Detailed Description

Defines the general characteristics of a DiscreteItem that can have more than two states.

The value of the DiscreteItem is delivered as UInteger but the EnumStrings Property defined by the MultiStateDiscreteType provides display strings for every possible state value.

The EnumStrings Property is also used for Enumeration DataTypes.

The StatusCode delivered with the value also contains an informational bit called SemanticsChanged. Servers that implement Data Access shall set this Bit in notifications if the EnumStrings (changes can cause misinterpretation by users or (scripting) programs) Property is changed. Clients that use any of these Properties should re-read them before they process the data value.

In addition a server can send SemanticChangeEvents if the value of the Property EnumStrings is changed. To indicate this capability, the SemanticChange flag must be set in the AccessLevel and UserAccessLevel attributes of this variable.

Property Documentation

LocalizedText [] UnifiedAutomation.UaServer.MultiStateDiscreteModel.EnumStrings
getset

EnumStrings is a string lookup table corresponding to sequential numeric values of the variable (0, 1, 2, etc.).

Example:"OPEN""CLOSE""IN TRANSIT" etc. Here the string"OPEN" corresponds to 0, "CLOSE" to 1 and"IN TRANSIT" to 2.

If the item contains an array then this lookup table shall apply to all elements in the array.

The EnumStrings Property is also used for Enumeration DataTypes.
