![]() | Description | Contains the Description of the Property. |
![]() | ItemName | See ItemPath. |
![]() | ItemPath | If this Item Property can be read, written or subscribed to then ItemPath and ItemName together uniquely identify this property in the server??s browse space. If ItemPath is empty, then ItemName by itself is a fully qualified name that uniquely identifies this element. If ItemPath and ItemName are both blank or missing, then this Item Property cannot be read, written or subscribed to. See the corresponding section in the OPC DA Custom Specification which references IOPCItemProperties::LookupItemIDs(). |
![]() | Name | Contains the Qualified name of the Property. |
![]() | ResultID | If an error or a non-critical exception (minor problem) occurred this ID will contain a qualified name. If the server also returns verbose error messages the respective OPCError elements will be located elsewhere in the message. This allows multiple instances of a Result ID to map to the same verbose OPC Error. See specification section 2.6 for more details about Resultcodes. |
![]() | Value | The current value of the property |
