead of the Value Attribute.
