of the datalogger name, table name and the record number of the received
record.
If the Data Export application loses its connection with the LoggerNet
communication server, it will need to be re-connected before any records can
be obtained and sent out.
There are two record formats used to send the record data:
RTMS format – this format is provided for backward compatibility for
customers who had the RTMS system and developed data handling procedures
that use the format provided by the RTMS socket export.
Standard format – this format provides an easily interpreted data string
containing the data along with format information for each data field.
Details on these formats are provided at the end of this section.

have adopted it from Harel [2]).
