10 OPC UA DataTypes

10.1 ResetModeEnum

This enumeration defines the possible values of the input argument of the FactoryReset Method. The enumeration is defined in Table 281.

Its representation in the AddressSpace is defined in Table 282.

10.2 ExecutionModeEnum

This enumeration defines the possible values of the input argument of the AutoAdjustPositioner Method. The enumeration is defined in Table 283.

Its representation in the AddressSpace is defined in Table 284.

10.3 PatDictionaryEnum

This enumeration defines the possible values of the PatDictionary element in the ChemicalSubstanceDataType structure. The enumeration is defined in Table 285.

Its representation in the AddressSpace is defined in Table 286.

10.4 ChemicalSubstanceDataType

This structure contains a label and an ID describing a chemical substance. The structure is defined in Table 287.

PatDictionary: identifier that determines the type of information given by the Id. It can obtain the following values given by its DataType PatDictionaryEnum:

0 (CAS): the Id is a CAS Registry Number for a chemical substance defined in the CAS Registry by the Chemical Abstracts Service

1 (PAT): the Id is a term that describes a measurand or matrix component related to a PAT device, that doesn’t have a CAS number. PAT terms are defined in IEC CDD.

2 (user-defined): the Id is a term without definition. It is applied when neither CAS nor PAT terms match the measurement task.

Id: defined identification term that enables machine readability and comparability.

Label: non-defined descriptive term for the measurand or matrix. It can be adapted to the preferences and needs of manufacturers and users to achieve a common sense understanding of the measuring task.

Example: PatDictionary = 0 (CAS), Label = “O2”, Id = “7782-44-7”. This identifies oxygen.

Its representation in the AddressSpace is defined in Table 288.
