| PropertyID | The server assigns DWORD ID codes to the properties. This allows the client to more easily manage the list of properties it wants to access. These properties are divided (somewhat arbitrarily) into 3 'sets'. The OPC 'Fixed' set contains properties that are identical to some of those returned by OPCITEMATTRIBUTES, the 'recommended' set is expected to be common to many servers, the 'vendor specific' set contains additional properties as appropriate. The assigned IDs for the first two sets are fixed. The vendor specific properties should use ID codes above 5000. |
