11.4.5 RTMS Format Description
The EBNF description of RTMS syntax is as follows:
Record = ( DataRecord | AckRecord ) CRLF.
DataRecord = StationName “,” TableName “ (“ FieldSpecs “) VALUES (“ FieldValues
“)”.
AckRecord = StationName “,” TableName “,” RecordNumber.
FieldSpecs = FieldName “ “ FieldType {“,” FieldName “ “ FieldType}.
FieldValues = FieldValue {“,” FieldValue}.
StationName = Label.
TableName = Label.
FieldName = Label.
Label = Letter { Letter | Digit }.
FieldType = ( “TIMESTAMP” | Decimal | “FLOAT” | “INTEGER” | VarChar ).
Decimal = “DECIMAL(“ Digit [ Digit ] “,” Digit [ Digit ] “)”.
VarChar = “VARCHAR(“ Digit { Digit } “)”.
FieldValue = ( TimeStamp | RecordNumber | Number | String ).
TimeStamp = “‘“ Year “–” Month “–” Day “ “ Hour “:” Minute “:” Second “‘“.
Year = 4( Digit ).
Month = 2( Digit ).
Day = 2( Digit ).
Hour = 2( Digit ).
Minute = 2( Digit ).
Second = 2( Digit ) [ “.” { Digit } ].
RecordNumber = 10{ Digit }.
Number = { Digit } [ “.” ] { Digit }.
String = “‘“ { Character } “‘“.
A typical data record might look something like this:
Lgr,Sec15 (TMSTAMP TIMESTAMP,RECNBR DECIMAL(10,0),Battery_V
FLOAT,Temp FLOAT) VALUES (‘1993-12-08
15:02:00’,123456,13.5,72.123)
Only without the tabs and carriage return in the middle. One with strings might
look like this.
PC1,StatMsg (TMSTAMP TIMESTAMP,RECNBR DECIMAL(10,0),SrcStn
VARCHAR(256),AbtStn VARCHAR(256),Hop DECIMAL(3,0),Message
VARCHAR(256)) VALUES (‘1993-12-08
15:02:02.25’,13355,’PC1’,’StatMsg’,0,’DBSelect End Pipe Queue Dump’)
The acknowledgment records to be sent back to the server for the two records
shown above would be:
Lgr,Sec15,123456
and
PC1,StatMsg,13355
