Sample:

END_VAR
VAR
    fbNoSqlValidation : FB_NoSQLValidation(sNetID := '', tTimeout := t#15S);
    aRemainingData : ARRAY[0..1000] OF STRING(cDocumentSize);
END_VAR

IF fbNoSqlValidation.GetRemainingData(
    pData:= ADR(aRemainingData), 
    cbData:= SIZEOF(aRemainingData), 
    cbDocument:= cDocumentSize, 
    bDataRelease:= TRUE)
THEN
    IF fbNoSqlValidation.bError THEN    
        TcMessage := fbNoSqlValidation.ipTcResult;
        nstate := 255; 
    ELSE
        nstate := nstate+1;
