(2) non-interaction mode, that is, borrow trust and log in, it is not necessary to which username and password is provided.
The reading of filing data.Most important concept is that " Tag (point), Tag are PI databases to different surveys in PI databases
The unique mark of point data stream.
Tag has two important attributes：Tag_Name and Point_Number, wherein Tag_Name are the names to point, and
Point_Number is internal indicator of the point in PI databases, and the data access to some point is all to pass through Point_Number
Complete.
The reading of data.The reading of data uses function PISDK.PIPoints.Data.Snapshot, and what it was returned is
The latest data value of point.Code below is to read the code of certain point snapshot value and property value：PI_Vale tPI_Value=New
PI_Vale；//PI_Vale is point data structure, comprising the moment, three member PIPoint pt=of numerical value and state
srv.PIPoints(TagName)；PIValue pv=pt.Data.Snapshot；// obtain snapshot value.tPI_
Value.Time=pv.TimeStamp.LocalDate//moment property value.TPI_Value.Value=pv.Value；// survey
Point data value.TPI_Value.IsGood=pv.IsGood；// state.
Database is closed.After PI databases have been accessed, it should database is closed in time, is disconnected, in order to avoid waste number
According to the system resource of storehouse server.The closing of PI databases realizes that this function is not by PISDK.Server.Close () function
With any parameter.
