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.

The following illustrations show the state diagrams for the custom client/Data

Export interface. (The diagramming notation is by Booch[1] who claims to

have adopted it from Harel [2]).
